componentClass - The component class

authorizedRoles

public <T extends IRequestableComponent> Roles authorizedRoles(Class<T> componentClass)

Gets the roles that have a binding with the given component class.

Type Parameters:

T -

Parameters:

componentClass - the component class

the roles that have a binding with the given component class, or null if no entries are found
