Examples of org.apache.sling.api.resource.PersistableValueMap

org.apache.sling.api.resource.PersistableValueMap
The PersistableValueMap is an extension of the {@link ValueMap} which allows to modify andpersist the properties.
Note, that each time you call {@link Resource#adaptTo(Class)}you get a new map instance which does not share modified properties with other representations.
A PersistableValueMap might not support deep reading of values. @deprecated Use the {@link ModifiableValueMap} instead.
