This schema file defines faults that may be raised by the
|
|
OpenStack Compute API. These faults are derived from the <a
|
|
href="#type_ComputeAPIFault" title="See definition of
|
|
ComputeAPIFault">ComputeAPIFault</a>. Most faults extend this
|
|
type without adding any additional attributes or elements.
|
|
The only exceptions is the <a href="#type_OverLimitAPIFault"
|
|
title="See definition of
|
|
OverLimitAPIFault">OverLimitAPIFault</a> which adds a
|
|
<strong>retryAt</strong> attribute and the <a
|
|
href="#type_AsyncAPIFault" title="See definition of
|
|
AsyncAPIFault">AsyncAPIFault</a> which adds a
|
|
<strong>created</strong> timestamp. Because all faults extend
|
|
a standard base type, it should be possible to capture all API
|
|
faults with a single <code>catch</code> statement.
|
|
</p>
|
|
<p>
|
|
Faults are associated with a default HTTP status code that
|
|
corresponds to the particular fault type. For example an <a
|
|
href="#element_itemNotFound" title="see definition of
|
|
itemNotFound"><itemNotFound></a> element is associated
|
|
with the HTTP status code 404. Some elements, the <a
|
|
href="#element_computeFault" title="see definition of
|
|
computeFault"><computeFault></a> element for
|
|
example, may be associated with multiple status codes. It is
|
|
also possible for multiple fault elements to be associated
|
|
with the same default code. The examples below showcase the
|
|
default status codes for each element type. Note that these
|
|
default codes are not part of the formal schema. In practice,
|
|
however, an element type will likely be associated with its
|
|
corresponding default status code.
