Rebex.Common Console-based log writer that writes log messages to the console. Common base class for log writers. A derived class must override either the method or both Write methods. Defines methods and properties all log writers must implement. Write a message into the log. Message level. Logging object type. Logging object ID. Logging area. Message. Write a message and data block into the log. Message level. Logging object type. Logging object ID. Logging area. Message. Data block. Data offset. Date length. Get or set the log level - only log messages with log level equal to or greater than the specified one. Log level. Creates a new instance of . Closes the log writer. Releases unmanaged and managed resources (depending on the scenario). If is false, the method has been called from the finalizer and should not reference other objects (therefore only unmanaged resources can be disposed). True indicates that the method has been called via IDisposable.Dispose. False indicates that it has been called by the finalizer. Writes a message into the log. Message level. Logging object type. Logging object ID. Logging area. Message. Writes a message and data block into the log. Message level. Logging object type. Logging object ID. Logging area. Message. Data block. Data offset. Date length. Appends the specified message text into a text-based log. This method is only called by method and is only used by text-based loggers. Full message info. Disposes the object. Gets or sets the log level - only log messages with log level equal to or greater than the specified one. Log level. Get a value indicating whether the log writer is closed. True when log writer is closed. False if log writer is opened and ready for writing. Implementation in this base class returns false, as the close method actually does not close any resource.

Flatten means to don't persist directory structure. For example if used to upload files "A/a.txt" and "B/b.txt" to the "/data" directory on a FTP server, files "a.txt" and "b.txt" are uploaded directly into the "/data" directory (directories "A" and "B" are not created in the "/data" directory).

Specifies how a search pattern is treated (how to traverse a hierarchy of directories). See Using TraversalMode blog post for samples. Performs shallow search for files and directories; do recursive transfer of matching directories.
Shallow search means that items are searched only in the first level of given directory.
If the pattern matches a file, the file is processed.
If the pattern matches a directory, all files and subdirectories are processed. Performs shallow search for files and directories; do non-recursive transfer of matching directories.
Shallow search means that items are searched only in the first level of given directory.
If the pattern matches a file, the file is processed.
If the pattern matches a directory, only the directory itself is processed (without any content = empty directory will be created). Performs shallow search for files only. This is the same as mode, but only files are processed.
Shallow search means that files are searched only in the first level of given directory. Performs deep search for files only. This is like DOS xcopy deep file search.
Deep search means that files are searched in the given directory and also in all its subdirectories.
However, if this mode is used in GetItems method, returned collection will also contains directories where the files were found. This behavior is useful in situations where you need to prepare the containing directory before the file is processed. To get only files, just use Linq like this: collection.Where(item => !item.IsDirectory) Specifies the default action to perform when a target file already exists. However, the default action can still be changed using the ProblemDetected event. Existing files are to cause the whole multi-file transfer to be canceled and an exception to be raised. Existing files are to be always skipped. Existing files are to be always overwritten. Existing files are to be overwritten if they are older than source files. This is strongly discouraged because modification dates are often misreported by FTP and SFTP servers, making this mode highly unreliable. We strongly recommend to use a different mode or develop a custom solution using the ProblemDetected event. Existing files with different sizes are to be overwritten. Existing files are to be resumed if they are smaller than source files. Existing files are to be renamed according the pattern "filename[number].extension". You can still change the generated name using the ProblemDetected event and the method. Existing files with different checksum are to be overwritten.
Works on FTP and ZIP only. ZIP uses CRC-32 always; FTP uses checksums provided by the server (some FTP servers support no checksums). Specifies behavior on links and reparse points in multi-file operations. Detected links are to be resolved and processed - however, this can still be changed by ProblemDetected handler.
