A dynamic variable is a variable whose value is computed dynamically by a resolver at the time a string substitution is performed. A dynamic variable is contributed by an extension.
The following is a definition of a dynamic variable that resolves to the name of the selected resource:
<extension point="org.eclipse.core.variables.dynamicVariables"> <variable name="resource_name" resolver="com.example.ResourceNameResolver" description="The name of the selected resource" supportsArgument="false"> </variable> </extension>
Clients are not intended to implement this interface. Instead, clients contributing
a dynamic variable provide an implementation of IDynamicVariableResolver
.
