Constructor Detail

IMethodRefForm

public IMethodRefForm(int opcode,
                      java.lang.String name,
                      int[] rewrite)

Constructs a new instance with the specified opcode, name, operandType and rewrite.

Parameters:

opcode - index corresponding to the opcode's value.

name - String printable name of the opcode.

rewrite - Operand positions (which will later be rewritten in ByteCodes) are indicated by -1.

Method Detail

getOffset

protected int getOffset(OperandManager operandManager)

Specified by:

getOffset in class ReferenceForm

getPoolID

protected int getPoolID()

Specified by:

getPoolID in class ReferenceForm

setByteCodeOperands

public void setByteCodeOperands(ByteCode byteCode,
                                OperandManager operandManager,
                                int codeLength)
                         throws Pack200Exception

Description copied from class: ByteCodeForm

Sets the rewrite of the byteCode.

Overrides:

setByteCodeOperands in class ReferenceForm

Parameters:

byteCode - ByteCode to be updated (!)

operandManager - OperandTable from which to draw info

codeLength - Length of bytes (excluding this bytecode) from the beginning of the method. Used in calculating padding for some variable-length bytecodes (such as lookupswitch, tableswitch).

Throws:

Pack200Exception - if a type is not supported or an index not in the range [0, Integer.MAX_VALUE].
