• 2023-04-09 improve: #offerLeafNode: Use Files#copy(Path, Path, CopyOption...) if possible. It is faster if both files are in network on the same drive. No network data transmission clarified by OS level.
• 2014-12-12 Hartmut new: {@link CompareCtrl}: Comparison with suppressed parts especially comments.
• 2013-09-19 created. Comparison in callback routine of walkThroughFiles instead in the graphic thread.

Method Detail

start

public void start(FileRemote startNode,
                  FileRemoteCmdEventData co)

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.

offerLeafNode

public SortedTreeWalkerCallback.Result offerLeafNode(FileRemote fileRemote,
                                                     java.lang.Object oPath)

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.

finishedParentNode

public SortedTreeWalkerCallback.Result finishedParentNode(FileRemote dirRemote,
                                                          java.lang.Object oPath,
                                                          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:

dirRemote - the node which was walked through

oPath - Specific data presentation of the node

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

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.
