Class CollectionConverter

java.lang.Object
  gov.nasa.arc.brahms.vm.api.convert.CollectionConverter

All Implemented Interfaces:

IConverter

public class CollectionConverter
extends java.lang.Object
implements IConverter

CollectionConverter handles the conversion between Java and Brahms collections. A Java collection is generally converted to a Brahms relation unless the values in the collection are of a primitive or enum type in which case the values are converted to a Brahms map (since relations do not support primitive types). A collection mixing both primitive and concept values is mapped to a Brahms map.
