Nested Class Summary

static interface	ParserUtils.AttributeCallback Wrapper callback used for parsing attributes (one at a time) that have are non standard (ID, LAZY-INIT, DEPENDS-ON).
static class	ParserUtils.ConventionCallback Callback relying on 'Spring' conventions.
static class	ParserUtils.PropertyRefAttributeCallback Convention callback that transforms "<property-name>-ref" attributes into a bean definition that sets the give <property-name> to a bean reference pointing to the attribute value.
static class	ParserUtils.StandardAttributeCallback Standard attribute callback.

Method Detail

parseAttributes

public static void parseAttributes(Element element,
                                   BeanDefinitionBuilder builder,
                                   ParserUtils.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,
                                         BeanDefinitionBuilder builder,
                                         ParserUtils.AttributeCallback[] callbacks)

Dedicated parsing method that uses the following stack:

1. user given ParserUtils.StandardAttributeCallbacks
2. ParserUtils.StandardAttributeCallback
3. ParserUtils.PropertyRefAttributeCallback
4. ParserUtils.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,
                                         BeanDefinitionBuilder builder,
                                         ParserUtils.AttributeCallback callback)

Derivative for #parseCustomAttributes(Element, BeanDefinitionBuilder, org.springframework.osgi.internal.config.ParserUtils.AttributeCallback[]) accepting only one ParserUtils.StandardAttributeCallback.

Parameters:

element - XML element

builder - current bean definition builder

callback - attribute callback, can be null

initOsgiDefaults

public static OsgiDefaultsDefinition initOsgiDefaults(Document document)

Initialize OSGi defaults.

Parameters:

document - XML document

Returns:

initialized OsgiDefaultsDefinition instance

initOsgiDefaults

public static OsgiDefaultsDefinition initOsgiDefaults(Element root)

Initialize OSGi defaults.

Parameters:

root - root document element

Returns:

initialized OsgiDefaultsDefinition instance

mergeCallbacks

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