Method Detail

getLiveResourceAvailability

org.rhq.core.domain.measurement.ResourceAvailability getLiveResourceAvailability(org.rhq.core.domain.auth.Subject subject,
                                                                                 int resourceId)

Returns the availability of the resource with the specified id. This performs a live check - a resource will be considered UNKNOWN if the agent cannot be contacted for any reason.

Parameters:

subject - The logged in user's subject.

resourceId - the id of a Resource in inventory.

Returns:

the resource availability - note that if the encapsulated availability type is null, the resource availability is UNKNOWN.

Throws:

FetchException - if the resource represented by the resourceId parameter does not exist, or if the passed subject does not have permission to view this resource.

getResource

org.rhq.core.domain.resource.Resource getResource(org.rhq.core.domain.auth.Subject subject,
                                                  int resourceId)

Returns the Resource with the specified id.

Parameters:

subject - The logged in user's subject.

resourceId - the id of a Resource in inventory.

Returns:

the resource

Throws:

FetchException - if the resource represented by the resourceId parameter does not exist, or if the passed subject does not have permission to view this resource.

findResourceLineage

List<org.rhq.core.domain.resource.Resource> findResourceLineage(org.rhq.core.domain.auth.Subject subject,
                                                                int resourceId)

Returns the lineage of the Resource with the specified id. The lineage is represented as a List of Resources, with the first item being the root of the Resource's ancestry (or the Resource itself if it is a root Resource (i.e. a platform)) and the last item being the Resource itself. Since the lineage includes the Resource itself, the returned List will always contain at least one item.

Parameters:

subject - The logged in user's subject.

resourceId - the id of a Resource in inventory

Returns:

the lineage of the Resource with the specified id

Throws:

FetchException - on any issue. Wraps ResourceNotFoundException when necessary.

updateResource

org.rhq.core.domain.resource.Resource updateResource(org.rhq.core.domain.auth.Subject subject,
                                                     org.rhq.core.domain.resource.Resource resource)

Update resource's editable properties (name, description, location).

Parameters:

user - the logged in user

resource - the resource to update

Returns:

the updated resource

uninventoryResources

List<Integer> uninventoryResources(org.rhq.core.domain.auth.Subject subject,
                                   int[] resourceIds)

Removes these resources from inventory. The resources may subsequently be rediscovered. Note that for each specified resource all children will also be removed, it it not necessary or recommended to specify more than one resource in the same ancestry line.

Parameters:

subject - The logged in user's subject.

resourceIds - The resources to uninventory.

findResourcesByCriteria

org.rhq.core.domain.util.PageList<org.rhq.core.domain.resource.Resource> findResourcesByCriteria(org.rhq.core.domain.auth.Subject subject,
                                                                                                 org.rhq.core.domain.criteria.ResourceCriteria criteria)

findChildResources

org.rhq.core.domain.util.PageList<org.rhq.core.domain.resource.Resource> findChildResources(org.rhq.core.domain.auth.Subject subject,
                                                                                            int resourceId,
                                                                                            org.rhq.core.domain.util.PageControl pageControl)

getParentResource

org.rhq.core.domain.resource.Resource getParentResource(org.rhq.core.domain.auth.Subject subject,
                                                        int resourceId)

getResourcesAncestry

Map<Integer,String> getResourcesAncestry(org.rhq.core.domain.auth.Subject subject,
                                         Integer[] resourceIds,
                                         org.rhq.core.domain.resource.ResourceAncestryFormat format)

Resource.ancestry is an encoded value that holds the resource's parental ancestry. It is not suitable for display. This method can be used to get decoded and formatted ancestry values for a set of resources. A typical usage would a criteria resource fetch, and then a subsequent call to this method for ancestry display, potentially for resource disambiguation purposes.

Parameters:

subject -

resourceIds -

format -

Returns:

A Map of ResourceIds to FormattedAncestryStrings, one entry for each unique, valid, resourceId passed in.
