public static final String EL_RESOLVER_COMPARATOR

Define a custom comparator class used to sort the ELResolvers.

This is useful when it is necessary to put an ELResolver on top of other resolvers. Note set this param override the default ordering described by JSF spec section 5.

Filters the ELResolvers with a custom Predicate provided by the user.

Parameters:

resolvers - list of ELResolvers

scope - scope of ELResolvers (Faces,JSP)

Returns:

Iterable instance of Iterable containing filtered ELResolvers
