      Parameters:
      table - a flattened sequence of (startPC, lineNumber) pairs
    • getSize

      public int getSize()
      Specified by:
      getSize in class ClassWriter.Element
      Returns:
      the number of bytes that will be generated.
    • copyInto

      public int copyInto(byte[] buf, int offset) throws IllegalArgumentException
      Description copied from class: ClassWriter.Element
      Copy the bytes into 'buf' at offset 'offset'.
      Specified by:

    • makeRawTable

      public static int[] makeRawTable(int[] newLineMap) throws IllegalArgumentException
      Parameters:
      newLineMap - an array indexed by bytecode offset, mapping each bytecode offset to its line number (or 0 if there is no line or it's not known)
      Returns:
      the line numbers in "raw" format, a flattened sequence of (startPC, lineNumber) pairs
