callingConstructor

private CMethod callingConstructor

The constructor that contains this expression.

method

private CMethod method

prefix

private JExpression prefix

ident

private String ident

args

private JExpression[] args

isPrefixSynthesized

private boolean isPrefixSynthesized

true if the prefix is a synthesized one (e.g., JAV_OUTER_THIS) as the result of typechecking.

argsCompleted

private boolean argsCompleted

Flag indicates whether the arguments have been processed to include outer this parameters for inner classes.

public JExplicitConstructorInvocation(TokenReference where,
                                      JExpression prefix,

Parameters:

where - the line of this node in the source code

prefix - a qualifying outer class for subclasses of inner class, see JLS2, 8.8.5.1

ident - the method name

args - the argument of the call
