Class MethodCallNode
- Direct Known Subclasses:
MethodCallNodeImpl
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 a null
return from the invocation, getOutcome()
is called. If the
result is non-null
, its getValue()
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 its toString
method. Use outcome to determine the next node in the flow graph.
