## Remarks

This class helps improve performance when calling the [ContentBuildInterface.CalculateBuildUsageTags](/engine/6000.5/script-reference/unityeditor/build/content/contentbuildinterface/calculatebuildusagetags.md) api multiple times.

Note: this class and its members exist to provide low-level support for the **Scriptable Build Pipeline** package. This is intended for internal use only; use the [Scriptable Build Pipeline package](https://docs.unity3d.com/Packages/com.unity.scriptablebuildpipeline@latest/index.html) to implement a fully featured build pipeline. You can install this via the [Package Manager window](/engine/6000.5/manual/packages-list/upm-ui-window/upm-ui.md).
