Method Detail

createContinuousDistribution

public abstract IlvContinuousColorDistribution createContinuousDistribution(IlvTreeListModel model,
                                                                            IlvDataColumnInfo column,
                                                                            IlvDataConverter converter)

Chooses and returns a color distribution for a given column of real values in a model of objects.

This color distribution is used in a single rendering only. It can therefore assume that the model columns and contents will not change while it is in use.

Parameters:

model - A tree model with per-node values.

column - A column of the tree model.

converter - A converter from objects to numbers.

createEnumeratedDistribution

public abstract IlvEnumeratedColorDistribution createEnumeratedDistribution(IlvTreeListModel model,
                                                                            IlvDataColumnInfo column,
                                                                            Collection values)

Chooses and returns a color distribution for a given enumerated column in a model of objects.

This color distribution is used in a single rendering only. It can therefore assume that the model columns and contents will not change while it is in use.

Parameters:

model - A tree model with per-node values.

column - A column of the tree model.

values - The set of possible values. Should not contain duplicates.
