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.
Since 2001 there is a Hyperwave SDK available. It
supports Java, JavaScript and C++. This PHP Extension
is based on the C++ interface. In order to activate the
hwapi support in PHP you will have to install the
Hyperwave SDK first.
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.

表格 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.
HW_API
HW_API_Object
HW_API_Attribute
HW_API_Error
HW_API_Content
HW_API_Reason
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.
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().
