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 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.
