XXXIX. Hyperwave API functions
Hyperwave has been developed at IICM in Graz. It started with the name Hyper-G and changed to Hyperwave when it was commercialised (in 1996).
Hyperwave is not free software. The current version, 5.5, is available at http://www.hyperwave.com/. A time limited version can be ordered for free (30 days).
See also the Hyperwave module.
Hyperwave is an information system similar to a database (HIS, Hyperwave Information Server). Its focus is the storage and management of documents. A document can be any possible piece of data that may as well be stored in file. Each document is accompanied by its object record. The object record contains meta data for the document. The meta data is a list of attributes which can be extended by the user. Certain attributes are always set by the Hyperwave server, other may be modified by the user.
The integration with Apache and possible other servers is already described in the Hyperwave module which has been the first extension to connect a Hyperwave Server.
The behaviour of these functions is affected by settings in php.ini.
Table 1. Hyperwave API configuration options
The API provided by the HW_API extension is fully object oriented. It is very similar to the C++ interface of the Hyperwave SDK. It consist of the following classes.
Each class has certain method, whose names are identical to its counterparts in the Hyperwave SDK. Passing arguments to this function differs from all the other PHP extensions but is close to the C++ API of the HW SDK. Instead of passing serval parameters they are all put into an associated array and passed as one paramter. The names of the keys are identical to those documented in the HW SDK. The common parameters are listed below. If other parameters are required they will be documented if needed.
