Interface ILcdMultiKeyCache

All Superinterfaces:

ILcdMultiKeyMap<Object,Object>, Map<Object,Object>

public interface ILcdMultiKeyCache
extends ILcdMultiKeyMap<Object,Object>

Multi-key cache used by the view to cache data. It allows any type of key and value to be stored in the cache. A multi-key cache is a multi-key map that takes ownership of the stored values. The cache itself can remove entries when needed. See ILcdMultiKeyMap for a detailed description of the workings of a multi-key map.

Method Details

getBranch

ILcdMultiKeyCache getBranch(Object[] aKeys)

Description copied from interface: ILcdMultiKeyMap

Returns the branch that is associated with the given key, or null if the branch does not exist.

Specified by:

getBranch in interface ILcdMultiKeyMap<Object,Object>

Parameters:

aKeys - the key

Returns:

the branch associated with the given key, can be null if a branch does not exist.

getOrCreateBranch

ILcdMultiKeyCache getOrCreateBranch(Object[] aKeys)

Description copied from interface: ILcdMultiKeyMap

Creates and returns a new branch for the given key. A new branch (or sub-branch) is only created when necessary.

Specified by:

getOrCreateBranch in interface ILcdMultiKeyMap<Object,Object>

Parameters:

aKeys - the key

Returns:

the branch associated with the given key. This method never returns null.

branchEntrySet

Set<? extends Map.Entry<Object,? extends ILcdMultiKeyCache>> branchEntrySet()

Description copied from interface: ILcdMultiKeyMap

Gets the entries of this branch's branch map.

Specified by:

branchEntrySet in interface ILcdMultiKeyMap<Object,Object>

Returns:

the branch entry set

branchValues

Collection<? extends ILcdMultiKeyCache> branchValues()

Description copied from interface: ILcdMultiKeyMap

Gets the values of this branch's leaf map.

Specified by:

branchValues in interface ILcdMultiKeyMap<Object,Object>

Returns:

the branch value set
