Method Detail

accept

public void accept(CodeVisitor v)

The accept() method implements one half of the visitor pattern so that client visitors can traverse the syntax tree easily and in an extensible way.

Specified by:

accept in class Expr

Parameters:

v - the visitor to accept

accept

public Expr accept(CodeRebuilder r)

The accept() method implements one half of the visitor pattern for rebuilding of expressions. This visitor allows code to be slightly modified while only writing visit methods for the parts of the syntax tree affected.

Specified by:

accept in class Expr

Parameters:

r - the rebuilder to accept

Returns:

the result of calling the appropriate visit() method of the rebuilder
