Method Detail

changeSetExists

public boolean changeSetExists(int resourceId,
                               Headers headers)

Specified by:

changeSetExists in interface ChangeSetManager

findChangeSet

public File findChangeSet(int resourceId,
                          String driftDefinitionName)
                   throws IOException

Description copied from interface: ChangeSetManager

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

Specified by:

findChangeSet in interface ChangeSetManager

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

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

Specified by:

findChangeSet in interface ChangeSetManager

getChangeSetReader

public ChangeSetReader getChangeSetReader(int resourceId,
                                          String driftDefinitionName)
                                   throws IOException

Description copied from interface: ChangeSetManager

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.

Specified by:

getChangeSetReader in interface ChangeSetManager

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
