public class Instruct
extends AssemblyElement

Provides a representation of the instruct in the assembly language codes.

An instruct consists of an opcode, which is followed by a list of operands( or no operands for some opcodes).
For example,
add $s0,$s1,$s2
where, "add" is an opcode, "$s0", "$s1" and "$s2" are the operands.
The examples of representing the instructs of x86 assembly language and mips assembly language can be respectively found in the descriptions of X86Opcode and MIPSOpcode.

Instruct

public Instruct(Opcode opcode,
                java.util.List<Instruct.Operand> operands)

Constructs an object to represent an instruct.

参数：

opcode - the opcode of this instruct

operands - a list of the operands of this instruct. It should be null, if the operands has no operands. The member of this list is of type Operand.

方法详细信息

opcode

public Opcode opcode()

Gets the opcode of this instruct.

返回：

the opcode of this instruct.

operands

public java.util.List<Instruct.Operand> operands()

Gets the operands of this instruct.

返回：

a list of the operands ,or null if this instruct has no operand. The member of this list is of type Operand.

toString

public java.lang.String toString()

Returns a string representation of the instruct. The representation consists of the string representation of the opcode, which is followed by the string representations of the operands seperated by the comma.

覆盖：

类 java.lang.Object 中的 toString

返回：

the string representation of this instruct.
