public class JNEMethodInvocationExpression

extends ExpressionNode

Jeva parse node for Method invocation expressions: target.method(args...) [JavaLangSpec 1.0 sec 15.11 Method Invocation Expressions]. Uses type of target expression to determine signature of method to be called. The implementation of this signature may be overridden by subclasses of this type, so the type of the actual target value is also needed.
