Field Summary

static 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 ObjectWrapper	DEFAULT_WRAPPER The default object wrapper implementation.
static ObjectWrapper	SIMPLE_WRAPPER Object wrapper that uses SimpleXXX wrappers only.

Method Summary

TemplateModel

wrap(java.lang.Object obj)

Field Detail

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.

Method Detail

wrap

TemplateModel wrap(java.lang.Object obj)
                   throws TemplateModelException

Returns:

a TemplateModel wrapper of the object passed in.

Throws:

TemplateModelException
