dvt:resourceUtilizationGantt resourceUtilizationGantt resource utilization gantt

UIComponent class: oracle.adf.view.faces.bi.component.gantt.UIResourceUtilizationGantt
Component type: oracle.dss.adf.gantt.ResourceUtilizationGantt

The ResourceUtilizationGantt is typically used to illustrate how many units (ex. hours) are allocated and utilized for a particular resource in a given time period. It comprises of two major parts; the left side of the Resource Utilization Gantt shows information about the resources in the form of columns in the Table, while the right side of the Resource Utilization Gantt displays graphical representation of the resource utilized for the resource at a specific time.

This component can have the following children: ganttLegend, collectionDropTarget, dropTarget

The ResourceUtilizationGantt provides a set of predefined styles out of the box. For a complete set of predefined styles, please consult the javadoc for oracle.adf.view.faces.bi.component.gantt.UIResourceUtilizationGantt for details. Applications can also define their own styles or make changes to predefined styles by registering their own TaskbarFormat object through the TaskbarFormatManager. For details, please see the javadoc for oracle.adf.view.faces.bi.component.gantt.TaskbarFormat and oracle.adf.view.faces.bi.component.gantt.TaskbarFormatManager classes.

Gantt Model

The ResourceUtilizationGantt component uses a model to access the data in the underlying list. Like the TreeTable component, the ResourceUtilizationGantt supports hierarchical data. The specific model class is org.apache.myfaces.trinidad.model.TreeModel.

The collection of objects returned by TreeModel must have, at the minimal, the following properties:

Optionally, the object could implement the oracle.adf.view.faces.bi.model.Resource interface to ensure it provides the correct properties to the Gantt.

The collection of objects returned by the timeBuckets property must also have the following properties:

Optionally, the object could implement the oracle.adf.view.faces.bi.model.TimeBucket interface to ensure it provides the correct properties to the Gantt.

Columns

A user would specify what columns to display in the left side of the Gantt by adding the Column components as its children. For more information see the documentation for <af:column>.

Like the TreeTable, a "nodeStamp" facet is used to specify the primary identifier of an element in the hiearchy. For example, the "Resource Name" Column might be used as the nodeStamp for the ResourceUtilization Gantt.

Legend

A legend can be attached to the Gantt by adding the ganttLegend component. The legend toggle button in the toolbar would only be available if a legend is attached and is visible.

Drag And Drop

The ResourceUtilizationGantt can be made as a drop target for Table, TreeTable by using the dropTarget tag. Note that the Table, TreeTable must first be specified as a drag source before their content can be drop onto the Gantt. Please see the documentation for <af:dragSource>.

actionListener javax.el.MethodExpression Only EL a method reference to an actionListener that will be called when an action is performed on the Gantt.
attributeChangeListener javax.el.MethodExpression Only EL a method reference to an attribute change listener. Attribute change events are not delivered for any programmatic change to a property. They are only delivered when a renderer changes a property without the application's specific request. An example of an attribute change events might include the width of a column that supported client-side resizing.
attributeConverterFactory oracle.adf.view.faces.bi.component.gantt.AttributeConverterFactory Yes Specifies an AttributeConverterFactory that provides Converters for various task attributes rendered within tooltips, context menus, and the information panel of the legend. (In order for the "startTime", "endTime", and "completedThrough" attributes to be properly formatted within the tooltips rendered during task resizes and moves, the Converter returned by the AttributeConverterFactory must implement the org.apache.myfaces.trinidad.convert.ClientConverter interface.
backgroundColor String Yes the background color for the Gantt. A hex string is expected. (ex: #FF33FF)
binding String Only EL an EL reference that will store the component instance on a bean. This can be used to give programmatic access to a component from a backing bean, or to move creation of the component to a backing bean.
contentDelivery String Yes Valid Values: lazy, immediate, whenAvailable

