  • Method Details

    • reset

      public void reset()
      Description copied from interface: DataReader
      Resets data reader to its initial state.
      Specified by:
      reset in interface DataReader

    • remainingSize

      public int remainingSize()
      Description copied from interface: DataReader
      Returns remaining size available in the stream.
      Specified by:
      remainingSize in interface DataReader
      Returns:
      Remaining size.

    • currentOffset

      public int currentOffset()
      Description copied from interface: DataReader
      Returns current reading offset.
      Specified by:
      currentOffset in interface DataReader
      Returns:
      Current reading offset.

    • canReadSize

      public boolean canReadSize(int size)
      Description copied from interface: DataReader
      Returns true if it's possible to read at least |size| of bytes from stream.
      Specified by:
      canReadSize in interface DataReader
      Parameters:
      size - Byte size.
      Returns:
      True if reader can read next bytes.

    • skipBytes

      public boolean skipBytes(int size)
      Description copied from interface: DataReader
      Skips required number of bytes in the stream. Returns false, if there's not enough bytes left.
      Specified by:
      skipBytes in interface DataReader
      Parameters:
      size - Byte size.
      Returns:
      True if skip was successful.

    • readData

      public byte[] readData(int expectedSize)
      Description copied from interface: DataReader
      Reads a data object into output byte array.
      Specified by:
      readData in interface DataReader
      Parameters:
      expectedSize - Expected byte array size or 0 for any size.
      Returns:
      Read data.

    • readString

      public String readString()
      Description copied from interface: DataReader
      Reads a string object into output byte array.
      Specified by:
      readString in interface DataReader

      Specified by:
      readRaw in interface DataReader
      Parameters:
      size - Byte size.
      Returns:
      Read bytes.

    • readByte

      Description copied from interface: DataReader
      Reads one byte into output byte array.
      Specified by:
      readByte in interface DataReader
      Returns:
      Read byte.

    • readCount

      public Integer readCount()
      Description copied from interface: DataReader
      Returns count from data stream.
      Specified by:
      readCount in interface DataReader
      Returns:
      Count.
