Constructor Detail

• SliceDataGeom

  public SliceDataGeom​(FloatingCoord[] sliceCoords,
                       java.lang.String variantName)

  Constructor. The supplied array of coordinates should contain an element for each of the data position coordinates, but some of those elements may be null, to indicate that no positioning is done in that dimension. Coordinates read into a data position array in the corresponding dimensions will be given as NaNs.

  Parameters:

  sliceCoords - per-data dimension array of coords, some elements may be null

  variantName - variant name

Method Detail

• getDataDimCount

  public int getDataDimCount​()

  Description copied from interface: DataGeom
  Returns the dimensionality of the plot surface's plot space.

  Specified by:

  getDataDimCount in interface DataGeom

  Returns:

  number of elements in data space coordinate array

• hasPosition

  public boolean hasPosition​()

  Returns false.

  Specified by:

  hasPosition in interface DataGeom

  Returns:

  true iff this geom represents point positions

• getVariantName

  public java.lang.String getVariantName​()

  Description copied from interface: DataGeom
  Returns a label for this DataGeom. It may be used to distinguish from other geoms used in the same plot type, so for instance call it "Cartesian" or "Polar" rather than "Plane" if it's X,Y.

  Specified by:

  getVariantName in interface DataGeom

  Returns:

  user-directed input coordinate type name

• getPosCoords

  public Coord[] getPosCoords​()

  Returns an array of the non-null coords.

  Specified by:

  getPosCoords in interface DataGeom

  Returns:

  coordinate quantity array for this geometry

• readDataPos

  public boolean readDataPos​(Tuple tuple,
                             int ic,
                             double[] dpos)

  Description copied from interface: DataGeom
  Determines the positional coordinates in data space for a supplied tuple.

  A parameter supplies the index of the field in the tuple at which the positional coordinate(s) can be found. Each position is represented by DataGeom.getPosCoords() columns of the tuple. By convention positions are at the start of the tuple, so if there is one position in the tuple it will be at icol=0, and there are multiple positions the N'th one will be at icol=N*getPosCoords().

  An array of (at least) DataGeom.getDataDimCount() elements is supplied, and on success the data space coordinate values are written into it.

  Specified by:

  readDataPos in interface DataGeom

  Parameters:

  tuple - coordinate tuple

  ic - column index in tuple at which the positional information starts

  dpos - array into which data space coordinates are written

  Returns:

  true iff conversion was successful

• hashCode

  public int hashCode​()

  Overrides:

  hashCode in class java.lang.Object

• equals

  public boolean equals​(java.lang.Object o)

  Overrides:

  equals in class java.lang.Object
