Constructor Detail

GuiPointCloud

public GuiPointCloud(TableCloud[] tclouds,
                     uk.ac.starlink.ttools.plot2.data.DataStore baseDataStore,
                     BoundedRangeModel progModel)

Constructor.

Parameters:

tclouds - per-table position collections

baseDataStore - data store supplying the position data

progModel - progress bar model; if non-null, iteration over the points will update it

Method Detail

getTableClouds

public TableCloud[] getTableClouds()

Returns the TableClouds aggregated by this point cloud.

Returns:

table cloud array

createGuiDataStore

public GuiDataStore createGuiDataStore()

Returns a data store that can be used for iterating over this point cloud. This data store adds value to the supplied base data store: it checks for thread interruptions and reports progress as appropriaate.

Returns:

data store

createDataPosSupplier

public java.util.function.Supplier<uk.ac.starlink.ttools.plot2.CoordSequence> createDataPosSupplier(uk.ac.starlink.ttools.plot2.data.DataStore dataStore)

Returns an iterable over the point cloud.

Parameters:

dataStore - data store

Returns:

iterable over data positions
