Examples of IToolContext

org.locationtech.udig.project.ui.tool.IToolContext
A set of tools that is provided to Tool extensions.
In addition to the references available in the Toolkit class, ToolContext provides access to command factories and and to sendCommand methods.

Responsibilities:
- Provide access to the objects that an extension can use for its operations.
- Provide convenience methods for extension developers to use.
- Provide a consistent interface for extensions which will not easily change in future versions
