Description
Sometimes it would be nice if the RSB resource holding classes like Listener, Informer, LocalServer and RemoteServer would implement the java.lang.AutoClosable interface to be usable in the try-with-resources constructs available since Java 7.
Same would go for pythons "with" statement, e.g. implementing enter() and exit() to activate and deactivate the object.

implemented close method

#1 Updated by J. Wienke almost 8 years ago
For python this is already supported.
#2 Updated by J. Wienke almost 8 years ago
After reading https://stackoverflow.com/questions/25190347/does-autocloseable-close-method-break-backward-compatibilty-rule-of-java it seems to be possible to implement the new java 7 AutoCloseable interface in a backwards-compatible fashion by implementing Closeable. Therefore we can extend our participants to implement Closeable and have immediate support fir try-with-resource blocks in java 7.
