public abstract class MethodCallNode extends FlowNode
Represents a method call node in the flow graph. When control passes to a method call node, its
MethodExpression
is invoked, passing any parameters. Let outcome be the value determined by the following algorithm. If there is anull
return from the invocation,getOutcome()
is called. If the result is non-null
, itsgetValue()
method is called and the value is considered to be outcome. If there is a non-null
return, let it be outcome. Convert outcome to a String by calling itstoString
method. Use outcome to determine the next node in the flow graph.- Since:
