The omit parameter filters out the defined methods, but leaves the sub-calls, which are included in the resulting sequence diagram. In contrast, the boundary parameter 'upto=<regex>' excludes the given method and all its consecutive callees.
Given the class net.sf.jsequnit.example.SequenceSample containing a method boundaryMethod that consecutively calls the methods.
where the JavaDoc of the method contains a sequence diagram tag with the following boundary parameter:
@sequence.diagram test=net.sf.jsequnit.example.SequenceSampleTest#testBoundaryMethod() upto=net.sf.jsequnit.example.SequenceSample.callingMethod
we get a sequence diagram containing the call to the method callingMethod, but no references to the method calls of the method body (i.e. calledMethod).
