Modifying the default usage

Usage indicates how a component is intended to be included in the project when this version is released.

Possible usage values are:

• Statically Linked. A tightly-integrated component that is statically linked in and distributed with your project.

• Dynamically Linked. A moderately-integrated component that is dynamically linked in, such as with DLLs or .jar files.

• Source Code. Source code such as .java or .cpp files.

• Dev Tool / Excluded. Component will not be included in the released project. For example, a component that is used internally for building, development, or testing. Examples are unit tests, IDE files, or a compiler.

• Separate Work. Intended for loosely-integrated components. Your work is not derived from the component. To be considered a separate work, your application has its own executables, with no linking between the component and your application. An example is including the free Acrobat PDF Viewer with your distribution media.

• Implementation of Standard. Intended for cases where you implemented according to a standard. For example, a Java spec request that ships with your project.

• Merely Aggregated. Intended for components that your project does not use or depend upon in any way, although they may be on the same media. For example, a sample version of an unrelated product included with your distribution.

• Prerequisite. Intended for components that are required but not provided by your distribution.

• Unspecified. The usage for this component has not yet been determined.

In Black Duck version 2020.10.0, Black Duck introduced the UNSPECIFIED usage value, which you can use as a default option instead of existing defaults to eliminate confusion over whether the component is assigned a true usage value or a default usage value. For example, if you use DYNAMICALLY_LINKED as the default usage value, you might not be able to distinguish between components that have a true usage value of DYNAMICALLY_LINKED and those components that are assigned the usage value by default. By using UNSPECIFIED as the usage default, you know that you should take action to assign a valid usage value when you see UNSPECIFIED assigned as the usage value.

The default usage is determined by match type: Snippets have a usage of Source Code while all other match types are Dynamically Linked.

Black Duck uses the following variables so that you can change the default usage for similar match types:

• BLACKDUCK_HUB_FILE_USAGE_DEFAULT. Defining a usage for this variable sets the default value for the following match types:

  • Binary

  • Exact Directory

  • Exact File

  • Files Added/Deleted

  • Files Modified

  • Partial

• BLACKDUCK_HUB_DEPENDENCY_USAGE_DEFAULT. Defining a usage for this variable sets the default value for the following match types:

  • File Dependency

  • Direct Dependency

  • Transitive Dependency

• BLACKDUCK_HUB_SOURCE_USAGE_DEFAULT. Defining a usage for this variable sets the default value for the following match types:

  • Snippet

• BLACKDUCK_HUB_MANUAL_USAGE_DEFAULT. Defining a usage for this variable sets the default value for the following match types:

  • Manually Added

  • Manually Identified

• BLACKDUCK_HUB_SHOW_UNMATCHED: Determines whether the unmatched component count is shown. The default is false (not shown).
