Detailed Description

An annotation for a data element to being transferred to/from a stream.

This class parallels the XML concept of an attribute on an element. An AttributeId describes a particular piece of data associated with an ElementId. The defining characteristic of the AttributeId is its name. Internally this name is associated with an integer id. The name (and id) uniquely determine the data being labeled, within the context of a specific ElementId. Within this context, an AttributeId labels either

An unsigned integer
A signed integer
A boolean value
A string

The same AttributeId can be used to label a different type of data when associated with a different ElementId.

Constructor & Destructor Documentation

◆ AttributeId()

ghidra::AttributeId::AttributeId	(	const string &	nm,
		uint4	i
	)

Construct given a name and id.

This constructor should only be invoked for static objects. It registers the attribute for inclusion in the global hashtable.

Parameters

nm	is the name of the attribute
i	is an id to associate with the attribute

References getList().

Member Function Documentation

◆ find()

uint4 ghidra::AttributeId::find ( const string & nm )

inlinestatic

Find the id associated with a specific attribute name.

The name is looked up in the global list of all attributes. If the attribute is not in the list, a special placeholder attribute, ATTRIB_UNKNOWN, is returned as a placeholder for attributes with unrecognized names.

Parameters

nm	is the name of the attribute

Returns: the associated id

References id, and lookupAttributeId.

Referenced by ghidra::XmlDecode::getNextAttributeId(), operator==(), and ghidra::ElementId::operator==().

◆ getList()

vector< AttributeId * > & ghidra::AttributeId::getList ( void )

staticprivate

Retrieve the list of static AttributeId.

Access static vector of AttributeId objects that are registered during static initialization The list itself is created once on the first call to this method.
