fromValue()

Item Date::fromValue ( const QDateTime &  dt ) const

virtual

A factory function for creating instances that are of the dynamic type of this class, that represents dt.

The default implementation performs an assert() call. This function is not pure virtual because all sub-classes do not use it.

Reimplemented from QPatternist::AbstractDateTime.

Definition at line 99 of file qdate.cpp.

{
    Q_ASSERT(dt.isValid());
    return fromDateTime(dt);
}

stringValue()

QString Date::stringValue ( ) const

virtual

Implements QPatternist::AtomicValue.

Definition at line 105 of file qdate.cpp.

{
    return dateToString() + zoneOffsetToString();
}

type()

ItemType::Ptr Date::type ( ) const

virtual

Implements QPatternist::AtomicValue.

Definition at line 110 of file qdate.cpp.

{
    return BuiltinTypes::xsDate;
