Class Overview

The state for an XYItemRenderer.

Summary

Fields
public Line2D workingLine A line object that the renderer can reuse to save instantiating a lot of objects.
Public Constructors
XYItemRendererState(PlotRenderingInfo info)
Creates a new state.
Public Methods
void endSeriesPass(XYDataset dataset, int series, int firstItem, int lastItem, int pass, int passCount)
This method is called by the XYPlot when it ends a pass through the (visible) items in a series.
int getFirstItemIndex()
Returns the first item index (this is updated with each call to startSeriesPass(XYDataset, int, int, int, int, int).
int getLastItemIndex()
Returns the last item index (this is updated with each call to startSeriesPass(XYDataset, int, int, int, int, int).
boolean getProcessVisibleItemsOnly()
Returns the flag that controls whether the plot passes all data items in each series to the renderer, or just the visible items.
void setProcessVisibleItemsOnly(boolean flag)
Sets the flag that controls whether the plot passes all data items in each series to the renderer, or just the visible items.
void startSeriesPass(XYDataset dataset, int series, int firstItem, int lastItem, int pass, int passCount)
This method is called by the XYPlot when it starts a pass through the (visible) items in a series.

public Line2D workingLine

A line object that the renderer can reuse to save instantiating a lot of objects.

Public Constructors

public XYItemRendererState (PlotRenderingInfo info)

Creates a new state.

Parameters
info the plot rendering info.

Public Methods

public void endSeriesPass (XYDataset dataset, int series, int firstItem, int lastItem, int pass, int passCount)

This method is called by the XYPlot when it ends a pass through the (visible) items in a series. The default implementation does nothing, but you can override this method to implement specialised behaviour.

Parameters
dataset the dataset.
series the series index.
firstItem the index of the first item in the series.
lastItem the index of the last item in the series.
pass the pass index.
passCount the number of passes.

public int getFirstItemIndex ()

Returns the first item index (this is updated with each call to startSeriesPass(XYDataset, int, int, int, int, int).

Returns
  • The first item index.

public int getLastItemIndex ()

Returns the last item index (this is updated with each call to startSeriesPass(XYDataset, int, int, int, int, int).

Returns
  • The last item index.

public boolean getProcessVisibleItemsOnly ()

Returns the flag that controls whether the plot passes all data items in each series to the renderer, or just the visible items. The default value is true.

Returns
  • A boolean.

public void setProcessVisibleItemsOnly (boolean flag)

Sets the flag that controls whether the plot passes all data items in each series to the renderer, or just the visible items.

Parameters
flag the new flag value.

public void startSeriesPass (XYDataset dataset, int series, int firstItem, int lastItem, int pass, int passCount)

This method is called by the XYPlot when it starts a pass through the (visible) items in a series. The default implementation records the first and last item indices - override this method to implement additional specialised behaviour.

Parameters
dataset the dataset.
series the series index.
firstItem the index of the first item in the series.
lastItem the index of the last item in the series.
pass the pass index.
passCount the number of passes.
