PofExtractor (Coherence Spring Docs 3.3.1 API)

```
@Inherited
@ExtractorBinding
@Documented
@Retention(RUNTIME)
@Repeatable(Extractors.class)
public @interface PofExtractor
```
A ExtractorBinding annotation representing a PofExtractor.
This annotation can be used to define an extractor that extracts and attribute from a POF stream based on an array of integer property indices, in which case the type is optional, or a property path based on serialized field names concatenated using period (ie. address.city, in which case type() attribute must be set as well.
The latter approach can only be used if the specified type is annotated with a @PortableType annotation and has been instrumented using PortableTypeGenerator (typically via pof-maven-plugin).
Either index() or path() must be specified within this annotation in order for it to be valid.
