Specified by:

addReturnValue in interface ReturnEvent.Exporter

Parameters:

value - the return value

addNumber

public void addNumber(long n)

Description copied from interface: Event.Exporter

Get the sequence number of this event. Each event has a unique sequence number with respect to a single execution.

Specified by:

addNumber in interface Event.Exporter

Description copied from interface: Event.Exporter

Adds the thread on which this event took place.

Specified by:

addThreadID in interface Event.Exporter

Parameters:

thread - the thread identifier

checkForMatch

public boolean checkForMatch(JiveSearchPattern pattern,
                             RelationalOperator operator,
                             String rightValue)

Returns whether the event is a method return represented by the supplied JiveSearchPattern and whether the return value condition holds.

Parameters:

pattern - the pattern to check against

operator - the relational operator for the return value condition

rightValue - the right operand

Returns:

true if the method return can be associated with the pattern and the condition holds, false otherwise
