Detailed Description

An XML based encoder.

The underlying transfer encoding is an XML document. The encoder is initialized with a stream which will receive the XML document as calls are made on the encoder.

Member Function Documentation

◆ closeElement()

void ghidra::XmlEncode::closeElement ( const ElementId & elemId )

virtual

End the current element in the encoding.

The current element must match the given annotation or an exception is thrown.

Parameters

elemId is the given (expected) annotation for the current element

Implements ghidra::Encoder.

References depth, ghidra::ElementId::getName(), newLine(), outStream, tag_content, tag_start, tag_stop, and tagStatus.

◆ openElement()

void ghidra::XmlEncode::openElement ( const ElementId & elemId )

virtual

Begin a new element in the encoding.

The element will have the given ElementId annotation and becomes the current element.

Parameters

elemId is the given ElementId annotation

Implements ghidra::Encoder.

References depth, ghidra::ElementId::getName(), newLine(), outStream, tag_start, and tagStatus.

◆ writeBool()

void ghidra::XmlEncode::writeBool	(	const AttributeId &	attribId,
		bool	val
	)

virtual

Write an annotated boolean value into the encoding.

The boolean data is associated with the given AttributeId annotation and the current open element.

Parameters

attribId	is the given AttributeId annotation
val	is boolean value to encode

Implements ghidra::Encoder.

References ghidra::a_v_b(), ghidra::AttributeId::getName(), outStream, tag_content, tag_start, and tagStatus.

◆ writeOpcode()

void ghidra::XmlEncode::writeOpcode	(	const AttributeId &	attribId,
		OpCode	opc
	)

virtual

Write a p-code operation opcode into the encoding, associating it with the given annotation.

Parameters

attribId	is the given annotation
opc	is the opcode

Implements ghidra::Encoder.

References ghidra::AttributeId::getName(), outStream, tag_content, tag_start, and tagStatus.

◆ writeSignedInteger()

void ghidra::XmlEncode::writeSignedInteger	(	const AttributeId &	attribId,
		intb	val
	)

virtual

Write an annotated signed integer value into the encoding.

The integer is associated with the given AttributeId annotation and the current open element.

Parameters

attribId	is the given AttributeId annotation
val	is the signed integer value to encode

Implements ghidra::Encoder.

References ghidra::a_v_i(), ghidra::AttributeId::getName(), outStream, tag_content, tag_start, and tagStatus.

◆ writeSpace()

void ghidra::XmlEncode::writeSpace	(	const AttributeId &	attribId,
		const AddrSpace *	spc
	)

virtual

Write an address space reference into the encoding.

The address space is associated with the given AttributeId annotation and the current open element.

Parameters

attribId	is the given AttributeId annotation
spc	is the address space to encode

Implements ghidra::Encoder.

References ghidra::a_v(), ghidra::AttributeId::getName(), ghidra::AddrSpace::getName(), outStream, tag_content, tag_start, and tagStatus.

◆ writeString()

void ghidra::XmlEncode::writeString	(	const AttributeId &	attribId,
		const string &	val
	)

virtual

Write an annotated string into the encoding.

The string is associated with the given AttributeId annotation and the current open element.

Parameters

attribId	is the given AttributeId annotation
val	is the string to encode

Implements ghidra::Encoder.

References ghidra::a_v(), ghidra::AttributeId::getName(), outStream, tag_content, tag_start, and tagStatus.

◆ writeStringIndexed()

void ghidra::XmlEncode::writeStringIndexed	(	const AttributeId &	attribId,
		uint4	index,
		const string &	val
	)

virtual

Write an annotated string, using an indexed attribute, into the encoding.

Multiple attributes with a shared name can be written to the same element by calling this method multiple times with a different index value. The encoding will use attribute ids up to the base id plus the maximum index passed in. Implementors must be careful to not use other attributes with ids bigger than the base id within the element taking the indexed attribute.

Parameters

attribId	is the shared AttributeId
index	is the unique index to associated with the string
val	is the string to encode

Implements ghidra::Encoder.

References ghidra::AttributeId::getName(), and outStream.

◆ writeUnsignedInteger()

void ghidra::XmlEncode::writeUnsignedInteger	(	const AttributeId &	attribId,
		uintb	val
	)

virtual

Write an annotated unsigned integer value into the encoding.

The integer is associated with the given AttributeId annotation and the current open element.

Parameters

attribId	is the given AttributeId annotation
val	is the unsigned integer value to encode

Implements ghidra::Encoder.
