Constructor Detail
CodeAttribute
public CodeAttribute(ConstPool cp, int stack, int locals, byte[] code, ExceptionTable etable)(Code)
Constructs a Code_attribute.
Parameters:
  cp - constant pool table
Parameters:
  stack - max_stack
Parameters:
  locals - max_locals
Parameters:
  code - code[]
Parameters:
  etable - exception_table[]



CodeAttribute
CodeAttribute(ConstPool cp, int name_id, DataInputStream in) throws IOException(Code)




Method Detail
computeMaxStack
public int computeMaxStack() throws BadBytecode(Code)
Computes the maximum stack size and sets max_stack to the computed size.
throws:
  BadBytecode - if this method fails in computing. the newly computed value of max_stack



copy
public AttributeInfo copy(ConstPool newCp, Map classnames) throws RuntimeCopyException(Code)
Makes a copy. Class names are replaced according to the given Map object.
Parameters:
  newCp - the constant pool table used by the new copy.
Parameters:
