    • CodespaceRange

      public CodespaceRange(byte[] startBytes, byte[] endBytes)
      Creates a new instance of CodespaceRange. The length of both arrays has to be the same.
      For one byte ranges startBytes and endBytes define a linear range of values. Double byte values define a rectangular range not a linear range. Examples:
      <00> <20> defines a linear range from 0x00 up to 0x20.
      <8140> to <9FFC> defines a rectangular range. The high byte has to be within 0x81 and 0x9F and the low byte has to be within 0x40 and 0xFC
      Parameters:
      startBytes - start of the range
      endBytes - start of the range

  • Method Details

    • getCodeLength

      public int getCodeLength()
      Returns the length of the codes of the codespace.
      Returns:
      the code length

    • matches

      public boolean matches(byte[] code)
      Returns true if the given code bytes match this codespace range.
      Parameters:
      code - the code bytes to be matched
      Returns:
      true if the given code bytes match this codespace range

    • isFullMatch

      public boolean isFullMatch(byte[] code, int codeLen)
      Returns true if the given number of code bytes match this codespace range.
      Parameters:
      code - the code bytes to be matched
      codeLen - the code length to be used for matching
      Returns:
      true if the given number of code bytes match this codespace range
