Constructor Detail

WriteOperation

public WriteOperation(K k,
                      V v)

Create a new write operation for a particular element

WriteOperation

public WriteOperation(K k,
                      V v,
                      long creationTime)

Create a new write operation for a particular element and creation time

Method Detail

performSingleOperation

public void performSingleOperation(CacheLoaderWriter<K,V> cacheWriter)
                            throws java.lang.Exception

Description copied from interface: SingleOperation

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

Specified by:

performSingleOperation in interface SingleOperation<K,V>

Throws:

java.lang.Exception

createBatchOperation

public BatchOperation<K,V> createBatchOperation(java.util.List<SingleOperation<K,V>> operations)

Description copied from interface: SingleOperation

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

This batch operation will not be stored in the 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 SingleOperation<K,V>

getKey

public K getKey()

Description copied from interface: KeyBasedOperation

Retrieves the element key for this operation.

Specified by:

getKey in interface KeyBasedOperation<K>

Returns:

the key of the element that is concerned by the operation.

getValue

public V getValue()

getCreationTime

public long getCreationTime()

Description copied from interface: KeyBasedOperation

Retrieves the moment when the operation was created.

Specified by:

getCreationTime in interface KeyBasedOperation<K>

Returns:

the creation time in milliseconds

getType

public SingleOperationType getType()

Description copied from interface: SingleOperation

Returns a stable identifier for the type this operation can be classified in. This is used to group and order batched operations.

Specified by:

getType in interface SingleOperation<K,V>

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object other)

Overrides:

equals in class java.lang.Object
