This test shows some advanced rules for annotations. It is important to highlight
that these rules may not be suitable for real applications, though. The problem here
is that the DictionaryPattern identifies annotations by their name, without further
analysis of the package in which the corresponding AnnotationType is defined.
In other words, a complete solution would need to distinguish the annotations
com.example.annotations.Foo and org.example.annotations.Foo. At this moment
JMerger cannot make such a distinction.
This example implements the following strategy (keep in mind that 'source' corresponds
to the new version while 'target' is the existing file, probably modified
by the developer):
- Annotations of members that have @generated in their Javadoc are always updated with
the contents of the source file
- Any annotation of an @generated member that only exists in the target is removed
- An @generated member that only exists in the target is commented out
-->
<!--
This dictionary pattern is used to identify all member marked with an @generated
javadoc annotation
-->
<merge:dictionaryPattern
name="Update"
select="Member/getComment"
match="@\s*(gen)erated\s*\n"/>
<!--
With this pull rule, the annotations of members marked as @generated are
replaced by the contents of the annotations in the source.
-->
<merge:pull
sourceGet="Annotation/getContents"
targetParentMarkup="^gen$"
targetPut="Annotation/setContents"/>
<!--
With this sweep rule, any annotation in the target that is not available in the
source is deleted.
-->
<merge:sweep parentMarkup="^gen$" select="Annotation"/>
<!--
With this sweep rule, any member in the target that is not available in the
source is commented out.
-->
<merge:sweep markup="^gen$" select="Member" action="comment"/>
</merge:options>
