Detailed Description

The unicode data-type: i.e. wchar.

This supports encoding elements that are wider than 1-byte

Member Function Documentation

◆ clone()

virtual Datatype * TypeUnicode::clone ( void ) const

inlinevirtual

Clone the data-type.

Reimplemented from TypeBase.

References TypeUnicode().

◆ restoreXml()

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

protected

Restore this unicode data-type from an XML element.

Parse a <type> tag for properties of the data-type

Parameters

el	is the root XML element
typegrp	is the factory owning this data-type

References Datatype::metatype, Datatype::restoreXmlBasic(), setflags(), SUB_INT_UNICODE, SUB_UINT_UNICODE, Datatype::submeta, and TYPE_INT.

Referenced by TypeFactory::restoreXmlTypeNoRef().

◆ saveXml()

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

s	is the stream to write to

Reimplemented from Datatype.

References a_v_b(), Datatype::metatype, Datatype::saveXmlBasic(), Datatype::saveXmlTypedef(), and Datatype::typedefImm.

◆ setflags()

void TypeUnicode::setflags ( void )

private

Set unicode property flags.

Properties that specify which encoding this type uses are set based on the size of the data-type. I.e. select UTF8, UTF16, or UTF32

References Datatype::chartype, Datatype::flags, Datatype::size, Datatype::utf16, and Datatype::utf32.
