getByOpcode
public static final InsnNode getByOpcode(int opcode)
uses the constructor instead.
Returns the
InsnNode
corresponding to the given opcode.
opcode
- an instruction opcode.
- the
InsnNode
corresponding to the given opcode.
getType
public int getType()
Returns the type of this instruction.
- getType in interface AbstractInsnNode
- the type of this instruction, i.e. one the constants defined in
this class.
