Class Bytecode.Switch

java.lang.Object

wyil.util.AbstractBytecode

wyil.lang.Bytecode.Switch

All Implemented Interfaces:

Bytecode, Bytecode.Stmt

Enclosing interface:

Bytecode

public static final class Bytecode.Switch
extends AbstractBytecode
implements Bytecode.Stmt

A switch bytecode has the following layout:

 +--------+-----------+-------+-----+-------+------------+-----+------------+
 | opcode | condition | block | ... | block | Constant[] | ... | Constant[] |
 +--------+-----------+-------+-----+-------+------------+-----+------------+
 

Here, the condition identifies the expression being switched on. There are zero or more case blocks, and the same number of constant arrays. An empty constant array indicates the default block.
