All Implemented Interfaces:

IOperationDelegate, IOperationCacheHandler

public class ServerFirstCacheHandler
extends AbstractRestCacheHandler

This is a common implementation for the IOperationCacheHandler that executes the operation and stores a successful result in the cache. If the operation failed (e.g. if the backend is not available), the handler tries to load the requested resource in the cache.

Method Detail

beforeOperationExecution

public void beforeOperationExecution(IOperation operation)

Description copied from interface: IOperationCacheHandler

Is invoked before the operation itself is started with IOperation#internalExecute(). Can be used to read some data from the cache and set it into the operation.

Specified by:

beforeOperationExecution in interface IOperationCacheHandler

Overrides:

beforeOperationExecution in class NoCacheHandler

afterOperationExecution

public void afterOperationExecution(IOperation operation)

Description copied from interface: IOperationCacheHandler

Is invoked after the operation itself is started with IOperation#internalExecute(). Can be used to read data from the operation and write it into the cache.

Specified by:

afterOperationExecution in interface IOperationCacheHandler

Overrides:

afterOperationExecution in class AbstractRestCacheHandler

skipOperationExecution

public boolean skipOperationExecution(IOperation operation)

Specified by:

skipOperationExecution in interface IOperationCacheHandler

Overrides:

skipOperationExecution in class NoCacheHandler

Returns:

true if the execution of the IOperation should be skipped, e.g. if the result is offline and the operation will fail anyway (with a costly timeout).

onOperationFailed

public void onOperationFailed(IOperation operation)

Description copied from interface: IOperationDelegate

Notifies this listener that the watched IOperation failed. This only indicates an exception during the execution and is independent from the operation's result code.

Specified by:

onOperationFailed in interface IOperationDelegate

Overrides:

onOperationFailed in class AbstractOperationDelegate

Parameters:

operation - The watched IOperation.

onOperationSuccessful

public void onOperationSuccessful(IOperation operation)

Description copied from class: AbstractOperationDelegate

Is called when the operation executed successfully (i.e. the response code is correct)

Overrides:

onOperationSuccessful in class NoCacheHandler

Parameters:

operation - the successful IOperation (incl. the result string)
