com.vaadin.v7.ui.Table.TableDropCriterion

All Implemented Interfaces:

AcceptCriterion, Serializable

Enclosing class:

Table

Deprecated.

@Deprecated
public abstract static class Table.TableDropCriterion
extends ServerSideCriterion

Lazy loading accept criterion for Table. Accepted target rows are loaded from server once per drag and drop operation. Developer must override one method that decides on which rows the currently dragged data can be dropped.

Initially pretty much no data is sent to client. On first required criterion check (per drag request) the client side data structure is initialized from server and no subsequent requests requests are needed during that drag and drop operation.
