Method Detail

write

public final void write(Binary data)
                 throws PersistenceExceptionTransfer

Specified by:

write in interface PersistenceTarget<Binary>

Throws:

PersistenceExceptionTransfer

read

public final XGettingCollection<? extends Binary> read()
                                                throws PersistenceExceptionTransfer

Description copied from interface: PersistenceSource

A general, unspecific read, e.g. to initially read data in general from the attached data source.

Examples:

• simply ALL data from a plain file.
• only root nodes (and all recursively referenced nodes) of a graph-based database.
• nothing at all if not applicable, resulting in null being returned.

Specified by:

read in interface PersistenceSource<Binary>

Returns:

data segments containing general data if applicable, otherwise null.

Throws:

PersistenceExceptionTransfer

readByObjectIds

public final XGettingCollection<? extends Binary> readByObjectIds(PersistenceIdSet[] oids)
                                                           throws PersistenceExceptionTransfer

Specified by:

readByObjectIds in interface PersistenceSource<Binary>

Throws:

PersistenceExceptionTransfer
