From a3241bec1cf1ae5fd514923ba5f923abc5427762 Mon Sep 17 00:00:00 2001 From: ktimoney Date: Tue, 13 Apr 2021 14:40:06 +0100 Subject: Add a new key class which uses @GeneratedValue to base classes This will provide an alternative unique key. It will be used in place of PfTimestampKey in the PdpStatistics table. We make use of the @GeneratedValue annotation to provide this feature. Added DummyGeneratedIdEntity and unit tests Added PfFilterFactory class Added new filter classes Issue-ID: POLICY-3189 Change-Id: I097eab318d2cb958e1157e35825fd6d35d429a25 Signed-off-by: ktimoney --- .../java/org/onap/policy/models/dao/PfDao.java | 32 +++++ .../java/org/onap/policy/models/dao/PfFilter.java | 91 +++++++++++++ .../onap/policy/models/dao/PfFilterFactory.java | 77 +++++++++++ .../onap/policy/models/dao/impl/DefaultPfDao.java | 147 +++++++++------------ .../models/dao/impl/PfNonTimestampKeyFilter.java | 46 +++++++ .../dao/impl/PfReferenceTimestampKeyFilter.java | 46 +++++++ .../models/dao/impl/PfTimestampKeyFilter.java | 46 +++++++ 7 files changed, 404 insertions(+), 81 deletions(-) create mode 100644 models-dao/src/main/java/org/onap/policy/models/dao/PfFilter.java create mode 100644 models-dao/src/main/java/org/onap/policy/models/dao/PfFilterFactory.java create mode 100644 models-dao/src/main/java/org/onap/policy/models/dao/impl/PfNonTimestampKeyFilter.java create mode 100644 models-dao/src/main/java/org/onap/policy/models/dao/impl/PfReferenceTimestampKeyFilter.java create mode 100644 models-dao/src/main/java/org/onap/policy/models/dao/impl/PfTimestampKeyFilter.java (limited to 'models-dao/src/main/java') diff --git a/models-dao/src/main/java/org/onap/policy/models/dao/PfDao.java b/models-dao/src/main/java/org/onap/policy/models/dao/PfDao.java index eb77be9c0..844759367 100644 --- a/models-dao/src/main/java/org/onap/policy/models/dao/PfDao.java +++ b/models-dao/src/main/java/org/onap/policy/models/dao/PfDao.java @@ -27,6 +27,7 @@ import java.util.List;
