  • Method Details

    • getExternalType

      public DataChunk.DataType getExternalType()
      Description copied from interface: DataChunk
      Gets the external data type that values in this chunk are meant to represent. This is the type that the chunk unpacks to if values are packed.
      Specified by:
      getExternalType in interface DataChunk
      Returns:
      the external data type.

    • getScalingScheme

      public ScalingScheme getScalingScheme()
      Description copied from interface: FloatingPointValuedDataChunk
      Gets the scaling scheme. A scaling scheme is used to alter the values of floating point data using some scaling.
      Specified by:
      getScalingScheme in interface FloatingPointValuedDataChunk
      Returns:
      the scaling scheme or null if the chunk data is not scaled.

    • accept

      public void accept(ChunkVisitor visitor)
      Description copied from interface: DataChunk
      Accepts a visitor in this chunk.
      Specified by:
      accept in interface DataChunk
      Parameters:
      visitor - the visitor to accept.

    • getValues

      public int getValues()
      Description copied from interface: DataChunk
      Gets the number of values held by this chunk.
      Specified by:
      getValues in interface DataChunk
      Returns:
      the number of values.

    • getPrimitiveData

      public Object getPrimitiveData()
      Description copied from interface: DataChunk
      Gets the primitive chunk data.
      Specified by:
      getPrimitiveData in interface DataChunk
      Returns:
      the primitive data stored in this chunk.

    • blankCopy

      public DataChunk blankCopy()
      Description copied from interface: DataChunk
      Creates a blank copy of this data chunk.
      Specified by:
      blankCopy in interface DataChunk
      Returns:
      the new blank data chunk. The data values are uninitialized.

    • blankCopyWithValues

      public DataChunk blankCopyWithValues(int values)
      Description copied from interface: DataChunk
      Creates a blank copy of this data chunk with the specified number of data values.
      Specified by:
      blankCopyWithValues in interface DataChunk
      Parameters:
      values - the number of data values in the new blank data chunk.
      Returns:
      the new blank data chunk. The data values are uninitialized.

    • getMissing

      public Double getMissing()
      Gets the missing value. The missing value is used in the primitive data to represent invalid data values.
      Returns:
      the missing value or null if the chunk has no missing value specified.

    • getDoubleData

      public double[] getDoubleData()
      Gets the primitive array used to store data.
      Returns:
      the primitive double data array containing the data.

    • isCompatible

      public boolean isCompatible(DataChunk chunk)
      Description copied from interface: DataChunk
      Checks if this chunk is compatible with another. Compatible chunks share the same primitive data type and other properties.
      Specified by:
      isCompatible in interface DataChunk
      Parameters:
      chunk - the data chunk to check.

    • valueBytes

      public int valueBytes()
      Description copied from interface: DataChunk
      Gets the number of bytes each value uses.
      Specified by:
      valueBytes in interface DataChunk
      Returns:
      the bytes per data value in the primitive data.
