Class MarkerExpressionFilter

java.lang.Object
  atg.process.filter.Filter
      atg.process.filter.ExpressionFilter
          atg.markers.scenario.MarkerExpressionFilter

All Implemented Interfaces:

MarkerConstants

Direct Known Subclasses:

BusinessProcessExpressionFilter, ItemHasMarker, OrderHasMarker

public abstract class MarkerExpressionFilter
extends ExpressionFilter
implements MarkerConstants

This abstract class can be implemented to create a marker expression filter.

This class provides access to a configuration component of type MarkerConfiguration.

Accessor methods are provided to return the configurable property values from the configuration component. By default, each of the accessor methods returns the configured value from the MarkerConfiguration componenent. However these methods can be extended to return dynamic values.

Method Detail

getMarkerConfiguration

protected MarkerConfiguration getMarkerConfiguration()

setMarkerConfiguration

protected void setMarkerConfiguration(java.lang.Object pConfiguration)
                               throws ProcessException

Throws:

ProcessException

configure

public void configure(java.lang.String pOperator,
                      java.lang.Object pConfiguration)
               throws ProcessException,
                      java.lang.UnsupportedOperationException

The configuration object provides the reference to the the RepositoryMarkerManager and also the default parameter values.

Overrides:

configure in class ExpressionFilter

Throws:

ProcessException - if the filter could not be configured - for example, because some of the required properties are missing from the configuration

java.lang.UnsupportedOperationException - if this filter is not configurable

MarkerConfiguration

initialize

public void initialize(java.lang.String pOperator,
                       Expression[] pOperands)
                throws ProcessException

Initializes this ExpressionFilter, given its operator and operands. The default implementation of this method simply sets the operator and operands properties.

Overrides:

initialize in class ExpressionFilter

Parameters:

pOperator - the filter operator names

pOperands - the operands to the filter.

Throws:

ProcessException - if the operands argument is invalid

getKey

protected java.lang.String getKey(ProcessExecutionContext pContext)
                           throws ProcessException

Returns the key parameter.

This parameter is expected to be element zero in the parameter array.

Returns:

String the key

Throws:

ProcessException

getValue

protected java.lang.String getValue(ProcessExecutionContext pContext)
                             throws ProcessException

Returns the value parameter.

This parameter is expected to be element one in the parameter array.

Returns:

String the value

Throws:

ProcessException

getData

protected java.lang.String getData(ProcessExecutionContext pContext)
                            throws ProcessException

Returns the data parameter.

This parameter is expected to be element two in the parameter array.

Returns:

String the data

Throws:

ProcessException

getMarkerPropertyName

protected java.lang.String getMarkerPropertyName(ProcessExecutionContext pContext)

Returns the markerPropertyName.

By default, the marker configuration's defaultMarkerPropertyName is returned.

Override this method to return an alternate value such as something provided as a parameter or derived dynamically based on the context.

getMarkerItemType

protected java.lang.String getMarkerItemType(ProcessExecutionContext pContext)

Returns the markerItemType.

By default, the marker configuration's defaultMarkerItemType is returned.

Override this method to return an alternate value such as something provided as a parameter or derived dynamically based on the context.

getMarkedItemType

protected java.lang.String getMarkedItemType(ProcessExecutionContext pContext)

Returns the markedItemType.

By default, the marker configuration's defaultMarkedItemType is returned.

Override this method to return an alternate value such as something provided as a parameter or derived dynamically based on the context.

getDuplicationMode

protected java.lang.String getDuplicationMode(ProcessExecutionContext pContext)

Returns the duplcationMode.

By default, the marker configuration's defaultDuplicationMode is returned.

Override this method to return an alternate value such as something provided as a parameter or derived dynamically based on the context.

getRepositoryMarkerManager

protected RepositoryMarkerManager getRepositoryMarkerManager()

Returns the cofigured RepositoryMarkerManager.

getExtendedProperties

protected java.util.Map getExtendedProperties(ProcessExecutionContext pContext)

This method is called by the evaluate method to return the extendedProperties map.

The based implementation returns null.
