Method Summary

BatchAsyncOperation	createBatchOperation(List<SingleAsyncOperation> operations, SerializationStrategy serializationStrategy) Creates a batch operation that corresponds to the operation type of this single async operation.
long	getCreationTime() Retrieves the moment when the operation was created.
Object	getKey(SerializationStrategy serializationStrategy) Retrieves the key for this operation.
void	performSingleOperation(net.sf.ehcache.writer.CacheWriter cacheWriter, SerializationStrategy serializationStrategy) Perform this operation as a single execution with the provided cache writer

Method Detail

performSingleOperation

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

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

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

createBatchOperation

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

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.

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

getKey

Object getKey(SerializationStrategy serializationStrategy)
              throws IOException,
                     ClassNotFoundException

Retrieves the key for this operation.

Parameters:

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

Returns:

this operation's key

Throws:

IOException

ClassNotFoundException

getCreationTime

long getCreationTime()

Retrieves the moment when the operation was created.

Returns:

the creation time in milliseconds
