Constructor Details

RefExpRemover

public RefExpRemover(ExpressionPool pool,
 boolean _recursive)

Parameters:

_recursive -

If true, this object behaves destructively. It recursively visits all the reachable expressions and removes ReferenceExps. In this process, this object changes the content model of ElementExps.

If false, this object doesn't visit the content models of child elements, therefore, it behaves non-destructively. Nothing in the original expression will be touched.
