Method Detail

addReference

public void addReference()

Add a reference on this NotificationEvent. After Usage removeReference must be called.

calcConstraintKey

public static String calcConstraintKey(String domain_name, String type_name)

Provide a Uniform Mapping from domain_name and type_name to a Key that can be used to put EventTypes into a Map. if (d1 == d2) AND (t1 == t2) => calcConstraintKey(d1, t1) == calcConstraintKey(d2, t2).

Parameters: domain_name a String value type_name a String value

Returns: an Unique Constraint Key.

doReset

protected void doReset()

extractFilterableData

public abstract EvaluationResult extractFilterableData(EvaluationContext context, ComponentName componentRootNode, String variable)

extractValue

public EvaluationResult extractValue(EvaluationContext context, ComponentName componentRootNode, RuntimeVariable runtimeVariable)

extractValue

public EvaluationResult extractValue(EvaluationContext evaluationContext, ComponentName componentRootNode)

extractVariableHeader

public abstract EvaluationResult extractVariableHeader(EvaluationContext context, ComponentName componentRootNode, String variable)

getConstraintKey

public abstract String getConstraintKey()

get the Constraint Key for this Event. The Constraint Key is used to fetch the Filter Constraints that must be evaluated for this Event. The Constraint Key consists of domain_name and type_name of the Event.

Returns: a String value
