Constructor & Destructor Documentation

◆ LabSymbol() [1/2]

ghidra::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(), ghidra::Symbol::displayName, and ghidra::Symbol::name.

◆ LabSymbol() [2/2]

ghidra::LabSymbol::LabSymbol ( Scope * sc )

Constructor for use with decode.

Parameters

sc	is the Scope that will contain the new Symbol

References buildType().

Member Function Documentation

◆ buildType()

void ghidra::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.

References ghidra::Scope::getArch(), ghidra::TypeFactory::getBase(), ghidra::Symbol::scope, ghidra::Symbol::type, ghidra::TYPE_UNKNOWN, and ghidra::Architecture::types.

◆ decode()

void ghidra::LabSymbol::decode ( Decoder & decoder )

virtual

Decode this Symbol from a stream.

Parse a Symbol from the next element in the stream

Parameters

decoder is the stream decoder

Reimplemented from ghidra::Symbol.

References ghidra::Decoder::closeElement(), ghidra::Symbol::decodeHeader(), and ghidra::Decoder::openElement().

◆ encode()

void ghidra::LabSymbol::encode ( Encoder & encoder ) const

virtual

Encode this Symbol to a stream.

Parameters

encoder is the stream encoder

Reimplemented from ghidra::Symbol.
