Interface NamespaceResolver

All Known Implementing Classes:
  UnifiedJEXL.TemplateContext

    public interface 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:
  2.1
