public interface ILcdCache

This interface defines methods for classes that can contain cache information. Clients can then use this mechanism to store their own information in objects that implement the interface.

Cached objects identified by their own keys. Each key must therefore be unique.

Method Summary

Modifier and Type	Method and Description
void	clearCache() Clears the cache.
java.lang.Object	getCachedObject(java.lang.Object aKey) Looks up and returns the cached Object corresponding to the given key.
void	insertIntoCache(java.lang.Object aKey, java.lang.Object aObject) Inserts a cache Object corresponding to the given key Object.
java.lang.Object	removeCachedObject(java.lang.Object aKey) Looks up and removes the cached Object corresponding to the given key.

Method Detail

insertIntoCache

void insertIntoCache(java.lang.Object aKey,
                     java.lang.Object aObject)

Inserts a cache Object corresponding to the given key Object.

Parameters:

aKey - the key Object that will be used to identify the Object. The key must therefore be a unique identifier, typically the caller itself: insertIntoCache(this, ...).

aObject - the Object to be cached.

getCachedObject

java.lang.Object getCachedObject(java.lang.Object aKey)

Looks up and returns the cached Object corresponding to the given key.

Parameters:

aKey - the key Object that was used for storing the cache Object.

Returns:

the cached Object, or null if there is no Object corresponding to the given key.

removeCachedObject

java.lang.Object removeCachedObject(java.lang.Object aKey)

Looks up and removes the cached Object corresponding to the given key.

Parameters:

aKey - the key Object that was used for storing the cache Object.

Returns:

the cached Object, or null if there was no Object corresponding to the given key.

clearCache

void clearCache()

Clears the cache.
