QueryImpl ( const String & query_string = "" )

Construct new QueryImpl object.

QueryImpl ( Node * ast )

Construct new QueryImpl from AST tree. Used internally to build representation of bracketed sub expressions.

const QueryErrorDesc& GetErrorDescription ( ) const

const String& GetQueryString ( ) const

Retrieve query String.

bool IsEmpty ( ) const

Check if query was empty, ie matching all.

bool IsValid ( ) const

Find out if the query String is valid.
