All Implemented Interfaces:

XMLStreamConstants, XMLStreamReader, JsonConstants

Direct Known Subclasses:

GMLJsonStreamReader, SWEJsonStreamReader

public class JsonStreamReader
extends Object
implements XMLStreamReader, JsonConstants

Stream reader implementation for unmarshalling SWE metadata from JSON.
