Method Detail

rewrite

public Node rewrite(PaoTypeSystem ts,
                    NodeFactory nf)

Rewrites instanceof checks where the comparison type is a primitive type to use the boxed type instead. For example, "e instanceof int" gets rewritten to "e instanceof polyglot.ext.pao.runtime.Integer".

Specified by:

rewrite in interface PaoExt

Overrides:

rewrite in class PaoExt_c

Parameters:

ts - The PaoTypeSystem instance.

nf - The NodeFactory instance.

Returns:

the result of rewriting the AST node to provide boxing and unboxing.
