Class ViewStyleHandle

java.lang.Object
oracle.dss.util.format.BaseMergeableHandle
oracle.dss.dataView.ViewStyleHandle

All Implemented Interfaces:

Styleable

public class ViewStyleHandle

extends BaseMergeableHandle

implements Styleable

Wrapper class for returning a ViewStyle to a view from the data source, through the DataAccess interface.

ViewStyleHandle objects are used by data sources that supply their own formatting for cells in a view.

• For formatting cells in a GridView databody, a data source returns a ViewStyleHandle when the GridView passes DataMap.DATA_VIEWSTYLE as the type parameter of the DataAccess.getValue method.
• For formatting individual cells in a GridView header or in a paging control, a data source returns a ViewStyleHandle when a view passes MetadataMap.METADATA_VIEWSTYLE as the type parameter of the DataAccess.getMemberMetadata method.
• For formatting a layer in a crosstab, a data source returns a ViewStyleHandle when a view passes LayerMetadataMap.LAYER_METADATA_VIEWSTYLE as the type parameter of the DataAccess.getLayerMetadata method. A layer includes all the member cells for a particular dimension. It also includes the dimension label, when Crosstab.isPivotLabelVisible returns true.

The view uses the ViewStyle that this handle wraps, to determine the foreground color, background color, and so on, for a cell. The settings in the wrapped ViewStyle take precedence over those in the default ViewStyle for a view component.

If a data source has ViewStyleHandle objects both for a layer and for its member metadata cells, then the formatting for the individual cells takes precedence over the formatting for the entire layer.

The RunRulesForViewStyle property of this ViewStyleHandle determines whether the view runs rules that can modify the wrapped ViewStyle. If the view does not run rules, then the wrapped ViewStyle specifies all of the style properties for the cell.

Constructor Detail

ViewStyleHandle

public ViewStyleHandle()

Constructor that takes no arguments. If you use this constructor, you must set the ViewStyle for this ViewStyleHandle to wrap, and you must specify whether rules apply to the cell. You can also set a unique ID for the ViewStyle.

See Also:

setViewStyle(oracle.dss.dataView.managers.ViewStyle), setRunRulesForViewStyle(int), setViewStyleID(java.lang.String)

ViewStyleHandle

public ViewStyleHandle(ViewStyle vs,
                       java.lang.String id,
                       int runRules)

Constructor that specifies a ViewStyle, an ID, and whether rules apply to the cell.

Parameters:

vs - The ViewStyle for this object to wrap.

id - A unique ID for the ViewStyle.

runRules - A constant that indicates whether rules set on the view should be run for a cell that uses vs. Valid constants are listed in the See Also section.

See Also:

BaseMergeableHandle.RUN_RULES, BaseMergeableHandle.DO_NOT_RUN_RULES

Method Detail

getViewStyle

public ViewStyle getViewStyle()

Retrieves the ViewStyle that this ViewStyleHandle wraps. The settings in the ViewStyle that this method returns take precedence over the default ViewStyle for a view component.

Specified by:

getViewStyle in interface Styleable

Returns:

The ViewStyle for this ViewStyleHandle, or null if no ViewStyle has been specified.

setViewStyle

public void setViewStyle(ViewStyle vs)

Specifies the ViewStyle that this object wraps. The settings in the ViewStyle that you pass to this method take precedence over the default ViewStyle for a view component.

Specified by:

setViewStyle in interface Styleable

Parameters:

vs - The ViewStyle for this ViewStyleHandle.

getViewStyleID

public java.lang.String getViewStyleID()

Retrieves the ID of the ViewStyle that this ViewStyleHandle wraps.

Returns:

The ID for the wrapped ViewStyle, or null if no ID has been specified.

setViewStyleID

public void setViewStyleID(java.lang.String id)

Specifies a unique ID for the ViewStyle that this ViewStyleHandle wraps.

Parameters:

id - An ID for the wrapped ViewStyle.

getRunRulesForViewStyle

public int getRunRulesForViewStyle()

Indicates whether the view should run rules on the cell for which the ViewStyle provides formatting. If the view runs rules, then the settings in the ViewStyle can be overridden by those specified in the rules. If the view does not run rules, then the settings in the ViewStyle determine the formatting for the cell.

Returns:

A constant that indicates whether the view should run rules that can override settings in the ViewStyle that this ViewStyleHandle wraps. Valid constants are listed in the See Also section.

See Also:

BaseMergeableHandle.RUN_RULES, BaseMergeableHandle.DO_NOT_RUN_RULES

setRunRulesForViewStyle

public void setRunRulesForViewStyle(int runRules)

Specifies whether the view should run rules on the cell for which the ViewStyle provides formatting. If the view runs rules, then the settings in the ViewStyle can be overridden by those specified in the rules. If the view does not run rules, then the settings in the ViewStyle determine the formatting for the cell.

Parameters:

runRules - A constant that indicates whether the view should run rules that can override settings in the ViewStyle that this ViewStyleHandle wraps. Valid constants are listed in the See Also section.

See Also:

BaseMergeableHandle.RUN_RULES, BaseMergeableHandle.DO_NOT_RUN_RULES

getXML

public oracle.dss.util.xml.ObjectNode getXML(java.lang.String name,
                                             boolean allProperties)

Retrieves XML that represents properties and their values in the form of and ObjectNode.

Parameters:

allProperties - true to store all property values in XML, false to store only values that are different from default values.

Returns:

XML for the properties and values.

setXML

public void setXML(oracle.dss.util.xml.ObjectNode node)

Specifies XML that represents properties and values.

Parameters:

node - ObjectNode that has the properties and their values.
