## Interface JexlContext.NamespaceResolver

- All Known Implementing Classes:
    ObjectContext
  Enclosing interface:
    JexlContext

      public static interface JexlContext.NamespaceResolver

  This interface declares how to resolve a namespace from its name; it is used by the interpreter during evalutation.

  In JEXL, a namespace is an object that serves the purpose of encapsulating functions; for instance, the "math" namespace would be the proper object to expose functions like "log(...)", "sinus(...)", etc.

  In expressions like "ns:function(...)", the resolver is called with resolveNamespace("ns").

  JEXL itself reserves 'jexl' and 'ujexl' as namespaces for internal purpose; resolving those may lead to unexpected results.

  Since:
    3.0
