  • Method Details

    • getOffset

      int getOffset()
      Get data chunk offset.
      Returns:
      data chunk offset

    • getLength

      int getLength()
      Get data chunk length
      Returns:
      data chunk length

    • getEstimatedSize

      int getEstimatedSize()
      Get estimated size in bytes.
      Returns:
      estimated size in bytes

    • getCompressionFactor

      double getCompressionFactor()
      Get compression factor. 1 means no compression.
      Returns:
      the compression factor

    • isCompressed

      boolean isCompressed()
      Check if chunk is in compressed form.
      Returns:
      true if chunk is in compressed form, false otherwise

    • getDataType

      TimeSeriesDataType getDataType()
      Get data type.
      Returns:
      the data type

    • stream

      Stream<P> stream(TimeSeriesIndex index)
      Get a point stream.
      Parameters:
      index - the time series index
      Returns:
      a point stream

    • iterator

      Iterator<P> iterator(TimeSeriesIndex index)
      Get a point iterator.
      Parameters:
      index - the time series index
      Returns:
      a point iterator

    • tryToCompress

      A tryToCompress()
      Try to compress the chunk.
      Returns:
      the compressed chunk or itself if compression is not efficient enough

    • splitAt

      DataChunk.Split<P,A> splitAt(int splitIndex)
      Split the chunk in two parts.
      Parameters:
      splitIndex - the split index
      Returns:
      both chunks

    • append

      A append(A otherChunk)
      Append the chunk with the one given in argument, and return the result. "This" dataChunk and the one in argument remain unchanged. The two chunks have to be successive, i.e : this.getOffset() + this.length() = otherChunk.getOffset()
      Parameters:
      otherChunk - : the chunk to append with this object. It has to be the same implementation as this object.
      Returns:

    • writeJson

      void writeJson(com.fasterxml.jackson.core.JsonGenerator generator)
      Serialize this data chunk to json.
      Parameters:
      generator - a json generator (jackson)
      Throws:
      IOException - in case of json writing error

    • create

      static DoubleDataChunk create(int offset, double[] values)

    • create

      static DoubleDataChunk create(double... values)

      static StringDataChunk create(int offset, String[] values)

    • create

      static StringDataChunk create(String... values)

    • writeJson

      static void writeJson(com.fasterxml.jackson.core.JsonGenerator generator, List<? extends DataChunk> chunks)
      Serialize a chunk list to json
      Parameters:
      generator - a json generator (jackson)
      chunks - the chunk list

    • toJson

      String toJson()

    • parseFieldName

      static void parseFieldName(com.fasterxml.jackson.core.JsonParser parser, DataChunk.JsonParsingContext context) throws IOException
