Interface AbstractInboundRemoteFileSystemSychronizer.EntryAcknowledgmentStrategy<T>

Type Parameters:

T - the entry type (file, sftp, ftp, ...)

Enclosing class:

AbstractInboundRemoteFileSystemSychronizer<T>

public static interface AbstractInboundRemoteFileSystemSychronizer.EntryAcknowledgmentStrategy<T>

Strategy interface to expose a hook for dispatching, moving, or deleting the file once it's been delivered. This will typically be a NOOP for the implementation. Adapters should (for consistency) expose an attribute dictating whether the adapter will delete the source entry on the remote file system. This is the file-system version of an ack-mode. Future implementations should consider exposing a custom attribute that plugs a custom AbstractInboundRemoteFileSystemSychronizer.EntryAcknowledgmentStrategy into the pipeline and also some more advanced scenarios (i.e., 'move file to another folder on delete ', or 'rename on delete')

Method Summary

void	acknowledge(java.lang.Object useful, T msg) Semantics are simple.

Method Detail

acknowledge

void acknowledge(java.lang.Object useful,
                 T msg)
                 throws java.lang.Exception

Semantics are simple. You get a pointer to the entry just processed and any kind of helper data you could ask for. Since the strategy is a singleton and the clients you might ask for as context data are pooled, it's not recommended that you try to cache them.

Parameters:

useful - any context data

msg - the data / file / entry you want to process -- specific to sublcasses

Throws:

java.lang.Exception - thrown for any old reason
