getFilters

public Collection<Container.Filter> getFilters()

Returns an unmodifiable collection of the sub-filters of this composite filter.

Returns:

appliesToProperty

public boolean appliesToProperty(Object propertyId)

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, false is returned - override in subclasses to change this behavior.

Specified by:

appliesToProperty in interface Container.Filter

Returns:

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

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

Overrides:

hashCode in class Object
