public class DefaultRequestController
extends AbstractRequestController

This is TaggerCat's default RequestController. Action mappings can be provided via one or more of the following:

• Servlet init parameters
• Basic Actions Annotations
• Query String Regular expression Annotations
• URI Regular expression Annotations
• EL Expression Annotations
• URI Pattern Annotations

The Request Controller delegates requests to appropriate request handlers. To implement your own subclass of an existing handler, register your subclass with the same action name.

The standard action names are:

closeDataSources

closes the named data sources

delete

delete the current tcEntity from the data source

deleteSelected

deletes the selected rows in the data source

goFirst, goNext, goPrevious, goLast

scrolls the specified data source to the named position

insert

performs an insert action with data from the current request

login

logs in the user

logout

logs off the current user

noop

no operation, allows for page reload with no action

pageNavigate

performs a page navigate

qbf

performs a QBF style query on the data source

qbfClear

clears any QBF data on the current data source

query

performs a query ( or re-query ) action on the specified data source

reloadMetadata

reloads the System metadata, including derivations, and constraints etc.

reload

reloads the current entity on the named data source

save

performs a save action on the specified data source

saveall

performs a save action on all data sources within a single transaction

sort

performs a sort on the specified property name

undo

performs an undo action on the specified datasource

undoAll

performs an undo action on all data sources

update
