Class ItemHasMarker

java.lang.Object

atg.process.filter.Filter

atg.process.filter.ExpressionFilter

atg.markers.scenario.MarkerExpressionFilter

atg.markers.scenario.ItemHasMarker

All Implemented Interfaces:

MarkerConstants

Direct Known Subclasses:

ProfileHasMarker

public abstract class ItemHasMarker
extends MarkerExpressionFilter
implements MarkerConstants

This abstract class can be extended to create marker test expressions for any type of repository item.

Extensions must provide the repository item to used in the hasMarker API calls, and also map the new expressions operator names to the ones provided by this class.

The operator names provided by this class are:
hasMarker
hasLastMarker
hasLastMarkerWithKey

See Also:

getItemToUse(atg.process.ProcessExecutionContext), MarkerConfiguration.getHasMarkerOperatorMap()

Method Detail

getItemToUse

protected abstract RepositoryItem getItemToUse(ProcessExecutionContext pContext)

This method is called by the evaluate method to provide the RepositoryItem that's used in the hasMarker API calls.

Parameters:

pContext - the scenario execution context

Returns:

RepositoryItem the repository item that contains the markers

getHasMarkerOperatorToPerform

protected java.lang.String getHasMarkerOperatorToPerform(ProcessExecutionContext pContext)

This method is called by the evaluate method to determine the operator name.

By default, this method uses the operator name returned by getOperator to lookup to the appropriate base operator name provided by ItemHasMarker.

The base operator names for ItemHasMarker are: hasMarker, hasLastMarker and hasLastMarkerWithKey

Because this class can be extended to implement any number of scenario hasMarker expressions, the new expression operator names must be mapped in the configuration component to one of the standard operators above.

Returns:

String the operator name

See Also:

MarkerConfiguration.getHasMarkerOperatorMap()

initialize

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

called by Scenario Manager to initialize the expression

Overrides:

initialize in class MarkerExpressionFilter

Parameters:

pOperator - the filter operator names

pOperands - the operands to the filter.

Throws:

ProcessException - if the operands argument is invalid

evaluate

protected Filter evaluate(ProcessExecutionContext pContext)
                   throws ProcessException

Evaluates this filter in the given process execution context.

The possible return values of this method are as follows:

• Filter.TRUE - if the filter can be fully evaluated, and is satisfied in the given context
• Filter.FALSE - if the filter can be fully evaluated, and is not satisfied in the given context

Specified by:

evaluate in class Filter

Throws:

ProcessException - if there is a problem evaluating the filter (other than information missing from the context)
