Package ghidra.app.plugin.assembler.sleigh.parse

Class AssemblyParseState

java.lang.Object

ghidra.app.plugin.assembler.sleigh.parse.AssemblyParseState

All Implemented Interfaces:

Comparable<AssemblyParseState>

public class AssemblyParseState
extends Object
implements Comparable<AssemblyParseState>

A state in an LR(0) parsing machine

Each item consists of a kernel and an implied closure. Only the kernel is necessary to define the item, but the whole closure must be considered when deriving new states. The kernel can be retrieved and mutated via getKernel(), then the closure derived from it via getClosure().
