  • Method Details

    • getClassNames

      Collection<String> getClassNames()
      Returns a readonly collection of the logic names of the class (never null). Note: it is the name to resolve class, not the real class name. In other words, it is the logical name maintained by this function mapper.

    • resolveClass

      Class<?> resolveClass(String name) throws XelException
      Resolves a class with the specified logic name, or null if not found.

      Note: not all EL evaluator support resolveClass(java.lang.String). JSP 2.0/2.1 EL-based expression factories don't support this method. You can check ExpressionFactory.isSupported(int) for this support.

      Returns:
      the class of the specified logic name.
      Throws:
      XelException
