filter - the search filter AST root

searchCtls - the JNDI search controls

Returns:

enumeration over SearchResults

Throws:

javax.naming.NamingException - if the search fails

evaluate

public boolean evaluate(ExprNode filter,
                        java.math.BigInteger id)
                 throws javax.naming.NamingException

Evaluates a filter on an entry with a id.

Parameters:

filter - the filter root AST node

id - the id of the entry to test
