ZipUpload: provide hooks for extending
--------------------------------------
Key: MAGNOLIA-3500
URL: http://jira.magnolia-cms.com/browse/MAGNOLIA-3500
Project: Magnolia
Issue Type: Improvement
Components: admininterface
Affects Versions: 4.4.1, 4.4, 4.3.8
Environment: N/A
Reporter: Richard Unger
Assignee: Philipp Bärfuss
While creating my image-metadata module, I was looking for a way to "hook" into
the Zip-Upload in DMS.
Unfortunately, there is currently no way to extend the ZipUpload with custom
functionality, other than replacing the whole class.
My Use-Case is the following: when a user uploads a ZIP-File with images, I
want to automatically perform my metadata import (EXIF & XMP tags) for all
contained images.
Problem is that the class info.magnolia.module.dms.gui.ZipUpload (DMS module)
does not provide a hook which is called per processed file, and declares it's
methods processFile and processEntry as private, making it impossible to extend
the class.
Solution:
Add a method like
protected void postProcessFile(Content dmsNode){}
to class ZipUpload, and make sure it gets called from within processFile for
each file handled.
Alternatively, just make processFile and processEntry protected rather than
private.
