Package ghidra.app.plugin.assembler.sleigh.sem

Class AssemblyContextGraph.Edge

java.lang.Object

ghidra.app.plugin.assembler.sleigh.sem.AssemblyContextGraph.Edge

All Implemented Interfaces:

GEdge<AssemblyContextGraph.Vertex>, Comparable<AssemblyContextGraph.Edge>

Enclosing class:

AssemblyContextGraph

protected static class AssemblyContextGraph.Edge
extends Object
implements GEdge<AssemblyContextGraph.Vertex>, Comparable<AssemblyContextGraph.Edge>

A transition in a context transition graph

A transition consists of the constructor whose context changes were applied. The operand index is included for reference and debugging. If we ever need to process rules with multiple sub-constructors, the operand index explains the sub-table name of the destination vertex.
