Method Detail

parseAttributes

public static void parseAttributes(Element element,
                                   org.springframework.beans.factory.support.BeanDefinitionBuilder builder,
                                   AttributeCallback[] callbacks)

Generic attribute callback. Will parse the given callback array, w/o any standard callback.

Parameters:

element - XML element

builder - current bean definition builder

callbacks - array of callbacks (can be null/empty)

parseCustomAttributes

public static void parseCustomAttributes(Element element,
                                         org.springframework.beans.factory.support.BeanDefinitionBuilder builder,
                                         AttributeCallback[] callbacks)

Dedicated parsing method that uses the following stack:

1. user given AttributeCallbacks
2. StandardAttributeCallback
3. PropertyRefAttributeCallback
4. ConventionCallback

Parameters:

element - XML element

builder - current bean definition builder

callbacks - array of callbacks (can be null/empty)

parseCustomAttributes

public static void parseCustomAttributes(Element element,
                                         org.springframework.beans.factory.support.BeanDefinitionBuilder builder,
                                         AttributeCallback callback)

Derivative for #parseCustomAttributes(Element, BeanDefinitionBuilder, org.eclipse.gemini.blueprint.internal.config.ParserUtils.AttributeCallback[]) accepting only one AttributeCallback.

Parameters:

element - XML element

builder - current bean definition builder

callback - attribute callback, can be null

mergeCallbacks

public static AttributeCallback[] mergeCallbacks(AttributeCallback[] callbacksA,
                                                 AttributeCallback[] callbacksB)

convertClassesToStrings

public static Set<?> convertClassesToStrings(Set<?> parsedClasses)

Utility method used for maintaining backwards compatibility by converting Class objects to String (using their class names). Used by importer and exporter parsing to set the 'interfaces' property.

Parameters:

parsedClasses - collection of parsed classes

Returns:

a collection of converted (if necessary) metadata
