From 55d1e6f63df516019032ebf0c1e9c8c0495a619d Mon Sep 17 00:00:00 2001 From: Tuukka Lehtonen Date: Thu, 17 Oct 2019 10:52:39 +0300 Subject: [PATCH] Rid TypicalPropertyTester of database read transactions After this, the normal workbench invocations of TypicalPropertyTester no longer perform any database transactions to do their work. DiagramViewer now has built-in support for doing the required queries based on IDiagram hints alone. gitlab #399 Change-Id: I0dcebcc871f72c16d58a932704c16398df9dd900 --- .../db/common/request/ResourceSetURIs.java | 48 +++++++ .../simantics/db/common/request/TypeURIs.java | 36 +++++ .../diagram/ui/DiagramModelHints.java | 28 +++- .../ui/diagramEditor/DiagramViewer.java | 53 ++++++-- .../HasDiagramSourceListener.java | 58 ++++++++ ...yncCurrentTypicalInstanceWithTemplate.java | 3 +- ...SyncCurrentTypicalTemplateToInstances.java | 3 +- .../ui/property/TypicalPropertyTester.java | 127 ++++++++++-------- 8 files changed, 287 insertions(+), 69 deletions(-) create mode 100644 bundles/org.simantics.db.common/src/org/simantics/db/common/request/ResourceSetURIs.java create mode 100644 bundles/org.simantics.db.common/src/org/simantics/db/common/request/TypeURIs.java create mode 100644 bundles/org.simantics.modeling.ui/src/org/simantics/modeling/ui/diagramEditor/HasDiagramSourceListener.java diff --git a/bundles/org.simantics.db.common/src/org/simantics/db/common/request/ResourceSetURIs.java b/bundles/org.simantics.db.common/src/org/simantics/db/common/request/ResourceSetURIs.java new file mode 100644 index 000000000..0cc29e116 --- /dev/null +++ b/bundles/org.simantics.db.common/src/org/simantics/db/common/request/ResourceSetURIs.java @@ -0,0 +1,48 @@ +/******************************************************************************* + * Copyright (c) 2019 Association for Decentralized Information Management + * in Industry THTH ry. + * All rights reserved.
