* Added constraint type information to vault states table. * Added Vault Query criteria support for constraint data. * Added documentation and changelog entry. * Added missing @CordaSerializable. * Fix minor bug in test setup and parsing code. * Use binary encoding data types instead of serialize/deserialize. * Optimized storage of constraints data. Additional assertions on Vault Query constraint data contents (to validate encoding/decoding). Tested with CompositeKey containing 10 keys. * Addressing PR review feedback. * Query by constraints type and data. * Revert back accidentally removed code for contractStateType filtering. * Incorporating final PR review feedback. Use @JvmOverloads on constructor. * Make sure constraintInfo is class evolution friendly. |
