构造器详细资料

SimpleInstruction

public SimpleInstruction()

Creates an uninitialized SimpleInstruction.

SimpleInstruction

public SimpleInstruction(byte opcode)

Creates a new SimpleInstruction with the given opcode. Automatically extracts any embedded constant.

SimpleInstruction

public SimpleInstruction(byte opcode,
 int constant)

Creates a new SimpleInstruction with the given opcode and constant. Automatically adapts the opcode if it has an embedded constant and the constant lies within the supported range. If the constant doesn't lie within the supported range, it must be adapted before the instruction can be written out.

方法详细资料

copy

public SimpleInstruction copy(SimpleInstruction simpleInstruction)

Copies the given instruction into this instruction.

参数:

simpleInstruction - the instruction to be copied.

返回:

this instruction.

canonicalOpcode

public byte canonicalOpcode()

从类复制的说明: Instruction

Returns the canonical opcode of this instruction, i.e. typically the opcode whose extension has been removed.

覆盖:

canonicalOpcode 在类中 Instruction

shrink

public Instruction shrink()

从类复制的说明: Instruction

Shrinks this instruction to its shortest possible form.

指定者:

shrink 在类中 Instruction

返回:

this instruction.

readInfo

protected void readInfo(byte[] code,
 int offset)

从类复制的说明: Instruction

Reads the data following the instruction opcode.

指定者:

readInfo 在类中 Instruction

writeInfo

protected void writeInfo(byte[] code,
 int offset)

从类复制的说明: Instruction

Writes data following the instruction opcode.

指定者:

writeInfo 在类中 Instruction

length

public int length(int offset)

从类复制的说明: Instruction

Returns the length in bytes of the instruction.

指定者:

length 在类中 Instruction

accept

public void accept(Clazz clazz,
 Method method,
 CodeAttribute codeAttribute,
 int offset,
 InstructionVisitor instructionVisitor)

从类复制的说明: Instruction

Accepts the given visitor.

指定者:

stackEntryIndexBefore

public int stackEntryIndexBefore(Clazz clazz,
 int stackEntryIndexAfter)

从类复制的说明: Instruction

Returns the stack entry index from which the specified stack entry is copied by a dup/swap/checkcast instruction, or -1 otherwise. Stack entry indices are counted from the top of the stack.

• checkcast: after: 0 (before: 0 ) -- not anymore
• dup: after: 0 0 (before: 0 )
• dup_x1: after: 0 1 0 (before: 1 0 )
• dup_x2: after: 0 2 1 0 (before: 2 1 0 )
• dup2: after: 1 0 1 0 (before: 1 0 )
• dup2_x1: after: 1 0 2 1 0 (before: 2 1 0 )
• dup2_x2: after: 1 0 3 2 1 0 (before: 3 2 1 0)

覆盖:

stackEntryIndexBefore 在类中 Instruction
