segment

public void segment()

Description copied from interface: RDFChanges

Segment marker.

A segment is a number of transactions; the grouping rationale is not defined by RDF Patch.

It might be used to indicate a logical collection of change transactions in a long stream of transactions.

There is no guarantee it will be used.

Segments must contain complete transactions.
Segments must not span start-finish pairs.

Specified by:

segment in interface RDFChanges

Overrides:

segment in class RDFChangesWriterText
