Method Detail

performSingleOperation

public void performSingleOperation(net.sf.ehcache.writer.CacheWriter cacheWriter,
                                   SerializationStrategy serializationStrategy)
                            throws ClassNotFoundException,
                                   IOException

Description copied from interface: SingleAsyncOperation

Perform this operation as a single execution with the provided cache writer

Specified by:

performSingleOperation in interface SingleAsyncOperation

Parameters:

cacheWriter - the cache writer this operation should be performed upon

serializationStrategy - the strategy that should be used to serialize and deserialize, if needed

Throws:

ClassNotFoundException

IOException

getKey

public Object getKey(SerializationStrategy serializationStrategy)
              throws IOException,
                     ClassNotFoundException

Description copied from interface: SingleAsyncOperation

Retrieves the key for this operation.

Specified by:

getKey in interface SingleAsyncOperation

Parameters:

serializationStrategy - the serialization strategy that should be used to create the key

Returns:

this operation's key

Throws:

IOException

ClassNotFoundException

createElement

public net.sf.ehcache.Element createElement(SerializationStrategy serializationStrategy)
                                     throws ClassNotFoundException,
                                            IOException

Throws:

ClassNotFoundException

IOException

createBatchOperation

public BatchAsyncOperation createBatchOperation(List<SingleAsyncOperation> operations,
                                                SerializationStrategy serializationStrategy)
                                         throws ClassNotFoundException,
                                                IOException

Description copied from interface: SingleAsyncOperation

Creates a batch operation that corresponds to the operation type of this single async operation.

This batch operation will not be stored in the async queue anymore and is solely used for structuring. The data from the single operation will already be processed in the final form that will be expected by the CacheWriter that will be used to execute the batch operation.

Specified by:

createBatchOperation in interface SingleAsyncOperation

Parameters:

operations - the single operations that need to be regrouped in the batch operation

serializationStrategy - the serialization strategy that should be used to create the data for the batch operation

Returns:

the created batch operation

Throws:

ClassNotFoundException

IOException

getCreationTime

public long getCreationTime()

Description copied from interface: SingleAsyncOperation

Retrieves the moment when the operation was created.

Specified by:

getCreationTime in interface SingleAsyncOperation

Returns:

the creation time in milliseconds
