  • Method Details

    • load

      public void load(InputStream is, int amount) throws IOException
      Loads data into this byte sequence from the given input stream
      Parameters:
      is - the input stream to read bytes from
      amount - the number of bytes to read from the stream
      Throws:
      IOException - if an error occurs reading from the stream

    • getLength

      public int getLength()
      Description copied from interface: ByteSequence
      Returns the length of available bytes.
      Specified by:
      getLength in interface ByteSequence
      Returns:
      the length of the sequence of bytes

    • getByte

      public byte getByte(int index)
      Description copied from interface: ByteSequence
      Returns the byte at the given index. The index must between 0 and the extended length.
      Specified by:
      getByte in interface ByteSequence
      Parameters:
      index - the index in the byte sequence to retrieve a byte value
      Returns:
      the byte at the given index

    • hasAvailableBytes

      public boolean hasAvailableBytes(int index, int length)
      Description copied from interface: ByteSequence
      A convenience method for checking if this sequence can provide a range of bytes from some offset.
      Specified by:
      hasAvailableBytes in interface ByteSequence
      Parameters:
      index - the index of the start of the range to check for available bytes
      length - the length of the range to check for available bytes
      Returns:
      true if bytes are available for the given range

    • getBytes

      public byte[] getBytes(int index, int length)
      Description copied from interface: ByteSequence
      Returns a byte array containing the bytes from the given range.
      Specified by:
      getBytes in interface ByteSequence
      Parameters:
      index - the start index of the range to get bytes
      length - the number of bytes to get
      Returns:
      a byte array containing the bytes from the given range