whether data should be fetched when the component is rendered initially. When contentDelivery is "immediate", data is fetched and inlined into the component chrome. If contentDelivery is "lazy", data will be fetched and delivered to the client during a subsequent request. If contentDelivery is "whenAvailable", the model is queried for available data during initial rendering: If data is available, it will render as if contentDelivery="immediate", else it will render as if contentDelivery="lazy".
currentDate java.util.Date Yes the current date that should be highlighted in the Gantt.
customTimeScales java.util.Map Yes Specifies custom time scales for this gantt. The type is Map<String, CustomTimeScale>. The String being used for the map key is the custom time scale name. The value is the implementation of the CustomTimeScale interface. Gantt will use this map to render custom time scales.
customizationId String Yes This attribute is deprecated. The 'id' attribute should be used when applying persistent customizations. This attribute will be removed in the next release.
dataChangeListener javax.el.MethodExpression Only EL a method reference to a dataChangeListener that will be called when an action that would change the data is performed on the Gantt.
disclosedRowKeys org.apache.myfaces.trinidad.model.RowKeySet Yes The set of disclosed rows for this component. Each entry in the set is a rowKey.
displayRow String Yes Valid Values: first, last, selected

The row to display during initial display. The possible values are "first" to display the first row, "last" to display the last row and "selected" to display the first selected row. The default value for this is null which means that the first row is displayed. Please note that this API will have no effect if the total number of rows are not known from the table model (model.getRowCount()==-1).
displayRowKey Object Yes The rowKey to display during initial display. Specifying this attribute will override the displayRow attribute. Please note that this API will have no effect if the total number of rows are not known from the table model (model.getRowCount()==-1).
dontPersist String[] Yes a list of persistent attributes that are restricted from persisting to a registered "Persistent Change Manager". Persistent attributes would still persist to a session.
doubleClickListener javax.el.MethodExpression Only EL a method reference to a timeBucketDoubleClickListener that will be called when a double click is performed on a time bucket.
endTime java.util.Date Yes the end time that is used to render the time period of the Gantt.
featuresOff String[] Yes Valid Values: edit, clipboard, print, undo, legend, zoom, view, filter, properties

a list of default features to turn off for the resourceUtilizationGantt.

filterListener javax.el.MethodExpression Only EL a method reference to a filterListener that will be called when a different filter is selected.
filterManager oracle.adf.view.faces.bi.component.gantt.FilterManager Yes overrides the default FilterManager with an application defined FilterManager. The FilterManager contains a list of application defined filters which limit the tasks to display in the Gantt. See the javadoc for oracle.adf.view.faces.bi.component.gantt.FilterManager for details.
first int Yes This attribute is deprecated. The 'displayRow' or 'displayRowKey' attributes should be used instead. This attribute will be removed in the next release.
goToDateConverter javax.faces.convert.Converter Yes Specifies a Converter to be used for the dates displayed in the "Go To Date" dialog of the gantt.
highlightColor String Yes the color used for the highlighted time period. A hex string is expected. (ex: #FF33FF)
highlightEndTime java.util.Date Yes the end time of the highlighted time period.
highlightStartTime java.util.Date Yes the start time of the highlighted time period.
horizontalFetchSize int Yes the size of the horizontal data window in number of pixels in which the data are fetched. Only task bars within this data window would be rendered. In contrast with fetchSize, which provides vertical virtualization, horizontalFetchSize provides horizontal virtualization.
id String Yes Specifies the identifier for the component
initialDateFocus java.util.Date Yes Specifies the initial date displayed when the the gantt comes up.
initiallyExpandAll boolean Yes Specifies whether the rows should be initially expanded.
inlineStyle String Yes Specifies CSS styles to use for this component. This is intended for basic style changes; you should use the skinning mechanism if you require any complex style changes. The inlineStyle is a set of CSS styles that are applied to the root DOM element of the component. Many components are composed of several DOM elements which may have their own styles applied to them. Defining a style in the inlineStyle may not always give you what you want. For example, if one of the inner DOM elements for this component has a background color specified for it in the skin, setting a background color in the inlineStyle may not provide any visible change (at least for where that inner DOM element exists) because the inner DOM element's background color will win (since that DOM element is essentially layered on top of the root element). In cases like this, you can use a different skin (or define your own) that defines a skinning key for that inner DOM element where its background color is inhibited (e.g. with -tr-inhibit: background-color) or otherwise set to the color you want.
labelPlacement String Yes Valid Values: top, center

