Detailed Description

A container that holds objects able to respond to queries specialized for particular vtkCellMetadata types.

vtkCellGridResponders holds a list of objects statically registered to the vtkCellMetadata subclass. These objects respond to queries for information (e.g., a bounding box) or processing (e.g., rendering, picking, generating isocontours) for one cell type (and subclasses of that cell type if no more specific responder is registered).

Application code (such as a plugin) can register subclasses of vtkCellGridResponse which accept the API of a particular vtkCellGridQuery for that cell type. Then, when a query is passed to the cell, this collection will identify matching responders for the query and invoke them until one returns true (indicating success). Multiple matches can exist as a responder can be registered to a common base cell class and/or to handle common base query classes.

If a given cell type cannot respond to a query, its superclasses are asked to respond. If no superclass can respond to the query, then query's superclasses are searched for responders.

Because queries can be registered to cell types at any time, existing cell types can be extended to support new features by additional libraries.
