Constructor Detail

GridFSBlobGarbageCollector

public GridFSBlobGarbageCollector()

Method Detail

computeToDelete

public void computeToDelete()

Description copied from class: AbstractBlobGarbageCollector

Computes keys candidate for deletion.

Overrides should not call super (this allows detecting old implementations).

Overrides:

computeToDelete in class AbstractBlobGarbageCollector

getId

public String getId()

Description copied from interface: BinaryGarbageCollector

Gets a unique identifier for this garbage collector. Two garbage collectors that would impact the same files must have the same identifier.

Returns:

a unique identifier

mark

public void mark(String key)

Description copied from interface: BinaryGarbageCollector

Marks a binary as being in use.

Specified by:

mark in interface BinaryGarbageCollector

Overrides:

mark in class AbstractBlobGarbageCollector

Parameters:

key - the binary's digest

removeUnmarkedBlobsAndUpdateStatus

public void removeUnmarkedBlobsAndUpdateStatus(boolean delete)

Overrides:

removeUnmarkedBlobsAndUpdateStatus in class AbstractBlobGarbageCollector
