Parameters:

filename - The filename for this entry

md5sum - The checksum for this entry

Method Detail

getGeneralStoreState

public ArchiveStoreState getGeneralStoreState()

Get the ArchiveStoreState for the entry in general. This is computed from the ArchiveStoreStates for the bitarchives.
1. If no information about the bitarchives are available, the state UPLOAD_FAILED with timestamp=NOW is returned
2. If there are information about one bitarchive, the state of this bitarchive is returned.
3. If there are information from more than one bitarchive, A. if the state of one of the bitarchives equals UPLOAD_FAILED, the state UPLOAD_FAILED with the latest timestamp is returned B. else, find the lowest state of the N bitarchives: return this state together with the the latest timestamp

Note that the storestate and the timestamp might not come from the same bitarchive.

Returns:

the current ArchiveStoreState for the entry in general

getStoreState

public ReplicaStoreState getStoreState(String baId)

Get the StoreState for this entry for a given bitarchive or null if none.

Parameters:

baId - a bitarchive id

Returns:

the StoreState for a given bitarchive.

getChecksum

public String getChecksum()

Get the checksum for this entry.

Returns:

the stored checksum for this entry