Specifies the placement of the label relative to the taskbar.
metricConverter javax.faces.convert.Converter Yes Specifies a Converter to be used for the numbers shown on the data bars.
metrics String[] Yes a list of metrics used in the Resource Utilization Gantt. Note that the values are also used to identify the TaskbarFormat from TaskbarFormatManager.
nonWorkingDays java.util.Date[] Yes a whitespace delimited list of dates that should be highlighted as non-working days in the Gantt.
nonWorkingDaysColor String Yes the color used to highlight the non-working days or non-working days of the week. A hex string of the color is expected. (ex: #FF33FF)
nonWorkingDaysOfWeek String[] Yes Valid Values: sun, mon, tue, wed, thu, fri, sat

a whitespace delimited list of weekdays that should be highlighted as non-working days in every week. The list should consist of one or more of the following abbreviations: sun, mon, tue, wed, thu, fri, sat.
partialTriggers String[] Yes the IDs of the components that should trigger a partial update. This component will listen on the trigger components. If one of the trigger components receives an event that will cause it to update in some way, this component will request to be updated too. Identifiers are relative to the source component, and must account for NamingContainers. If your component is already inside of a naming container, you can use a single colon to start the search from the root, or multiple colons to move up through the NamingContainers - "::" will search from the parent naming container, ":::" will search from the grandparent naming container, etc.
persist String[] Yes a list of persistent attributes that are persisting to a registered "Persistent Change Manager". Persistent attributes, by default, always persist to a session.
rendered boolean Yes whether the component is rendered. When set to false, no output will be delivered for this component.
resourceSelectionListener javax.el.MethodExpression Only EL a method reference to a resourceSelectionListener that will be called when a resource is selected.
rowResizable boolean Yes whether the row can be resize.

showToolbar boolean Yes whether the toolbar should be shown in the Gantt. Note that if this is set to false, then any custom toolbar buttons specified in the toolbar facet will also be hidden.
sortListener javax.el.MethodExpression Only EL a method reference to a sortListener that will be called when a column in the Gantt is sorted (using the arrow buttons in the column header).
splitterPosition int Yes the initial location of the splitter between the data region and the chart region, in number of pixels.
startTime java.util.Date Yes the start time that is used to render the time period of the Gantt.
styleClass String Yes Sets a CSS style class to use for this component.
summary String Yes Sets a summary of this Gantt's purpose and structure for user agents rendering to non-visual media (e.g. screen readers).
taskbarFormatManager oracle.adf.view.faces.bi.component.gantt.TaskbarFormatManager Yes overrides the default TaskbarFormatManager with an application defined TaskbarFormatManager. The TaskbarFormatManager contains a registry of the types of task bar that are displayed in the Gantt and the visual representation of each of these type of task bars. See the javadoc for oracle.adf.view.faces.bi.component.gantt.TaskbarFormatManager for details.
timeBucketSelectionListener javax.el.MethodExpression Only EL a method reference to a timeBucketSelectionListener that will be called when a time bucket is selected.
timeZone java.util.TimeZone Yes Specifies a global TimeZone for the gantt. If not set, the timezone is pulled from the AdfFacesContext.

Note this attribute is always used in conjunction with tooltipKeyLabels, and the number of keys should match the number of labels.
undoManager oracle.adf.view.faces.bi.component.gantt.UndoManager Yes overrides the default UndoManager with an application defined UndoManager. The UndoManager manages undoable entries as a result of certain actions performed on the Gantt. See the javadoc for oracle.adf.view.faces.bi.component.gantt.UndoManager for details.
value org.apache.myfaces.trinidad.model.TreeModel Yes the Gantt data - must be of type org.apache.myfaces.trinidad.model.TreeModel.
var String Yes Name of the EL variable used to reference each element of this collection. Once this component has completed rendering, this variable is removed (or reverted back to its previous value).
