clobber option for FileComponent
--------------------------------
Key: CAMEL-1653
URL: https://issues.apache.org/activemq/browse/CAMEL-1653
Project: Apache Camel
Issue Type: New Feature
Components: camel-core
Affects Versions: 2.0.0
Reporter: Joe Gottman
Priority: Minor
FileComponent currently has an append option, which is set to true for File
Producers to make the Producer write to the end of an existing file, and false
to make it overwrite an existing file. However, sometimes it is an error for
it to do anything to change an existing file. Would it be possible to add a
clobber option to the FileComponent which defaults to true but when set to
false prevents the File Producer from modifying an existing file? It should
probably throw some kind of Camel Exception when it attempts to write to a file
that already exists. If desired, the Route can then catch this Exception and
handle it, for instance by trying to write the file to a different location.
This option might also be useful for some other Producer components for the
same reason.
