The field's descriptor (see Type).

Constructor Detail

FieldInsnNode

public FieldInsnNode(int opcode,
                     String owner,
                     String name,
                     String desc)

Constructs a new FieldInsnNode.

Parameters:

opcode - the opcode of the type instruction to be constructed. This opcode must be GETSTATIC, PUTSTATIC, GETFIELD or PUTFIELD.

owner - the internal name of the field's owner class (see getInternalName).

name - the field's name.

desc - the field's descriptor (see Type).

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 cv)

Description copied from class: AbstractInsnNode

Makes the given code visitor visit this instruction.

Specified by:

accept in class AbstractInsnNode

Parameters:

cv - a code visitor.

clone

public AbstractInsnNode clone(Map 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.
