Method Detail

getPKPropertyIds

protected Set<String> getPKPropertyIds()

Description copied from class: AbstractResourceProvider

Get the set of property ids that uniquely identify the resources of this provider.

Specified by:

getPKPropertyIds in class AbstractResourceProvider

Returns:

the set of primary key properties

createResources

public RequestStatus createResources(Request request)
                              throws SystemException,
                                     UnsupportedPropertyException,
                                     ResourceAlreadyExistsException,
                                     NoSuchParentResourceException

Description copied from class: AbstractAuthorizedResourceProvider

Create the resources defined by the properties in the given request object.

This implementation attempts to authorize the authenticated user before performing the requested operation. If authorization fails, an AuthorizationException will be thrown.

This method may be overwritten by implementing classes to avoid performing authorization checks to create resources.

Specified by:

createResources in interface ResourceProvider

Overrides:

createResources in class AbstractAuthorizedResourceProvider

Parameters:

request - the request object which defines the set of properties for the resources to be created

Returns:

the request status

Throws:

SystemException - an internal system exception occurred

AuthorizationException - if the authenticated user is not authorized to perform this operation

UnsupportedPropertyException - the request contains unsupported property ids

ResourceAlreadyExistsException - attempted to create a resource which already exists

NoSuchParentResourceException - a parent resource of the resource to create doesn't exist

getResourcesAuthorized

public Set<Resource> getResourcesAuthorized(Request request,
                                            Predicate predicate)
                                     throws SystemException,
                                            UnsupportedPropertyException,
                                            NoSuchResourceException,
                                            NoSuchParentResourceException

Description copied from class: AbstractAuthorizedResourceProvider

Get a set of resources based on the given request and predicate information if the authenticated user is authorized to do so.

This method must be overwritten if AbstractAuthorizedResourceProvider.getResources(Request, Predicate) is not overwritten.

Overrides:

getResourcesAuthorized in class AbstractAuthorizedResourceProvider

Parameters:

request - the request object which defines the desired set of properties

predicate - the predicate object which can be used to filter which resources are returned

Returns:

a set of resources based on the given request and predicate information

Throws:

SystemException - an internal system exception occurred

AuthorizationException - if the authenticated user is not authorized to perform this operation

UnsupportedPropertyException - the request contains unsupported property ids

NoSuchResourceException - the requested resource instance doesn't exist

NoSuchParentResourceException - a parent resource of the requested resource doesn't exist

See Also:

AbstractAuthorizedResourceProvider.getResources(Request, Predicate)

updateResources

public RequestStatus updateResources(Request request,
                                     Predicate predicate)
                              throws SystemException,
                                     UnsupportedPropertyException,
                                     NoSuchResourceException,
                                     NoSuchParentResourceException

Description copied from class: AbstractAuthorizedResourceProvider

Update the resources selected by the given predicate with the properties from the given request object.

This implementation attempts to authorize the authenticated user before performing the requested operation. If authorization fails, an AuthorizationException will be thrown.

This method may be overwritten by implementing classes to avoid performing authorization checks to update resources.

Specified by:

updateResources in interface ResourceProvider

Overrides:

updateResources in class AbstractAuthorizedResourceProvider

Parameters:

request - the request object which defines the set of properties for the resources to be updated

predicate - the predicate object which can be used to filter which resources are updated

Returns:

the request status

Throws:

SystemException - an internal system exception occurred

AuthorizationException - if the authenticated user is not authorized to perform this operation

UnsupportedPropertyException - the request contains unsupported property ids

NoSuchResourceException - the resource instance to be updated doesn't exist

NoSuchParentResourceException - a parent resource of the resource doesn't exist

deleteResources

public RequestStatus deleteResources(Request request,
                                     Predicate predicate)
                              throws SystemException,
                                     UnsupportedPropertyException,

Description copied from class: AbstractAuthorizedResourceProvider

Delete the resources selected by the given predicate.

This implementation attempts to authorize the authenticated user before performing the requested operation. If authorization fails, an AuthorizationException will be thrown.

deleteResources in class AbstractAuthorizedResourceProvider

Parameters:

request - the request object which defines the set of properties for the resources to be updated

predicate - the predicate object which can be used to filter which resources are deleted

Returns:

the request status
