Field Detail

langInterested

public boolean langInterested

Tells whether any xpath parsed by this parser uses lang() function.
This is used by xpath engine to avoid tracking of language when none of xpaths used lang() function.

constraints

public ArrayList constraints

this list contains all constraints created by parser. when a constraint is created its id is computed from the size of this list. Stub classes also use this list to find whether the requested constraint is already created or not
