      public int getLength()
      Gets the length of the EH Frame Header.
      Returns:
      the length of this frame header.

    • getEh_FrameVersion

      public int getEh_FrameVersion()
      Gets the version for this program's eh frame.
      Returns:
      the version indicator.

    • getEh_FrameDescEntryCntEncoding

      public int getEh_FrameDescEntryCntEncoding()
      Gets the eh frame description entry count.
      Returns:
      the description entry count.

    • getEh_FramePtrEncoding

      public int getEh_FramePtrEncoding()
      Gets the eh frame pointer encoding.
      Returns:
      the pointer encoding.
