All Known Implementing Classes:
FileEventActivitySource, FileEventSource
@ConfigurationDescription(properties={@Property(name="SearchDirectoryPath",description="The path of the directory which causes an event when a new file is inserted."),,,,,,,}) public interface PollingFileSource extends PollingSource<FileEvent>
An event source causing an event based on the presence of a file. This may be a file that has been stored to a special folder.
An ordinary implementation of this file source creates an event for each file (and possibly also a directory) present in the folder. This is good for mostly empty folders. Filters may apply for specific files. It is not advised to track the files internally and only create events for new files and ignore existing files. This should be rather solved with an event handler moving a file that has been successfully handled so that the file source does not find the file again.
