Package com.vaadin.v7.data.util.filter

Class Or

java.lang.Object

com.vaadin.v7.data.util.filter.AbstractJunctionFilter

com.vaadin.v7.data.util.filter.Or

All Implemented Interfaces:

Container.Filter, Serializable

@Deprecated
public final class Or
extends AbstractJunctionFilter

Deprecated.

As of 8.0, the whole filtering feature is integrated into DataProvider. For in-memory case (ListDataProvider), use predicates as filters. For back-end DataProviders, filters are specific to the implementation.

A compound Container.Filter that accepts an item if any of its filters accept the item. If no filters are given, the filter should reject all items. This filter also directly supports in-memory filtering when all sub-filters do so.

Since:

6.6

appliesToProperty

public boolean appliesToProperty(Object propertyId)

Deprecated.

Returns true if a change in the named property may affect the filtering result. If some of the sub-filters are not in-memory filters, true is returned. By default, all sub-filters are iterated to check if any of them applies. If there are no sub-filters, true is returned as an empty Or rejects all items.

Specified by:

appliesToProperty in interface Container.Filter

Overrides:

appliesToProperty in class AbstractJunctionFilter

Returns:

true if the filtering result may/does change based on changes to the property identified by propertyId
