Method Detail

visit

public void visit(org.objectweb.asm.MethodVisitor mv,
                  Frame frame,
                  PClass clazz,
                  boolean forAssignment)

forAssignment - This indicates that the expression is evaluated to be assigned a value. In this case the last element should not be evaluated (e.g. obj.name should only push obj onto the stack, but to the value of "name".

getResultType

public PType getResultType()

toString

public java.lang.String toString(java.lang.String indent)
