public void addPath(java.lang.String s)
             throws OQLSyntaxException

Adds an attribute path that should also be queried.

Throws:

OQLSyntaxException

appendConstraints

public java.util.List<java.lang.String> appendConstraints(java.lang.StringBuilder sb,
                                                          java.util.List args,
                                                          java.lang.String terms)

Appends appropriate OQL "where" clauses for the given search terms to the given StringBuilder.

Parameters:

sb - the StringBuilder to append the contraints to

args - the parameter values to use (probably for comparisons) in the query

terms - the (probably user entered) text search terms (including possibly "must" and "mustnt" modifiers) as well as additional raw "where" clauses (that is anything TextQueryLexer can handle)

Returns:

a list of OQL clauses that could not be handled; which normally should be OQL clauses entered using '[' prefix
