Method Detail

changeSetExists

boolean changeSetExists(int resourceId,
                        Headers headers)

findChangeSet

File findChangeSet(int resourceId,
                   String driftDefinitionName)
                   throws IOException

Locates the latest coverage change set for the specified resource id and drift definition.

Parameters:

resourceId - The id of the resource to which the change set belongs

driftDefinitionName - The name of the drift definition for which the change set was generated

Returns:

The change set file or null if it is not found

Throws:

IOException

findChangeSet

File findChangeSet(int resourceId,
                   String name,
                   org.rhq.core.domain.drift.DriftChangeSetCategory type)

getChangeSetReader

ChangeSetReader getChangeSetReader(int resourceId,
                                   String driftDefinitionName)
                                   throws IOException

Locates the latest change set for the given resource and drift definition and returns a ChangeSetReader for that change set. Note that a resource can have multiple drift definitions; so, both the resource id and the drift definition are required to uniquely identify a particular change set.

Parameters:

resourceId - The id of the resource to which the change set belongs

driftDefinitionName - The name of the drift definition for which the change set was generated

Returns:

A ChangeSetReader that is open on the change set identified by resourceId and driftDefinition. Returns null if no change set has previously been generated.

Throws:

IOException
