Examples of com.atomikos.icatch.CompositeTransaction

com.atomikos.icatch.CompositeTransaction
Represents a nested part of a global composite transaction. Each invocation of a server is represented by an instance of this type. For transaction proxies (instances that represent non-local transactions), all non-trivial methods are allowed to generate an exception of type UnsupportedOperationException. The only methods that always work for all instances are the simple getters and test methods.
