If we dip down to zero subscribers, no future updates are streamed. This hasn't been seen historically, because the cash metrics observer is always present, but this will be moved out of node.
* Provide sorting by state reference (and individual constituents of: txId, index)
* Fixed formatting.
* Updated import following rebase from master.
* Updated import following rebase from master.
Name Exceptions <blah>Exception
Swap null / non null annotations onto the correct classes
Don't shadow parameters with local vars
Explicitly handle Character Type
* Partial (ie. incomplete) implementation of Aggregate Functions.
* Completed implementation of Aggregate Functions (sum, count, max, min, avg) with optional grouping.
* Completed Java DSL and associated JUnit tests.
* Added optional sorting by aggregate function.
* Added Jvm filename annotation on QueryCriteriaUtils.
* Added documentation (API and RST with code samples).
* Incorporating feedback from MH - improved readability in structuring Java and/or queries.
* Remove redundant import.
* Removed redundant commas.
* Streamlined expression parsing (in doing so, remove the ugly try-catch raised by RP in PR review comments.)
* Added JvmStatic and JvmOverloads to Java DSL; removed duplicate Kotlin DSL functions using default params; changed varargs to lists due to ambiguity
* Fix missing imports after rebase from master.
* Fix errors following rebase from master.
* Updates on expression handling following feedback from RP.
* Identities returned from TxKeyFlow were backwards, meaning keys were incorrectly assigned to the remote and local identities. Added unit test covering this case and corrected the flow logic.
* Rename TxKeyFlow to TransactionKeyFlow
* Correct registration of transaction key flows
* Move TransactionKeyFlow.Provider into CoreFlowHandlers
* Move TransactionKeyFlow.Request up to the top level class instead of being a class within an object.
* Remove AbstractIdentityFlow and move the validation logic into individual flows to make it clearer that it's registering the received identities.
* Cash flows now return the recipient identity instead of full identity lookup, as this is what
the caller actually needs and simplifies a lot of cases.
Remove prohibition against non string object classes such as arrays
Squashed Commmits:
* Tidyup whitespace
* WIP
* Review Comments
* WIP - adding concept of nullabltily into the carpenter
* Add explicit nullable and non nullable fields
* Rebase onto master, fix package names in carpenter
* Fix https://github.com/corda/corda/issues/949 by providing a default StateStatus argument to all QueryCriteria types.
* Abstracted Common Criteria into its own abstract data class + associated visitor.
* Incorporating feedback from RP PR review.
