方法详细资料

copy

public VariableInstruction copy(VariableInstruction variableInstruction)

Copies the given instruction into this instruction.

参数:

variableInstruction - the instruction to be copied.

返回:

this instruction.

isStore

public boolean isStore()

Returns whether this instruction stores the value of a variable. The value is false for the ret instruction, but true for the iinc instruction.

isLoad

public boolean isLoad()

Returns whether this instruction loads the value of a variable. The value is true for the ret instruction and for the iinc instruction.

canonicalOpcode
