Package org.gephi.appearance.spi

Interfaces that define the different ways the appearance of elements can be transformed.

The purpose of transformers is to change the appearance of elements based on user parameters and column's values. There are three types of transformers: simple, ranking and partition. The simple transformer interface is defined in org.gephi.appearance.spi.SimpleTransformer. The ranking and partition transformers are both based on the specific value an element has in a given column. The ranking transformer work with numerical, sorted values (e.g. age, number of followers) and the partition transformer work with categorical values (e.g. community id, gender). The ranking transformer is defined in org.gephi.appearance.spi.RankingTransformer and the partition transformer in org.gephi.appearance.spi.PartitionTransformer. Then, transformers can be associated with user interfaces elements through the implementation of org.gephi.appearance.spi.TransformerUI.

Interface Summary

Interface	Description
PartitionTransformer<E extends Element>	Partition transformer that transforms an element based on a categorical partition column.
RankingTransformer<E extends Element>	Ranking transformer that transforms an element based on a numerical ranking column.
SimpleTransformer<E extends Element>	Basic transformer that takes only an element to transform it.
Transformer	Transformers role is to transform the appearance of elements based on user configuration.
TransformerCategory	Transformer categories are associated with TransformerUI to describe what kind of transformation is performed.
TransformerUI<T extends Transformer>	Defines the user interface associated with a transformer.
