Constructor Detail

VarInsnNode

public VarInsnNode(int opcode,
                   int var)

Visits a local variable instruction. A local variable instruction is an instruction that loads or stores the value of a local variable.

Parameters:

opcode - the opcode of the local variable instruction to be constructed. This opcode must be ILOAD, LLOAD, FLOAD, DLOAD, ALOAD, ISTORE, LSTORE, FSTORE, DSTORE, ASTORE or RET.

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 must be ILOAD, LLOAD, FLOAD, DLOAD, ALOAD, ISTORE, LSTORE, FSTORE, DSTORE, ASTORE or RET.

accept

public void accept(CodeVisitor 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.
