Constructor Detail

FileRemoteCallbackSearch

FileRemoteCallbackSearch(FileRemote dir1,
                         byte[] search,
                         FileRemoteWalkerCallback callbackUser,
                         EventWithDst<FileRemoteProgressEvData,?> evBack)

Constructs an instance to execute a comparison of directory trees.

Parameters:

dir1 - One directory which contains a file tree. All files are compared with dir2

dir2 - The other directory to compare

callbackUser - Maybe null. If given, on each directory entry, exit and file the callback will be invoked with the handled directory or file. The second argument is an boxed Integer, which contains the bits from FileMark to inform what is with that file.

timeOrderProgress - maybe null. If given this timeOrder is used to show the progression of the comparison. The timeOrder is set with data

Method Detail

start

public void start(FileRemote startDir,
                  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 dir,
                                                       java.lang.Object oPath,
                                                       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>

oPath - 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 file,
                                                          java.lang.Object oPath,
                                                          java.lang.Object oWalkInfo)

Checks whether all files are compared or whether there are alone files.

Specified by:

finishedParentNode in interface SortedTreeWalkerCallback<FileRemote,FileRemoteCmdEventData>

Parameters:

file - the node which was walked through

oPath - Specific data presentation of the node

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

offerLeafNode

public SortedTreeWalkerCallback.Result offerLeafNode(FileRemote file,
                                                     java.lang.Object info)

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.

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.

searchInFile

int searchInFile(FileRemote file1)

Compare two files.

Parameters:

file1 -

file2 - both file should be exist. It is tested before.

Returns:

either FileMark.cmpContentEqual or

Since:

2015-09-05 returns comparison result, does not set bits in the file mask. Done on calling level.

compareFileContent

boolean compareFileContent(FileRemote file1,
                           FileRemote file2)
                    throws java.io.IOException

Compare two files.

Parameters:

file -

Throws:

java.io.FileNotFoundException

readIgnoreComment

private java.lang.String readIgnoreComment(java.io.BufferedReader reader)
                                    throws java.io.IOException

Throws:

java.io.IOException

finished

public void finished(FileRemote startDir)

Description copied from interface: SortedTreeWalkerCallback

Invoked after finishing the walking through.

Specified by:

finished in interface SortedTreeWalkerCallback<FileRemote,FileRemoteCmdEventData>
