id - bnode ID.

Method Detail

getCreator

public Object getCreator()

Description copied from interface: MemValue

Returns the object that created this MemValue. MemValues are only unique within a single repository, but an application could use several repositories at the same time, passing MemValues generated by one Sail to another Sail. In such situations, the MemValue of the first Sail cannot be used by the second Sail.

Specified by:
