namedWindowName - the named window name

consumerObject - an object that identifies the consumer, the same instance or the add and for the remove event

statementName - statement name

agentInstanceId - agent instance id

filterExpressions - filter expressions

exprEvaluatorContext - for expression evaluation

Method Detail

getFilterExpressions

public ExprNode[] getFilterExpressions()

Provides the filter expressions.

Evaluate filter expressions, if any, as follows: Boolean pass = filterExpressions[...].getExprEvaluator().evaluate(new EventBean[] {vdwEvent}, true, addEvent.getExprEvaluatorContext());

Filter expressions must be evaluated using the same ExprEvaluatorContext instance as provided by this event.

Returns:

filter expression list

getExprEvaluatorContext

public ExprEvaluatorContext getExprEvaluatorContext()

Returns the expression evaluator context for evaluating filter expressions.

Returns:

expression evaluator context
