public final class ManagedScopeDeriver
extends ConflictResolver.ScopeDeriver

A scope deriver for use with ConflictResolver that supports the scopes from ScopeManager. It basically chooses "narrowest" scope, based on parent and child scopes.

Method Details

deriveScope

public void deriveScope(ConflictResolver.ScopeContext context)

Description copied from class: ConflictResolver.ScopeDeriver

Determines the scope of a dependency in relation to the scope of its parent. Implementors need to call ConflictResolver.ScopeContext.setDerivedScope(String) to deliver the result of their calculation. If said method is not invoked, the conflict resolver will assume the scope of the child dependency remains unchanged.

Specified by:

deriveScope in class ConflictResolver.ScopeDeriver

Parameters:

context - The scope context, must not be null.

getDerivedScope

public String getDerivedScope(String parentScope,
 String childScope)

Visible for testing. It chooses "narrowest" scope out of parent or child, unless child is system scope.
