  • Field Summary

    Fields
    Modifier and Type
    Field
    Description
    static final ObjectWrapper
    BEANS_WRAPPER
    An ObjectWrapper that works similarly to SIMPLE_WRAPPER, but exposes the objects methods and JavaBeans properties as hash elements and custom handling for Java Maps, ResourceBundles, etc.
    static final ObjectWrapper
    DEFAULT_WRAPPER
    The default object wrapper implementation.
    static final ObjectWrapper
    SIMPLE_WRAPPER
    Object wrapper that uses SimpleXXX wrappers only.

    • BEANS_WRAPPER

      static final ObjectWrapper BEANS_WRAPPER
      An ObjectWrapper that works similarly to SIMPLE_WRAPPER, but exposes the objects methods and JavaBeans properties as hash elements and custom handling for Java Maps, ResourceBundles, etc.

    • DEFAULT_WRAPPER

      static final ObjectWrapper DEFAULT_WRAPPER
      The default object wrapper implementation. Wraps Maps as SimpleHash and Lists as SimpleSequences, Strings and Numbers as SimpleScalar and SimpleNumber respectively. Other objects are beans-wrapped, thus exposing reflection-based information.

    • SIMPLE_WRAPPER

      static final ObjectWrapper SIMPLE_WRAPPER
      Object wrapper that uses SimpleXXX wrappers only. This wrapper has far more restrictive semantics. It behaves like the DEFAULT_WRAPPER, but for objects that it does not know how to wrap as a SimpleXXX, it throws an exception. It makes no use of reflection-based exposure of methods.
