setByteCodeOperands
public void setByteCodeOperands(ByteCode byteCode, OperandManager operandManager, int codeLength) throws Pack200Exception Description copied from class:ByteCodeFormSets the rewrite of the byteCode.- Specified by:
setByteCodeOperandsin classByteCodeForm- Parameters:
byteCode- ByteCode to be updated (!)operandManager- OperandTable from which to draw infocodeLength- 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].
-
setNestedEntries
protected void setNestedEntries(ByteCode byteCode, OperandManager operandManager, int offset) throws Pack200Exception Sets the nested entries.- Parameters:
byteCode- byte codes.operandManager- Operand manager.offset- offset.- Throws:
Pack200Exception- if support for a type is not supported or the offset not in the range [0,Integer.MAX_VALUE].
