Constructor Detail

InvokeStaticInstruction

public InvokeStaticInstruction(ConstPool constPool,
                               int opcode,
                               int offset,
                               int methodIndex)

Constructs an InvokeStaticInstruction.

Parameters:

constPool - The constant pool associated with the class.

opcode - The opcode of the instruction.

offset - The bytecode offset of the instruction.

methodIndex - The constant pool index for the method reference.

Method Detail

getMethodIndex
