All Implemented Interfaces:

Task

public class MetadataSearchTask
extends BeanTask

This is the task for metadata searching. This task assumes it works against a folder bean. It will add searchXML as a non-required task parameter. During restoring state stage, it will get the request parameter "searchXML" and use it to restore the search object in the folder bean. This is the only extra responsibility taken by this provider.

Since:

MicroStrategy Web 9.0.0

public MetadataSearchTask()

Method Detail

registerParameterMetadata

protected void registerParameterMetadata(TaskParameterMetadata parameterMetadata)

Description copied from class: WebComponentTask

Registers a specific Task parameter metadata. This method is called by WebComponentTask.registerTaskMetadata(TaskMetadata). It is helpful to override in a Task so that a specific TaskParameterMetadata may be saved for later use.

Overrides:

registerParameterMetadata in class WebComponentTask

Parameters:

parameterMetadata - The TaskParameterMetadata object being saved.

collectData

protected void collectData(BeanTaskRequestContext btrContext)
                    throws TaskException

Description copied from class: WebComponentTask

This method calls the 'collectData' method on the WebBean instance. This method is called by WebComponentTask.processRequest(TaskRequestContext, TaskOutput).

Overrides:

collectData in class WebComponentTask

Parameters:

btrContext - The BeanTaskRequestContext object.

Throws:

TaskException - If there is a failure while trying to collect data for the Web Bean.

handleEvent

protected void handleEvent(BeanTaskRequestContext bsrContext)
                    throws TaskException

Description copied from class: WebComponentTask

This method instructs the WebBean to handle the event. It is called from WebComponentTask.processRequest(TaskRequestContext, TaskOutput).

Overrides:

handleEvent in class WebComponentTask

Parameters:

bsrContext - The BeanTaskRequestContext that contains the WebBean instance.

Throws:

TaskException - If something fails in the process of handling the event.

TaskRequestMalformedException - If there was an exception raised while handling the event.

prepareBean

protected void prepareBean(BeanTaskRequestContext bsrContext)
                    throws TaskException

Description copied from class: WebComponentTask

This method prepares the WebBean for execution. It is called by the WebComponentTask.processRequest(TaskRequestContext, TaskOutput) method. It performs the following actions:

1. Creates a new WebBean instance and adds it to the context. (calls WebComponentTask.createWebBean(BeanTaskRequestContext))
2. Sets any bean properties. (calls WebComponentTask.setBeanProperties(BeanTaskRequestContext))
3. Restores any bean state. (calls WebComponentTask.restoreBeanState(BeanTaskRequestContext))

Overrides:

prepareBean in class WebComponentTask

Parameters:

bsrContext - The BeanTaskRequestContext to use.

Throws:

TaskException - If anything fails along the way.
