Deprecated.

Apache Commons Collections version 3.x is being deprecated from AEMaaCS. The upgraded version 4.4 of Commons Collections is already included as replacement. Customers are advised to upgrade to this version of the library. Please note: the package name was changed to org.apache.commons.collections4. Further note that there are AEM APIs currently exposing the old collections classes; these will be updated in upcoming releases.

Decorates another SortedMap to validate that additions match a specified predicate.

This map exists to provide validation for the decorated map. It is normally created to decorate an empty map. If an object cannot be added to the map, an IllegalArgumentException is thrown.

One usage would be to ensure that no null keys are added to the map.

SortedMap map = PredicatedSortedSet.decorate(new TreeMap(), NotNullPredicate.INSTANCE, null);

Note that PredicatedSortedMap is not synchronized and is not thread-safe. If you wish to use this map from multiple threads concurrently, you must use appropriate synchronization. The simplest approach is to wrap this map using Collections.synchronizedSortedMap(java.util.SortedMap<K, V>). This class may throw exceptions when accessed by concurrent threads without synchronization.

This class is Serializable from Commons Collections 3.1.

Since:

Commons Collections 3.0

Method Details

decorate

public static SortedMap decorate(SortedMap map,
 Predicate keyPredicate,
 Predicate valuePredicate)

Deprecated.

Factory method to create a predicated (validating) sorted map.

If there are any elements already in the list being decorated, they are validated.

Parameters:

map - the map to decorate, must not be null

keyPredicate - the predicate to validate the keys, null means no check

valuePredicate - the predicate to validate to values, null means no check

Throws:

IllegalArgumentException - if the map is null
