IMatterService
Represents the matter API service.
Creates the specified [Matter](https://relativitydev.github.io/relativity.testing.framework/api/Relativity.Testing.Framework.Models.Matter.html).
Deletes the [Matter](https://relativitydev.github.io/relativity.testing.framework/api/Relativity.Testing.Framework.Models.Matter.html) by ArtifactID.
Gets the [Matter](https://relativitydev.github.io/relativity.testing.framework/api/Relativity.Testing.Framework.Models.Matter.html) by the ArtifactID.
Gets the [Matter](https://relativitydev.github.io/relativity.testing.framework/api/Relativity.Testing.Framework.Models.Matter.html) by the matter name, and Client ArtifactID.
Gets all of available clients in a Relativity environment.
Gets all of available matter statuses in a Relativity environment.
Requires the specified matter.
If the [ArtifactID](https://relativitydev.github.io/relativity.testing.framework/api/Relativity.Testing.Framework.Models.Artifact.html#Relativity_Testing_Framework_Models_Artifact_ArtifactID) property of entity has a positive value, this gets the matter by ID and updates it.Else if the [Name](https://relativitydev.github.io/relativity.testing.framework/api/Relativity.Testing.Framework.Models.NamedArtifact.html#Relativity_Testing_Framework_Models_NamedArtifact_Name) property of entity have a value, this gets the matter by name and client ID and updates it, if it exists.Otherwise this creates a new matter using ICreateWorkspaceEntityStrategy<T>.
Updates the specified [Matter](https://relativitydev.github.io/relativity.testing.framework/api/Relativity.Testing.Framework.Models.Matter.html).
