Class MethodCallNode


  • 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.
