Class AssetOffloadingProcess

java.lang.Object

com.day.cq.dam.core.process.AssetOffloadingProcess

All Implemented Interfaces:

WorkflowExternalProcess

@Service
public class AssetOffloadingProcess
extends java.lang.Object
implements WorkflowExternalProcess

This component implements an workflow external step, that allows offloading asset based workflows, means workflows that have an asset on the payload.

The workflow (model) to offload must be set on the step metadata using the workflowModel argument.

Method Detail

execute

public java.io.Serializable execute(WorkItem item,
                                    WorkflowSession wfSession,
                                    MetaDataMap arguments)
                             throws WorkflowException

Description copied from interface: WorkflowExternalProcess

Executes the external process step. In order to keep track of this asynchronous process, an identifier must be returned. One can return null to indicate that nothing was executed. In this case, the step directly advances to the next step.

Specified by:

execute in interface WorkflowExternalProcess

Parameters:

item - The current work item

wfSession - The current workflow session

arguments - The current steps node arguments (aka as node meta data)

Returns:

Any serializable identifier for the external process executed, or null

Throws:

WorkflowException - thrown in case something goes wrong during execution

hasFinished

public boolean hasFinished(java.io.Serializable externalProcessId,
                           WorkItem item,
                           WorkflowSession session,
                           MetaDataMap arguments)

Description copied from interface: WorkflowExternalProcess

Tests the external process, given by the external process id, for completeness.

Specified by:

hasFinished in interface WorkflowExternalProcess

Parameters:

externalProcessId - The external process to test for completeness

item - The current work item

session - The current workflow session

arguments - The current steps node arguments (aka as node meta data)

Returns:

true if the specified external process has finished

handleResult

public void handleResult(java.io.Serializable externalProcessId,
                         WorkItem workItem,
                         WorkflowSession session,
                         MetaDataMap arguments)
                  throws WorkflowException

Description copied from interface: WorkflowExternalProcess

Get and handle the result of the external process, given by the external process id. This would include storing any results where appropriate for further use.

Specified by:

handleResult in interface WorkflowExternalProcess

Parameters:

externalProcessId - The external process to handle the results for

workItem - The current work item

session - The current workflow session

arguments - The current steps node arguments (aka as node meta data)

Throws:

WorkflowException - thrown in case something goes wrong during execution
