Class StorageMap

java.lang.Object

com.google.gwt.storage.client.StorageMap

public static class StorageMap
extends Object

Exposes the local/session Storage as a standard Map<String, String>.

Experimental API: This API is still under development and is subject to change.

The following characteristics are associated with this Map:

1. Mutable - All 'write' methods (#put(String, String), #putAll(Map), #remove(Object), #clear(), Entry#setValue(Object)) operate as intended;
2. remove() on Iterators - All remove() operations on available Iterators (from #keySet(), #entrySet() and #values()) operate as intended;
3. No null values and keys - The Storage doesn't accept keys or values which are null;
4. JavaScriptException instead of NullPointerException - Some Map (or other Collection) methods mandate the use of a NullPointerException if some argument is null (e.g. #remove(Object) remove(null)). this Map emits JavaScriptExceptions instead;
5. String values and keys - All keys and values in this Map are String types.
