Description copied from interface: Attribution
Add the local lookup contributions to a view of an Environment.

The EnvironmentView contains the lookup matching criteria such as a specific name and accumulates candidate results.

The input ScopeView identifies the CS node and the containment of the CS child from which the lookup is made allowing derived implementations to present the alternative environments specified as the Inherited Attributes in the OCL Specification.

The returned ScopeView identifies an outer scope in which the lookup may be continued if the local candidate results are not suitable.

Specified by:
computeLookup in interface Attribution
Overrides:
computeLookup in class AbstractRootCSAttribution
environmentView - the EnvironmentView to compute
scopeView - the access selectivity to be applied by the lookup
Returns:
an outer ScopeView in which to continue the lookup, or null if none
