Detailed Description

A Symbol that labels code internal to a function.

Constructor & Destructor Documentation

LabSymbol() [1/2]

LabSymbol::LabSymbol	(	Scope *	sc,
		const string &	nm
	)

Construct given name.

Parameters

sc	is the Scope that will contain the new Symbol
nm	is the name of the new Symbol

References buildType(), and Symbol::name.

LabSymbol() [2/2]

LabSymbol::LabSymbol

(

Scope *

sc

)

Constructor for use with restoreXml.

Parameters

sc	is the Scope that will contain the new Symbol

References buildType().

Member Function Documentation

buildType()

void LabSymbol::buildType ( void  )

private

Build placeholder data-type.

Label symbols don't really have a data-type, so we just put a size 1 placeholder.

restoreXml()

void LabSymbol::restoreXml ( const Element *  el )

virtual

Restore this Symbol from an XML stream.

Parameters

el	is the root XML tag of the symbol

Reimplemented from Symbol.

References Symbol::restoreXmlHeader().

saveXml()

void LabSymbol::saveXml ( ostream &  s ) const

virtual

Save this Symbol to an XML stream.

Parameters

s	is the output stream

Reimplemented from Symbol.
