Apache Tuscany SDO C++ M3
|
|
=========================
|
|
|
|
http://incubator.apache.org/tuscany
|
|
|
|
Tuscany is an effort undergoing incubation at the Apache Software Foundation
|
|
(ASF), sponsored by the Web Services PMC.
|
|
|
|
Incubation is required of all newly accepted projects until a further review
|
|
indicates that the infrastructure, communications, and decision making process
|
|
have stabilized in a manner consistent with other successful ASF projects.
|
|
|
|
While incubation status is not necessarily a reflection of the completeness or
|
|
stability of the code, it does indicate that the project has yet to be fully
|
|
endorsed by the ASF.
|
|
|
|
|
|
Getting Started
|
|
===============
|
|
|
|
Documentation describing the system requirements and the steps to install
|
|
Tuscany SDO C++ and run the samples can be found in the GettingStarted.html
|
|
file.

About Tuscany SDO for C++
|
|
=========================
|
|
|
|
Tuscany SDO is an implementation of the Service Data Objects for C++ 2.01
|
|
specification found at
|
|
http://www.osoa.org/display/Main/SDO+-+Previously+Published+Specifications
|
|
|
|
Supported SDO features
|
|
* All features are supported unless listed under the known restrictions
|
|
below. See the Service Data Objects for C++ 2.01 specification.
|
|
|
|
New features in this release
|
|
* 30-40% performance improvement
|
|
* Multiple bug fixes and internal enhancements
|
|
|
|
Known Restrictions
|
|
The implementation adheres closely to the specification, but there are a number
|
|
of features which did not make it into this release. These are documented
|
|
below.
|
|
|
|
Generic get/set:
|
|
The C++ implementation defines a set of access methods directly appropriate to
|
|
each Type. For example getString(), setString(), getBoolean(), setBoolean().
|
|
There is no generic get() method as there is no common base object to return -
|
|
unlike the java implementation which can return an Object.
|
|
|
|
Typesafe interface:
|
|
There is no code generation in this version, so there is no interface such that
|
|
a property called "Name" can be accessed via object->getName(). The name must
|
|
be accessed via object->getString("Name");
|
|
|
|
Change Summary Serialization:
|
|
Change summaries contain creations, deletions and modifications to data graphs.
|
|
The specification indicates that these will be serialized to XML such that
|
|
creations and deletions will become attributes of the change summary element,
|
|
whilst changes become elements within the change summary element. This
|
|
implementation saves all creations, deletions and changes as elements within
|
|
the change summary element.
|
|
|
|
Change Summary Undo:
|
|
The undo method of a change summary is not implemented.
|
|
|
|
Read-Only:
|
|
Read-only data elements are not supported by this implementation. Properties
|
|
may be set read-only, but the property may still be modified without an error.
|
|
|
|
Opposites:
|
|
Opposites are not supported by this implementation.
|
|
|
|
Date and Time:
|
|
Date support is limited to using a time_t. There are no calendar or duration
|
|
style objects, and no helpers for conversions.
|
|
|
|
BigDecimal and BigInteger:
|
|
The equivalent of the java BigDecimal and BigInteger objects are not
|
|
implemented.
|
|
|
|
NLS support:
|
|
Data objects may contain multi-byte data in the form of an SDO string, but
|
|
locale information is not stored with the data. The creation API only allows
|
|
properties and types to have ascii names (taking a char* as the name).
|
|
|
|
Inheritance:
|
|
Type inheritance is single only.
