Detailed Description

template<TypeOfDerivedString DerivedType>
class QPatternist::ToStringCaster< DerivedType >

Casts any atomic value to xs:string.

This class uses Item::stringValue() for retrieving a string representation, and thus supports casting from atomic values of any type.

virtual Item QPatternist::ToStringCaster< DerivedType >::castFrom ( const Item &  from, const QExplicitlySharedDataPointer< DynamicContext > &  context  ) const

inlinevirtual

Casts from to an atomic value of the type this class casts to, and returns that value. The context is used for reporting errors in case the casting fails, and to in general access information from the dynamic context.

Implements QPatternist::AtomicCaster.
