Examples of org.apache.ode.bpel.common.CorrelationKeySet

org.apache.ode.bpel.common.CorrelationKeySet
This class implements a set of correlation keys. The example of canonical forms of correlation key sets are:
- @2
- @2[12~a~b]
- @2[12~a~b],[25~b~c]
The first example shows an empty correlation key set. The second shows a set with one correlation key inside. The third shows a set with two keys inside. The correlation keys are sorted by the correlation set ids. @author sean
