Method Details

accept

public void accept(MethodVisitor mv)
Makes the given visitor visit this instruction.
Overrides:
accept in interface AbstractInsnNode
Parameters:
mv - a method visitor.

getByOpcode

public static final InsnNode getByOpcode(int opcode)

Deprecated. uses the constructor instead.

Returns the InsnNode corresponding to the given opcode.
Parameters:
opcode - an instruction opcode.
Returns:
the InsnNode corresponding to the given opcode.

getType

public int getType()
Returns the type of this instruction.
Overrides:
getType in interface AbstractInsnNode
Returns:
the type of this instruction, i.e. one the constants defined in this class.
