This supports encoding elements that are wider than 1-byte

Member Function Documentation

void TypeUnicode::restoreXml	(	const Element *	el,
		TypeFactory &	typegrp
	)

protectedvirtual

Restore data-type from XML.

Restore a Datatype object from an XML element

Parameters

el	is the XML element
typegrp	is the underlying TypeFactory that will hold the new object

Reimplemented from Datatype.

References Datatype::restoreXmlBasic().

Referenced by TypeFactory::restoreXmlTypeNoRef().

void TypeUnicode::saveXml ( ostream & s ) const

virtual

Serialize the data-type to XML.

Write out a formal description of the data-type as an XML <type> tag. For composite data-types, the description goes down one level, describing the component types only by reference.

Parameters
