| PersistentMap | | public interface PersistentMap extends Map(Code) | | This interface defines a persistent map. The entries in a persistent
map can be loaded from or saved to persistent storage.
|
| Method Summary | |
| public boolean | isModified()
Indicates whether modifications need to be saved currently. | | public void | load()
Loads the map from persistent store. | | public int | maxKeyLength()
Retrieves the information about the maximum string length of key
entries. | | public void | store()
Stores the map in persistent store. |
| isModified | | public boolean isModified()(Code) | | Indicates whether modifications need to be saved currently.
true, if there are non-saved modifications, otherwise false. |
| load | | public void load() throws IOException(Code) | | Loads the map from persistent store. The data needed to define
the persistent store is usually passed as parameters to the
constructor of the implementing class.
throws:
IOException - problems while loading the map |
| maxKeyLength | | public int maxKeyLength() throws IOException(Code) | | Retrieves the information about the maximum string length of key
entries.
