  • Method Details

    • reset

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

    • writeByte

      public void writeByte(byte b)
      Description copied from interface: DataWriter
      Writes one byte to the stream.
      Specified by:
      writeByte in interface DataWriter
      Parameters:
      b - Byte to write.

    • writeData

      public void writeData(byte[] bytes)
      Description copied from interface: DataWriter
      Writes number of bytes in byte range and actual data to the stream. The size of range must not exceed value returned from DataWriter.getMaxCount() method.
      Specified by:
      writeData in interface DataWriter
      Parameters:
      bytes - Bytes to write.

    • writeString

      public void writeString(String str)
      Description copied from interface: DataWriter
      Writes number of characters in string and actual content of string to the data stream. The length of string must not exceed value returned from DataWriter.getMaxCount() method.
      Specified by:
      writeString in interface DataWriter
      Parameters:
      str - String to write.

    • writeRaw

      public void writeRaw(byte[] bytes)
      Description copied from interface: DataWriter
      Writes only the content of byte range to the data stream. Unlike the DataWriter.writeData(byte[]), this method doesn't store number of bytes as a size marker. It's up to you, how you determine the size of sequence during the data reading.
      Specified by:
      writeRaw in interface DataWriter
      Parameters:
      bytes - Data bytes.

    • writeCount

      public boolean writeCount(int count)
      Description copied from interface: DataWriter
      Writes a count to the stream in optimized binary format. The count parameter must be less or equal than value returned from DataWriter.getMaxCount() method. You should prefer this method for counter-type values over the writing 32-bit or 64-bit values to the stream, because it usually produces a shorter byte streams. For example, if count value is lesser than 128, then just one byte is serialized.
      Specified by:
      writeCount in interface DataWriter
      Parameters:
      count - Count value to write.
      Returns:
      whether write succeeded

    • getSerializedData

      public byte[] getSerializedData()
      Description copied from interface: DataWriter
      Returns serialized data.
      Specified by:
      getSerializedData in interface DataWriter
      Returns:
      Serialized data.

    • getMaxCount

      public int getMaxCount()
      Description copied from interface: DataWriter
      Returns maximum supported value which can be serialized as a counter. The returned value is the same for all supported platforms and CPU architectures.
      Specified by:
      getMaxCount in interface DataWriter
      Returns:
      Maximum count value.
