Constructor
 
     public NameBasedResolver(BeanManagerImpl managerIterable<? extends Bean<?>> allBeans) {
         this. = CacheBuilder.newBuilder().build(new NameToBeanSet(managerallBeans));
     }

    
Reset all cached injection points. You must reset all cached injection points when you add a bean to the manager
 
     public void clear() {
         this..invalidateAll();
     }

Parameters:
name The name to match
Returns:

     public Set<Bean<?>> resolve(final String name) {
         return getCacheValue(name);
     }

    
Gets a string representation

Returns:
A string representation
 
     @Override
     public String toString() {
        StringBuilder buffer = new StringBuilder();
        buffer.append("Resolver\n");
        buffer.append("Resolved names points: ").append(.size()).append('\n');
        return buffer.toString();
