Andreas Veithen updated AXIOM-96:
---------------------------------
Fix Version/s: (was: 1.2.11)
1.2.9
> StreamingOMSerializer expands OMSourcedElement nodes
> ----------------------------------------------------
>
> Key: AXIOM-96
> URL: https://issues.apache.org/jira/browse/AXIOM-96
> Project: Axiom
> Issue Type: Bug
> Reporter: Rich Scheuerle
> Assignee: Rich Scheuerle
> Fix For: 1.2.9
>
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> Background:
> An OM tree may have one or more OMSourcedElement nodes in the tree. An
> OMSourcedElement represents an OMElement but contains its content in an
> alternative form (String, bytes, JAXB object etc.)
> The OMSourcedElement nodes allow OM to represent a message with a much
> flatter tree.
> Problem:
> If an OM tree containing OMSourcedElements is serialized with the
> StreamingOMSerializer, the OMSourcedElements are inadvertently expanded.
> This extra processing is slow and unnecessary.
> Solution:
> The StreamingOMSerializer uses an OMNavigator to walk the incoming
> XMLStreamReader events. When the OMNavigator encounters a OMSourcedElement,
> it expands the OMSourcedElement so that it can generated the XMLStreamReader
> events for the content.
> The solution is to add a property to the OMNavigator to allow it to tree
> OMSourcedElements as leaf objects. In such cases, the StreamingOMSerializer
> can gain access to the OMDataSource and write it out directly. This
> increases performance because it eliminates the expansion of the tree.
> I am working on a series of validation tests and a code solution.
