public class FieldInsnNode
extends AbstractInsnNode

Represents a field instruction. A field instruction is an instruction that loads or stores the value of a field of an object.

java.lang.String	name The field's name.
int	objectRegister The object register.
java.lang.String	owner The internal name of the field's owner class.

Constructor Detail

FieldInsnNode

public FieldInsnNode(int opcode,
                     java.lang.String owner,
                     java.lang.String name,
                     java.lang.String desc,
                     int valueRegister,
                     int objectRegister)

Constructs a new FieldInsnNode.

Parameters:

opcode - the opcode of the type instruction to be visited. This opcode is either IinstanceOP and SstaticOP.

owner - the internal name of the field's owner class.

name - the field's name.

desc - the field's descriptor.

valueRegister - the value register.

objectRegister - the objectRegister. Ignored for static operations.

Method Detail

setOpcode

public void setOpcode(int opcode)

Sets the opcode of this instruction.

Parameters:

opcode - the new instruction opcode. This opcode must be GETSTATIC, PUTSTATIC, GETFIELD or PUTFIELD.

getType

public int getType()

Description copied from class: AbstractInsnNode

Returns the type of this instruction.

Specified by:

getType in class AbstractInsnNode

Returns:

the type of this instruction, i.e. one the constants defined in this class.

accept

public void accept(MethodVisitor mv)

Description copied from class: AbstractInsnNode

Makes the given code visitor visit this instruction.

Specified by:

accept in class AbstractInsnNode

Parameters:

mv - a code visitor.

clone

public AbstractInsnNode clone(java.util.Map<LabelNode,LabelNode> labels)

Description copied from class: AbstractInsnNode

Returns a copy of this instruction.

Specified by:

clone in class AbstractInsnNode

Parameters:

labels - a map from LabelNodes to cloned LabelNodes.

Returns:

a copy of this instruction. The returned instruction does not belong to any InsnList.
