Method Detail

wrapIfNecessary

public static java.lang.Object wrapIfNecessary(java.lang.Object invocationResult)

Determine if, based on the rules, this invocation result should be wrapped into a ResultWrapper. The rules concerning wrapping are: - The result is primitive (Integer, Float, etc.) - The result is an object array - The result is a collection - Otherwise, the submitted result object

If the result is a collection, the collection is simplified by calling toArray, for easier validation

Parameters:

invocationResult -

Returns:

Wrapped result object if primitive or collection

                                           org.springframework.beans.PropertyValue propertyValue)

Retrieve the propertyValue from the bean wrapper given the specified rules. The rules are: - if the wrapper is a ResultWrapper, and no property name is specified, use the default property name "value" - if the property name is specified, use it - otherwise, no property name is used (this should fail)

Parameters:
