Method Detail

initialize

public void initialize(Properties params)
                throws CacheAcquireException

Lyfe-cycle method to allow custom initialization of cache implementations.

Specified by:

initialize in interface Cache<K,V>

Overrides:

initialize in class AbstractBaseCache<K,V>

Parameters:

params - Parameters to initialize the cache (e.g. name, capacity).

Throws:

CacheAcquireException - If cache can not be initialized.

initialize

public void initialize(String implementation,
                       Properties params)
                throws CacheAcquireException

Normally called to initialize JcsCache. To be able to test the method without having org.apache.jcs.JCS implementation, it can also be called with a test implementations classname.

Parameters:

implementation - Cache implementation classname to initialize.

params - Parameters to initialize the cache (e.g. name, capacity).

Throws:

CacheAcquireException - If cache can not be initialized.

getType

public String getType()

Indicates the type of this cache.

Returns:

The cache type.
