Detailed Description

template<const bool isDouble>
class QPatternist::NumericToAbstractFloatCaster< isDouble >

Casts a numeric value, such as xs:integer or xs:float, to xs:double or xs:float.

castFrom() uses Numeric::toDouble() for doing the actual casting.

Functions

castFrom()

template<const bool isDouble>

Item QPatternist::NumericToAbstractFloatCaster< isDouble >::castFrom ( const Item &  from, const QExplicitlySharedDataPointer< DynamicContext > &  context  ) const

virtual

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.
