Detailed Description

A data-flow edge to which a resolved data-type can be assigned.

The edge is associated with the specific data-type that needs to be resolved, which is typically a union or a pointer to a union. The edge collapses different kinds of pointers to the same base union.

Constructor & Destructor Documentation

ResolveEdge()

ghidra::ResolveEdge::ResolveEdge	(	const Datatype *	parent,
		const PcodeOp *	op,
		int4	slot
	)

Construct from components.

Parameters

parent	is a parent data-type that needs to be resolved
op	is the PcodeOp reading/writing the parent data-type
slot	is the slot (>=0 for input, -1 for output) accessing the parent

Member Function Documentation

operator<()

bool ghidra::ResolveEdge::operator< ( const ResolveEdge &  op2 ) const

inline

Compare two edges.

Compare based on the data-type, the slot, and the PcodeOp's unique id.

Parameters

op2	is the other edge to compare with this

Returns

true if this should be ordered before the other edge
