-------------------------------------
Summary: Enable streaming of the root part of a MIME message using
the Attachments API
Key: AXIOM-416
URL: https://issues.apache.org/jira/browse/AXIOM-416
Project: Axiom
Issue Type: Improvement
Components: API
Affects Versions: 1.2.13
Reporter: Andreas Veithen
Assignee: Andreas Veithen
Fix For: 1.2.14
Before version 1.2.13, Axiom always loaded the root (SOAP) part of a MIME
message into memory. Axiom 1.2.13 introduced support for streaming of the root
part. If that feature is used, the root part will not be loaded into memory
unless an attempt is made to access another part of the MIME message (in which
case Axiom buffers the remaining - i.e. unconsumed - content of the root part).
However, this feature is only supported by the
OMXMLBuilderFactory#createSOAPModelBuilder(Attachments) and
OMXMLBuilderFactory#createSOAPModelBuilder(OMMetaFactory, Attachments) APIs.
These methods are not used by Axis2, and cannot be used because Axis2 relies
its own API (org.apache.axis2.builder.Builder) to process the root part, in
particular to support SwA (while OMXMLBuilderFactory only supports MTOM). To
allow Axis2 to take advantage of the feature, it is necessary to introduce a
new method in the Attachments class.
The proposal is to add a method with the following signature:
InputStream getRootPartInputStream(boolean preserve)
If preserve == true, the method will behave in the same way as the existing
getRootPartInputStream() method. If preserve == false, then streaming will be
enabled.
