java.lang.Object

org.eclipse.jetty.util.Fields

All Implemented Interfaces:

Iterable<Fields.Field>

public class Fields
extends Object
implements Iterable<Fields.Field>

A container for name/value pairs, known as fields.

A Fields.Field is composed of a name string that can be case-sensitive or case-insensitive (by specifying the option at the constructor) and of a case-sensitive set of value strings.

The implementation of this class is not thread safe.
