Equality of event classes is based on their classifier, i.e., if two
event classes have the same classifier, they are considered as equal in
terms of this method.
Retrieves the set of attribute keys which are used
in this event classifier (May be used for the construction
of events that are not part of an existing event class).
Lazy implementation of the random access storage in NikeFS2:
Blocks are copied as late as possible (soft copies), while
retaining soft links otherwise.
This factory will create buffered implementations of
all model hierarchy elements wherever possible, i.e.,
the latest optimizations available in OpenXES will be
employed.
This class implements an input stream which can provide
a progress listener with feedback about how much of the
data in the stream has already been read.
