Examples of FileChangedReloadingStrategy

org.apache.commons.configuration.reloading.FileChangedReloadingStrategy

A reloading strategy that will reload the configuration every time its underlying file is changed.

This reloading strategy does not actively monitor a configuration file, but is triggered by its associated configuration whenever properties are accessed. It then checks the configuration file's last modification date and causes a reload if this has changed.

To avoid permanent disc access on successive property lookups a refresh delay can be specified. This has the effect that the configuration file's last modification date is only checked once in this delay period. The default value for this refresh delay is 5 seconds.

This strategy only works with FileConfiguration instances.
