Field Detail

var

public int var
The operand of this instruction. This operand is either a value or a source Register.


destinationRegister

public int destinationRegister
The destination register.

Constructor Detail

VarInsnNode

public VarInsnNode(int opcode,
                   int destinationRegister,
                   int var)
Constructs a new VarInsnNode.

Parameters:
opcode - the opcode of the local variable instruction to be constructed. This opcode is either MOVE, MOVE/FROM16, MOVE/16, MOVE-WIDE, MOVE-WIDE/FROM16, MOVE-WIDE/16, MOVE-OBJECT, MOVE-OBJECT/FROM16, MOVE-OBJECT/16, CONST/4, CONST/16, CONST, CONST/HIGH16, CONST-WIDE/16, CONST-WIDE/32, CONST-WIDE, CONST-WIDE/HIGH16.
destinationRegister - the destination register.
var - the operand of the instruction to be constructed. This operand is the index of a local variable.
Method Detail

setOpcode

public void setOpcode(int opcode)
Sets the opcode of this instruction.

Parameters:
opcode - the new instruction opcode. This opcode is either MOVE, MOVE/FROM16, MOVE/16, MOVE-WIDE, MOVE-WIDE/FROM16, MOVE-WIDE/16, MOVE-OBJECT, MOVE-OBJECT/FROM16, MOVE-OBJECT/16, CONST/4, CONST/16, CONST, CONST/HIGH16, CONST-WIDE/16, CONST-WIDE/32, CONST-WIDE, CONST-WIDE/HIGH16.

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.
