 The interfaces that extend Manipulator to provide specific types of manipulators are:
 
-- [NodesManipulator](http://gephi.org/docs/toolkit/org/gephi/datalab/spi/nodes/NodesManipulator.html) - Defines a context menu action to manipulate one or more selected nodes.
-- [EdgesManipulator](http://gephi.org/docs/toolkit/org/gephi/datalab/spi/edges/EdgesManipulator.html) - Defines a context menu action to manipulate one or more selected edges.
-- [GeneralActionsManipulator](http://gephi.org/docs/toolkit/org/gephi/datalab/spi/general/GeneralActionsManipulator.html) - Defines a general action not related to any specific graph element. [PluginGeneralActionsManipulator](http://gephi.org/docs/toolkit/org/gephi/datalab/spi/general/PluginGeneralActionsManipulator.html) is the same but appears in a plugin button that displays a list of general actions (use this when the tool bar does not have enough space for more general actions).
-- [AttributeValueManipulator](http://gephi.org/docs/toolkit/org/gephi/datalab/spi/values/AttributeValueManipulator.html) - Defines a context menu action that manipulates a single cell data (pair of AttributeRow and AttributeColumn).
-- [AttributeColumnsMergeStrategy](http://gephi.org/docs/toolkit/org/gephi/datalab/spi/columns/merge/AttributeColumnsMergeStrategy.html) - Defines an strategy

 -- [AttributeRowsMergeStrategy](https://javadoc.io/doc/org.gephi/gephi/latest/org/gephi/datalab/spi/rows/merge/AttributeRowsMergeStrategy.html) - A very special type of manipulator that defines strategies for merging rows to be used by a nodes/edges manipulator or other parts (does not have a place in Data Laboratory GUI by itself but it is currently used by MergeNodes manipulator).
 
 Only [AttributeColumnsManipulator](https://javadoc.io/doc/org.gephi/gephi/latest/org/gephi/datalab/spi/columns/AttributeColumnsManipulator.html) is a bit different from `Manipulator` because its workflow is not the same as all the previous manipulators, and therefore provides its unique interface plus a [AttributeColumnsManipulatorUI](https://javadoc.io/doc/org.gephi/gephi/latest/org/gephi/datalab/spi/columns/AttributeColumnsManipulatorUI.html).
