index class %IPM.General.SemanticVersion.Index extends %Library.FunctionalIndex

Functional index on semantic versions. This serves two purposes:

1. Enable searching based on module name and semantic version expression without scanning the whole extent
2. Simplify ordering based on latest semantic version, properly handling major/minor/patch version numbers and prerelease designations.

To use this index in a class, define an index on a string property (the module name) and a property of type %IPM.General.SemanticVersion. Index SemVer On (Name, Version) As %IPM.General.SemanticVersion.Index; You must also define a property with the same name as that index, as follows: Property SemVer As %String(MAXLEN = 512) [ SqlComputeCode = {set {*} = ##class(%IPM.Repo.Filesystem.Cache).SemVerNode({Name},{Version})}, SqlComputed, SqlComputeOnChange = (%%INSERT, %%UPDATE) ];

For an example, see %IPM.Repo.Filesystem.Cache.

To use the generated Find method and the %IPM.General.SemanticVersion.Find (as in the example of %IPM_PackageManager_Server._Module): SELECT Name,VersionString FROM %IPM_PackageManager_Server._Module WHERE ID %INSET %IPM_PackageManager_Server.Module_SemVerFind('HS.JSON','0.x','snapshot') To facilitate ordering by semantic version, classes that define such indices may also implement class queries to wrap %IPM.General.SemanticVersion.Find:Matches.
