Class FileRemoteWalkerCallbackDelete

java.lang.Object

org.vishia.event.EventConsumerAwait<FileRemoteProgressEvData,FileRemoteCmdEventData>

org.vishia.fileRemote.FileRemoteProgressEventConsumer

org.vishia.fileRemote.FileRemoteWalkerCallbackDelete

All Implemented Interfaces:

EventConsumer, FileRemoteWalkerCallback, SortedTreeWalkerCallback<FileRemote,FileRemoteCmdEventData>

public class FileRemoteWalkerCallbackDelete
extends FileRemoteProgressEventConsumer
implements FileRemoteWalkerCallback

This callback operations are used to delete files from walking to the FileRemote instances using FileRemote#walkLocal(org.vishia.fileRemote.FileRemoteCmdEventData.Cmd, FileRemote, int, int, String, int, int, FileRemoteWalkerCallback, FileRemoteCmdEventData, int, org.vishia.event.EventWithDst) An instance of this class is used for callback. For the deletion itself it calls an operations of FileRemoteAccessor to delete on the device. Either one file is deleted, or a directory, and then with all children should be deleted.

Method Detail

start

public void start(FileRemote startNode,
                  FileRemoteCmdEventData startInfo)

Description copied from interface: SortedTreeWalkerCallback

Invoked before start of a walk through the tree.

Specified by:

start in interface SortedTreeWalkerCallback<FileRemote,FileRemoteCmdEventData>

offerParentNode

public SortedTreeWalkerCallback.Result offerParentNode(FileRemote parentNode,
                                                       java.lang.Object data,
                                                       java.lang.Object oWalkInfo)

Description copied from interface: SortedTreeWalkerCallback

Invoked on start on walking through a parent node which have children. It may be a directory inside a file tree. If this method is invoked for a node, the #offerLeafNode(TypeNode) is not invoked.

Specified by:

offerParentNode in interface SortedTreeWalkerCallback<FileRemote,FileRemoteCmdEventData>

data - Specific data presentation of the node

oWalkInfo - internal possible information about walking, depending on usage.

Returns:

information to abort, maybe boolean.

finishedParentNode

public SortedTreeWalkerCallback.Result finishedParentNode(FileRemote parentNode,
                                                          java.lang.Object data,
                                                          java.lang.Object oWalkInfo)

Description copied from interface: SortedTreeWalkerCallback

Invoked on end of walking through a parent node.

Specified by:

finishedParentNode in interface SortedTreeWalkerCallback<FileRemote,FileRemoteCmdEventData>

Parameters:

parentNode - the node which was walked through

data - Specific data presentation of the node

oWalkInfo - internal possible information about walking, depending on usage.

offerLeafNode

public SortedTreeWalkerCallback.Result offerLeafNode(FileRemote leafNode,
                                                     java.lang.Object leafNodeData)

Description copied from interface: SortedTreeWalkerCallback

Invoked for any node which has no children or which is not processed because the depth of walking through the tree is reached. It is called in opposite to #offerLeafNode(Object), only one of both is called for a node. For example it is invoked for a sub directory only if the depth is reached and #offerParentNode(TypeNode) is not called.

Specified by:

offerLeafNode in interface SortedTreeWalkerCallback<FileRemote,FileRemoteCmdEventData>

Returns:

information to abort or continue.

finished

public void finished(FileRemote startNode)

Description copied from interface: SortedTreeWalkerCallback

Invoked after finishing the walking through.

Specified by:

finished in interface SortedTreeWalkerCallback<FileRemote,FileRemoteCmdEventData>

shouldAborted

public boolean shouldAborted()

Description copied from interface: SortedTreeWalkerCallback

Returns true if the tree walking should be terminated respectively aborted. This routine should be called in any walk tree routine. The aborted state should be set from outside in the implementation classes.

Specified by:

shouldAborted in interface SortedTreeWalkerCallback<FileRemote,FileRemoteCmdEventData>

Returns:

true if should terminated.
