FingerprintStorage

public FingerprintStorage()

Method Detail

get

public static FingerprintStorage get()

Returns the configured FingerprintStorage engine chosen by the user for the system.

getFileFingerprintStorage

public static FingerprintStorage getFileFingerprintStorage()

Returns the file system based FileFingerprintStorage configured on the system.

save

public abstract void save(Fingerprint fp)
                   throws IOException

Saves the given Fingerprint in the storage. This acts as a blocking operation. For file system based default storage, throws IOException when it fails.

Throws:

IOException - Save error

load

@CheckForNull
public abstract Fingerprint load(String id)
                                        throws IOException

Returns the Fingerprint with the given unique ID. The unique ID for a fingerprint is defined by Fingerprint.getHashString().

Throws:

IOException - Load error

delete

public abstract void delete(String id)
                     throws IOException

Deletes the Fingerprint with the given unique ID. This acts as a blocking operation. For file system based default storage, throws IOException when it fails. The unique ID for a fingerprint is defined by Fingerprint.getHashString(). TODO: Needed for external storage fingerprint cleanup.

Throws:

IOException - Deletion error

isReady

public abstract boolean isReady()

Returns true if there's some data in the fingerprint database.

iterateAndCleanupFingerprints

public abstract void iterateAndCleanupFingerprints(TaskListener taskListener)

Iterates a set of fingerprints, and cleans them up. Cleaning up a fingerprint implies deleting the builds associated with the fingerprints, once they are no longer available on the system. If all the builds have been deleted, the fingerprint itself is deleted. This method is called periodically by FingerprintCleanupThread. For reference, see FileFingerprintStorage.iterateAndCleanupFingerprints(TaskListener) For cleaning up the fingerprint cleanFingerprint(Fingerprint, TaskListener) may be used.

2.246

cleanFingerprint

public boolean cleanFingerprint(@NonNull
                                Fingerprint fingerprint,
                                TaskListener taskListener)

This method performs the cleanup of the given fingerprint.

Since:

2.246

getFingerprint

protected Fingerprint getFingerprint(Fingerprint fp)
                              throws IOException

Throws:

IOException

getDescriptor

public FingerprintStorageDescriptor getDescriptor()

Description copied from class: AbstractDescribableImpl

By default looks for a nested class (conventionally named DescriptorImpl) implementing Descriptor and marked with Extension.

Gets the descriptor for this instance.

Descriptor is a singleton for every concrete Describable implementation, so if a.getClass() == b.getClass() then by default a.getDescriptor() == b.getDescriptor() as well. (In rare cases a single implementation class may be used for instances with distinct descriptors.)

Specified by:

getDescriptor in interface Describable<FingerprintStorage>

Overrides:

getDescriptor in class AbstractDescribableImpl<FingerprintStorage>
