Package org.refcodes.net

Interface HttpFields<B extends HttpFields<B>>

Type Parameters:

B - the generic type

All Superinterfaces:

java.util.Map<java.lang.String,java.util.List<java.lang.String>>

All Known Subinterfaces:

FormFields, HeaderFields<C,B>, RequestHeaderFields, ResponseHeaderFields

All Known Implementing Classes:

AbstractHeaderFields, AbstractHttpFields, FormFieldsImpl, RequestHeaderFieldsImpl, ResponseHeaderFieldsImpl

public interface HttpFields<B extends HttpFields<B>>
extends java.util.Map<java.lang.String,java.util.List<java.lang.String>>

Various key/value "collections" we run across when we develop HTTP based applications may have more then one value for one key. Such "collections" in this package are the HeaderFields as well as the FormFields. This interface represents this kind of data structure providing some common convenience methods.
