java.lang.Object com.fasterxml.jackson.core.JsonStreamContext
public abstract class JsonStreamContext
Shared base class for streaming processing contexts used during reading and writing of Json content using Streaming API. This context is also exposed to applications: context object can be used by applications to get an idea of relative position of the parser/generator within json content being processed. This allows for some contextual processing: for example, output within Array context can differ from that of Object context.
