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
This extension has been moved to the PECL repository and is no longer bundled with
PHP as of PHP 5.2.0.
Since 2001 there is a Hyperwave SDK available. It supports Java,
In order to activate the hwapi support in PHP you will have to install
the Hyperwave SDK first.
After installing the Hyperwave SDK, configure PHP with
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.

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.
Some basic classes like HW_API_String
, etc., which exist in the
Hyperwave SDK have not been implemented since PHP has powerful
replacements for them.
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 several parameters they are all put into
an associated array and passed as one parameter. 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.
objectIdentifier The name or id of an object,
e.g. "rootcollection", "0x873A8768 0x00000002".
parentIdentifier The name or id of an object
which is considered to be a parent.
object An instance of class HW_API_Object.
parameters An instance of class HW_API_Object.
version The version of an object.
mode An integer value determine the way an
operation is executed.
attributeSelector Any array of strings, each
containing a name of an attribute. This is used if you retrieve the
object record and want to include certain attributes.
objectQuery A query to select certain object
out of a list of objects. This is used to reduce the number of objects
which was delivered by a function like
hw_api->children() or hw_api->find().
Methods returning boolean can return TRUE, FALSE or
