Constructor Parameters
| Parameter | Type | Default | Description |
|---|---|---|---|
| code | String | default | The code that groups the Map.Entry. |
| maxSize | int | The maximum key count of a particular code group in memory. Anything beyond this limit will trigger either the evictLogic or the losslessLogic. | |
| evictLogic | BiConsumer<String, Map.Entry<TYPE_KEY, TYPE_VALUE>> | A custom eviction logic. | |
| losslessLogic | ILosslessLogic<TYPE_KEY, TYPE_VALUE> | DefaultLosslessLogic<TYPE_KEY, TYPE_VALUE> | An implementation of ILosslessLogic. |
Proprietary Methods
| Method | Description |
|---|---|
| public function memCacheSize() : int | Returns the size of cache in memory. |
| public function memCachedKeys() : Set<TYPE_KEY> | Returns the keys in memory. |
| public function memCachedValues() : Collection<TYPE_VALUE> | Returns the values in memory. |
DefaultLosslessLogic<TYPE_KEY, TYPE_VALUE>Â Class
An implementation of ILosslessLogic<TYPE_KEY, TYPE_VALUE> that only accepts String as the key and Value that must be tag as Serializable. The work of this class will only start if the maxSize key allocated for memory storage was exceeded. If the key counts is beyond the maxSize indicated, all the key entries that are not used will be serialized to the location defined by the environment variable GCACHE_DIR or if it is not present to your <TMP_DIR>\gcache directory. The extension name of a serialized objects is ser.
Usage
-
Add the following maven dependency to your gosu project:
Property Value Group ID xyz.ronella.gosu Artifact ID gcache Version 1.1.0 Using gradle, this can be added as a dependency entry like the following:
compile group: 'xyz.ronella.gosu', name: 'gcache', version: '1.1.0'
-
On your code, once an instance of ConcurrentLRUCache was created, use it like you are using an instance of a Map.
