accept()

void joda::query::ValToPredicate::accept ( class PredicateVisitor &  v )

overridevirtual

Uses the given PredicateVisitor to traverse the predicate tree with the visitor pattern.

Parameters

v	the visitor to use.

Implements joda::query::Predicate.

check()

bool joda::query::ValToPredicate::check ( const RapidJsonDocument &  val )

overridevirtual

Checks if a given document fulfills the given predicate

Parameters

val	the document to check

Returns

true if the document fulfills the predicate, else false.
