COMSOL 6.2 - Creating and Updating Database Objects

Creating and Updating Database Objects

You can create new, or update existing, database objects via methods in the Model Manager API. Such methods typically come in pairs: one simple variant that takes a few mandatory arguments and that relies heavily on defaults for most settings, and one advanced variant that enables you to fully specify all settings — see Advanced Database Operations Using Parameter Objects for further details.

Examples

Create a new repository in the database with name My Repository. The second argument is the comment for the first commit automatically saved to the new repository’s default branch.

Repository repository = database
.createRepository("My Repository", "Created a new repository.");

The comment can always be skipped when saving a commit — in the previous example done by passing null for the second argument.

Create a new branch with name My Branch from the default branch. The third argument is the comment for the first commit automatically saved to the new branch.

BranchKey branchKey = repository.defaultBranch().branchKey();

Branch branch = repository
.createBranch("My Branch", branchKey, "Created a new branch.");

Create a tag in the new branch with title My Tag. Assign the new tag to a model on the branch.

TagItemVersion version = branch
.saveNewTag("My Tag", "Created a new tag.");

// The modelItemKey variable identifying the model item is
// assumed to be initialized elsewhere.

branch
.modelByKey(modelItemKey)
.assignTag(version.itemKey(), "Assigned a tag to the model.");

Update the title of the tag.

BranchTagItem branchTagItem = version.branchItem();

TagItemVersion secondVersion = branchTagItem
.updateTitle("My Renamed Tag", "Renamed the newly created tag.");


	Tags are version controlled in exactly the same way as models and files. Updating the tag is done on a specific branch and results in a new version of the tag.
