T - the type this renderer knows how to presentpublic abstract static class Grid.AbstractRenderer<T> extends Grid.AbstractGridExtension implements Renderer<T>
Grid renderers.
This class currently extends the AbstractExtension superclass, but this
fact should be regarded as an implementation detail and subject to change
in a future major or minor Vaadin revision.ClientConnector.AttachEvent, ClientConnector.AttachListener, ClientConnector.ConnectorErrorEvent, ClientConnector.DetachEvent, ClientConnector.DetachListener| Modifier | Constructor and Description |

This is a helper method that can be invoked by an
encode(T) override if serializing a value of
type other than the presentation type
is desired. For instance, a Renderer<Date> could first turn a
date value into a formatted string and return
encode(dateString, String.class).
