Member Typedef Documentation

typedef PlainSharedPtr<AbstractDateTime> Patternist::AbstractDateTime::Ptr

A smart pointer wrapping AtomicValue instances.

Reimplemented from Patternist::AtomicValue.

Reimplemented in Patternist::Date, Patternist::DateTime, Patternist::GDay, Patternist::GMonth, Patternist::GMonthDay, Patternist::GYear, Patternist::GYearMonth, and Patternist::Time.

Member Function Documentation

QString AbstractDateTime::dateToString ( ) const

Returns:: m_datetime's date part converted to string. This is for example "2004-05-12" or "-2004-05-12".

Definition at line 241 of file AbstractDateTime.cpp.

References m_datetime, and KDateTime::toString().

Referenced by Patternist::DateTime::stringValue(), and Patternist::Date::stringValue().

Here is the call graph for this function:

Here is the caller graph for this function:

Item::Ptr AbstractDateTime::fromValue ( const KDateTime & 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 in Patternist::Date, Patternist::DateTime, and Patternist::Time.

Definition at line 296 of file AbstractDateTime.cpp.

bool AbstractDateTime::isRangeValid	(	const QDate &	date,
		QString &	message
	)			`[static]`

Determines whether dt is a date-time that can be represented, and isn't too early or too late. If it is valid, true is returned. Otherwise, false is returned and message is set to contain a translated message for human consumption, describing the error.

Here is the caller graph for this function:

QString AbstractDateTime::serializeMSeconds ( const MSecondProperty msecs ) [static]

Serializes the milli seconds msecs into a string representation. For example, if msecs is 1, ".001" is returned; if msecs is 100 then is ".1" returned.

Here is the caller graph for this function:

QString AbstractDateTime::timeToString ( ) const

Returns:: m_datetime's time part converted to string. This is for example "12" or "01.023".

Here is the caller graph for this function:

KDateTime AbstractDateTime::toDateTime ( ) const [virtual]

Returns:: the date time this class represents, as a KDateTime.

Definition at line 291 of file AbstractDateTime.cpp.

References m_datetime.

QString AbstractDateTime::zoneOffsetToString ( ) const [protected]

Returns:: m_datetime' zone offset converted to string, as per the the W3C XML Schema types. This is for example "Z" or "+12.00"(depending on m_datetime).
