generateUnifiedDiff

org.rhq.core.domain.drift.FileDiffReport generateUnifiedDiff(org.rhq.core.domain.auth.Subject subject,
                                                             org.rhq.core.domain.drift.Drift<?,?> drift)

Generates a unified diff of the two files references by drift. In the case of a modified file, a Drift object references the current and previous versions of the file. This method generates a diff of the two versions.

Parameters:

drift - Specifies the two files that will be compared

Returns:

A report containing a unified diff of the two versions of the file referenced by drift

generateUnifiedDiff

org.rhq.core.domain.drift.FileDiffReport generateUnifiedDiff(org.rhq.core.domain.auth.Subject subject,
                                                             org.rhq.core.domain.drift.Drift<?,?> drift1,
                                                             org.rhq.core.domain.drift.Drift<?,?> drift2)

Generates a unified diff of the two files referenced by drift1 and drift2. More specifically, the files referenced by Drift.getNewDriftFile() are compared.

Parameters:

drift1 - References the first file to be compared

drift2 - References the second file to be compared

Returns:

A report containing a unified diff of the two files compared

generateUnifiedDiffByIds

org.rhq.core.domain.drift.FileDiffReport generateUnifiedDiffByIds(org.rhq.core.domain.auth.Subject subject,
                                                                  String driftId1,

Generates a unified diff of the two file versions referenced by drift ids.

Parameters:

drift1Id - the "new" version of the first drift

drift2Id - the "new" version of the second drift

Returns:

A report containing a unified diff of the two versions of the file referenced by drift

getDriftFileBits

String getDriftFileBits(org.rhq.core.domain.auth.Subject subject,
                        String hash)

Returns the content associated with the specified hash as a string

Parameters:

hash - The hash the uniquely identifies the requested content

Returns:

The content as a string

getDriftFileAsByteArray

byte[] getDriftFileAsByteArray(org.rhq.core.domain.auth.Subject subject,
                               String hash)

getSnapshot

org.rhq.core.domain.drift.DriftSnapshot getSnapshot(org.rhq.core.domain.auth.Subject subject,
                                                    org.rhq.core.domain.drift.DriftSnapshotRequest request)

Calculate and return requested Drift Snapshot.

Parameters:

subject -

request -

Returns:

The DriftSnapshot Not null but version is set to -1 if the drift definition does not yet have any snapshots or there are no snapshots that meet the requested snapshot version constraints.

Throws:

IllegalArgumentException - if the specified drift definition does not exist

pinSnapshot

void pinSnapshot(org.rhq.core.domain.auth.Subject subject,
                 int driftDefId,
                 int snapshotVersion)

updateDriftDefinition

void updateDriftDefinition(org.rhq.core.domain.auth.Subject subject,
                           org.rhq.core.domain.common.EntityContext entityContext,
                           org.rhq.core.domain.drift.DriftDefinition driftDef)

Saves or updates the provided drift definition. If the definition, identified by name, already exists, an update is performed; otherwise, a new drift definition is saved. Agents if available will be notified of the change. If agents are unreachable, the definition will still be saved/updated. Changes will then propagate to agents the next time they do an inventory sync.

Several validation checks are performed before the definition is persisted. If it is a new definition, the following checks are performed:

• Verify that the resource supports drift management
• Verify that the template (if specified) already exists in the database
• Verify that the template (if specified) belongs to the correct resource type

For new and existing definitions these additional checks are performed:

• Verify that the definition name does not contain illegal characters
• Verify that the base directory does not contain illegal characters
• Verify that filters do not contain illegal characters

Parameters:

subject -

entityContext -

driftDef -
