                  org.apache.servicemix.vfs.VFSPollingEndpoint

All Implemented Interfaces:

Endpoint, VFSEndpointType

public class VFSPollingEndpoint
extends PollingEndpoint
implements VFSEndpointType

A polling endpoint that looks for a file or files in a virtual file system and sends the files to a target service (via the JBI bus), deleting the files by default when they are processed. The polling endpoint uses a file marshaler to send the data as a JBI message; by default this marshaler expects XML payload. For non-XML payload, e.g. plain-text or binary files, use an alternative marshaler such as the org.apache.servicemix.components.util.BinaryFileMarshaler
