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

getResources

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

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

Note that it is not required for this resource provider to completely filter the set of resources based on the given predicate. It may not be possible since some of the properties involved may be provided by another provider. This partial filtering is allowed because the predicate will always be applied by the calling cluster controller. The predicate is made available at this level so that some pre-filtering can be done as an optimization.

A simple implementation of a resource provider may choose to just return all of the resources of a given type and allow the calling cluster controller to filter based on the predicate.

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 get resources.

Specified by:

getResources in interface ResourceProvider

Overrides:

getResources 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

updateResources

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

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,
                                     NoSuchResourceException,
                                     NoSuchParentResourceException

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.

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

Specified by:

deleteResources in interface ResourceProvider

Overrides:

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

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 deleted doesn't exist

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