Overrides org.apache.commons.compress.harmony.unpack200.bytecode.forms.ByteCodeForm.fixUpByteCodeTargets.

The ByteCodeForm knows how to fix up a bytecode if it needs to be fixed up because it holds a Label bytecode.

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).

Implements abstract org.apache.commons.compress.harmony.unpack200.bytecode.forms.ByteCodeForm.setByteCodeOperands.

When passed a byteCode, an OperandTable and a SegmentConstantPool, this method will set the rewrite of the byteCode appropriately.

The ByteCodeForm knows how to fix up a bytecode if it needs to be fixed up because it holds a Label bytecode.

Parameters
byteCode:ByteCode

a ByteCode to be fixed up

codeAttribute:CodeAttribute

a CodeAttribute used to determine how the ByteCode should be fixed up.

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

Implements abstract org.apache.commons.compress.harmony.unpack200.bytecode.forms.ByteCodeForm.setByteCodeOperands.

Doc from org.apache.commons.compress.harmony.unpack200.bytecode.forms.ByteCodeForm.setByteCodeOperands.

When passed a byteCode, an OperandTable and a SegmentConstantPool, this method will set the rewrite of the byteCode appropriately.

Parameters
byteCode:ByteCode

ByteCode to be updated (!)

operandManager:OperandManager

OperandTable from which to draw info

codeLength:int

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).
