6.3.0 (Jun 30, 2017)

Juneau 6.3.0 is a major update with significant new functionality for defining proxy interfaces against arbitrary 3rd-party REST interfaces.

##### org.apache.juneau

- New package: {@link oaj.http}.
- Support for dynamic beans. See @BeanProperty(name).
- New doc: 2.8 - Virtual Beans
- New doc: 2.13 - Comparison with Jackson
- All parsers now allow for numeric types with 'K'/'M'/'G' suffixes to represent kilobytes, megabytes, and gigabytes.

  // Example int i = JsonParser.DEFAULT.parse("123M"); // 123MB

- New/modified methods on ConfigFile:
  - ConfigFile.put(String,String,String,boolean)
  - ConfigFile.put(String,String,Object,Serializer,boolean,boolean)
  - ConfigFile.getObject(String,Type,Type...)
  - ConfigFile.getObject(String,Parser,Type,Type...)
  - ConfigFile.getObject(String,Class)
  - ConfigFile.getObject(String,Parser,Class)
  - ConfigFile.getObject(String,String,Type,Type...)
  - ConfigFile.getObject(String,String,Parser,Type,Type...)
  - ConfigFile.getObject(String,String,Class)
  - ConfigFile.getObject(String,String,Parser,Class)
  - ConfigFile.getObjectWithDefault(String,Object,Type,Type...)
  - ConfigFile.getObjectWithDefault(String,Parser,Object,Type,Type...)
  - ConfigFile.getObjectWithDefault(String,Object,Class)
  - ConfigFile.getObjectWithDefault(String,Parser,Object,Class)
- New ability to interact with config file sections with proxy interfaces with new method ConfigFile.getSectionAsInterface(String,Class).
- @BeanProperty annotation can now be applied to getters and setters defined on interfaces.
- New methods on {@link oaj.serializer.SerializerSession} and {@link oaj.parser.ParserSession} for retrieving context and runtime-override properties:
  - Session.getProperty(String)
  - Session.getProperty(String,String)
  - Session.getProperty(Class,String)
  - Session.getProperty(Class,String,Object)
- New org.apache.juneau.serializer.PartSerializer interface particularly tailored to HTTP headers, query parameters, form-data parameters, and path variables.
  Allows easy user-defined serialization of these objects.
  The interface can be used in the following locations:
  - org.apache.juneau.rest.client.RestClientBuilder.partSerializer(Class)
  - org.apache.juneau.remoteable.Path.serializer
  - org.apache.juneau.remoteable.Query.serializer
  - org.apache.juneau.remoteable.QueryIfNE.serializer
  - org.apache.juneau.remoteable.FormData.serializer
  - org.apache.juneau.remoteable.FormDataIfNE.serializer
  - org.apache.juneau.remoteable.Header.serializer
  - org.apache.juneau.remoteable.HeaderIfNE.serializer
- Across-the-board improvements to the URI-resolution support (i.e. how URIs get serialized).
  - New support for resolving URIs with the following newly-recognized protocols:
    - "context:/..." - Relative to context-root of the application.
    - "servlet:/..." - Relative to the servlet URI.
    - "request:/..." - Relative to the request URI.
    For example, currently we define HTML page links using variables and servlet-relative URIs...

    pages="{up:'$R{requestParentURI}', options:'?method=OPTIONS', upload:'upload'}"

    With these new protocols, we can define them like so:

    links="{top:'context:/', up:'request:/..' ,options:'servlet:/?method=OPTIONS', upload:'servlet:/upload'}"

    The old method of using variables and servlet-relative URIs will still be supported, but using these new protocols should (hopefully) be easier to understand.
    These protocols work on all serialized URL and URI objects, as well as classes and properties annotated with {@link oaj.annotation.URI @URI}.
  - New classes:
    - {@link oaj.UriContext}
    - {@link oaj.UriRelativity}
    - {@link oaj.UriResolution}
    - {@link oaj.UriResolver}
  - New configuration properties:
  - SerializerContext.SERIALIZER_uriContext
  - SerializerContext.SERIALIZER_uriRelativity
  - SerializerContext.SERIALIZER_uriResolution
  - SerializerContext.SERIALIZER_maxIndent
- New annotation property: @BeanProperty(value).
  The following two annotations are considered equivalent:

  @BeanProperty(name="foo") @BeanProperty("foo")

- Fixed a race condition in ClassMeta.
- URLENC_paramFormat has been moved to UonSerializer.UON_paramFormat, and the UON/URL-Encoding serializers will now always serialize all values as plain text.
  This means that arrays and maps are converted to simple comma-delimited lists.
- Listener APIs added to serializers and parsers:
  - {@link oaj.serializer.SerializerListener}
  - {@link oaj.serializer.SerializerBuilder#listener(Class)}
  - @RestResource(serializerListener)
  - RestConfig.serializerListener(Class)
  - {@link oaj.parser.ParserListener}
  - {@link oaj.parser.ParserBuilder#listener(Class)}
  - @RestResource(parserListener)
  - RestConfig.parserListener(Class)
  - RestClientBuilder.listeners(Class,Class)

- The {@link oaj.BeanContext#BEAN_debug} flag will now capture parser input and make it available through the ParserSession.getInputAsString() method so that it can be used in the listeners.
- Significant new functionality introduced to the HTML serializer.
  Lots of new options for customizing the HTML output.
  - New {@link oaj.html.annotation.Html#render() @Html(render)} annotation and {@link oaj.html.HtmlRender} class that allows you to customize the HTML output and CSS style on bean properties:
    Annotation can be applied to POJO classes and bean properties.
  - Several new properties for customizing parts of the HTML page:
    - HtmlDocSerializerContext.HTMLDOC_title
    - HtmlDocSerializerContext.HTMLDOC_description
    - HtmlDocSerializerContext.HTMLDOC_branding
    - HtmlDocSerializerContext.HTMLDOC_header
    - HtmlDocSerializerContext.HTMLDOC_nav
    - HtmlDocSerializerContext.HTMLDOC_aside
    - HtmlDocSerializerContext.HTMLDOC_footer
    - HtmlDocSerializerContext.HTMLDOC_noResultsMessage
    - HtmlDocSerializerContext.HTMLDOC_cssUrl
    - HtmlDocSerializerContext.HTMLDOC_css
    - HtmlDocSerializerContext.HTMLDOC_template
  - New interface {@link oaj.html.HtmlDocTemplate} that allows full control over rendering of HTML produced by {@link oaj.html.HtmlDocSerializer}.
- {@link oaj.annotation.NameProperty @NameProperty} and {@link oaj.annotation.ParentProperty @ParentProperty} can now be applied to fields.
- New properties on {@link oaj.BeanContext}:
  - BEAN_includeProperties
  - BEAN_excludeProperties
- New annotation property: @BeanProperty(format).
