The different functionalities of Gizmo(QP) make use of several object types, each dedicated to specific task. Not all are formal types, as some are no more than a working convention, e.g. the crumb data tuple. This sections demos a few of the these special object types.
${html.href('x', 'eXportable')}
QP implements an export as an informal 4-tuple.
Gizmo formalizes the eXportable type, that is equivalent
to a QP export except for the fact that it
is only a QP export if it passes contextual access control.
See module: gz.fill.exportable
${html.href('dhi', 'Dhi')}
The Dhi object for an export is contributed to by all
participants of a response, making complex DHTML pages easier
to build and debug, as well as simpler to render by the client.
See module: gz.fill.dhi
${html.href('crumb', 'Crumb')}
A 5-tuple, that contains navigation-pertinent information
about an export.
See module: gz.fill.directory
