aoqi@0: * This class creates a read-only {@link Map} view that aoqi@0: * gets exposed to client applications after an invocation aoqi@0: * is complete. aoqi@0: * aoqi@0: *

aoqi@0: * The design goal of this class is to make it efficient aoqi@0: * to create a new {@link ResponseContext}, at the expense aoqi@0: * of making some {@link Map} operations slower. This is aoqi@0: * justified because the response context is mostly just aoqi@0: * used to query a few known values, and operations like aoqi@0: * enumeration isn't likely. aoqi@0: * aoqi@0: *

aoqi@0: * Some of the {@link Map} methods requre this class to aoqi@0: * build the complete {@link Set} of properties, but we aoqi@0: * try to avoid that as much as possible. aoqi@0: * aoqi@0: * aoqi@0: *

aoqi@0:  * TODO: are we exposing all strongly-typed fields, or
aoqi@0:  * do they have appliation/handler scope notion?
