SftpClient
```
public SftpClient(SshClient ssh,
          int Max_Version)
           throws SftpStatusException,
                  SshException,
                  ChannelOpenException
```
Constructs the SFTP client with a given channel event listener.

Parameters:
ssh - the SshClient instance
Max_Version - the maximum SFTP protocol version to use

Throws:

SftpStatusException

SshException

ChannelOpenException

Method Detail

setBlockSize
```
public void setBlockSize(int blocksize)
```
Sets the block size used when transferring files, defaults to the optimized setting of 32768. You should not increase this value as the remote server may not be able to support higher blocksizes.

Parameters:
blocksize -

getSubsystemChannel
```
public SftpSubsystemChannel getSubsystemChannel()
```
Returns the instance of the SftpSubsystemChannel used by this class

Returns:
the SftpSubsystemChannel instance

setTransferMode
```
public void setTransferMode(int transferMode)
```
Sets the transfer mode for current operations. The valid modes are:

MODE_BINARY - Files are transferred in binary mode and no processing of text files is performed (default mode).

MODE_TEXT - For servers supporting version 4+ of the SFTP protocol files are transferred in text mode. For earlier protocol versions the files are transfered in binary mode but the client performs processing of text; if files are written to the remote server the client ensures that the line endings conform to the remote EOL mode set using setRemoteEOL(int). For files retrieved from the server the EOL policy is based upon System policy as defined by the "line.seperator" system property.

Parameters:
transferMode - int

setRemoteEOL
```
public void setRemoteEOL(int eolMode)
```
When connected to servers running SFTP version 3 (or less) the remote EOL type needs to be explicitly set because there is no reliable way for the client to determine the type of EOL for text files. In versions 4+ a mechanism is provided and this setting is overridden.

Valid values for this method are EOL_CRLF (default), EOL_CR, and EOL_LF.

Parameters:
eolMode - int

getTransferMode
```
public int getTransferMode()
```
Returns:
int

setBufferSize
```
public void setBufferSize(int buffersize)
```
Set the size of the buffer which is used to read from the local file system. This setting is used to optimize the writing of files by allowing for a large chunk of data to be read in one operation from a local file. The previous version simply read each block of data before sending however this decreased performance, this version now reads the file into a temporary buffer in order to reduce the number of local filesystem reads. This increases performance and so this setting should be set to the highest value possible. The default setting is negative which means the entire file will be read into a temporary buffer.

Parameters:
buffersize -

setMaxAsyncRequests
```
public void setMaxAsyncRequests(int asyncRequests)
```
Set the maximum number of asynchronous requests that are outstanding at any one time. This setting is used to optimize the reading and writing of files to/from the remote file system when using the get and put methods. The default for this setting is 100.

Parameters:
asyncRequests -

umask

public int umask(int umask)

Sets the umask used by this client.

 To give yourself full permissions for both files and directories and
 prevent the group and other users from having access:
 
   umask(077);
 
 This subtracts 077 from the system defaults for files and directories
 666 and 777. Giving a default access permissions for your files of
 600 (rw-------) and for directories of 700 (rwx------).
 
 To give all access permissions to the group and allow other users read
 and execute permission:
 
   umask(002);
 
 This subtracts 002 from the system defaults to give a default access permission
 for your files of 664 (rw-rw-r--) and for your directories of 775 (rwxrwxr-x).
 
 To give the group and other users all access except write access:
 
   umask(022);
 
 This subtracts 022 from the system defaults to give a default access permission
 for your files of 644 (rw-r--r--) and for your directories of 755 (rwxr-xr-x).

Parameters:: umask -
Returns:: the previous umask value

openFile

public SftpFile openFile(String fileName)
                  throws SftpStatusException,
                         SshException

Throws:: SftpStatusException; SshException

cd
```
public void cd(String dir)
        throws SftpStatusException,
               SshException
```
Changes the working directory on the remote server, or the user's default directory if null or any empty string is provided as the directory path. The user's default directory is typically their home directory but is dependent upon server implementation.

Parameters:
dir - the new working directory

Throws:

IOException - if an IO error occurs or the file does not exist

SftpStatusException

SshException

getDefaultDirectory

public String getDefaultDirectory()
                           throws SftpStatusException,

Returns:: String
Throws:: SftpStatusException; SshException

public void cdup()
          throws SftpStatusException,
                 SshException

Download the remote files to the local computer

When RegExpSyntax is set to NoSyntax the getFiles() methods act identically to the get() methods except for a different return type.

When RegExpSyntax is set to GlobSyntax or Perl5Syntax, getFiles() treats 'remote' as a regular expression, and gets all the files in 'remote''s parent directory that match the pattern. The default parent directory of remote is the remote cwd unless 'remote' contains file seperators(/).

Examples can be found in SftpConnect.java
Code Example:
```
 // change reg exp syntax from default SftpClient.NoSyntax (no reg exp matching)
 // to SftpClient.GlobSyntax
 sftp.setRegularExpressionSyntax(SftpClient.GlobSyntax);
 // get all .doc files with 'rfc' in their names, in the 'docs/unsorted/' folder
 // relative to the remote cwd, and copy them to the local cwd.
 sftp.getFiles("docs/unsorted/*rfc*.doc");
 
```
Parameters:
remote - the regular expression path to the remote file

Returns:
the downloaded files' attributes

Throws:

FileNotFoundException

putFiles
```
public void putFiles(String local)
              throws FileNotFoundException,
                     SftpStatusException,
                     SshException,
                     TransferCancelledException
```
Upload the contents of an InputStream to the remote computer.

When RegExpSyntax is set to NoSyntax the putFiles() methods act identically to the put() methods except for a different return type.

When RegExpSyntax is set to GlobSyntax or Perl5Syntax, putFiles() treats 'local' as a regular expression, and gets all the files in 'local''s parent directory that match the pattern. The default parent directory of local is the local cwd unless 'local' contains file seperators.

Examples can be found in SftpConnect.java
Code Example:
```
 // change reg exp syntax from default SftpClient.NoSyntax (no reg exp matching)
 // to SftpClient.GlobSyntax
 sftp.setRegularExpressionSyntax(SftpClient.GlobSyntax);
 // put all .doc files with 'rfc' in their names, in the 'docs/unsorted/' folder
 // relative to the local cwd, and copy them to the remote cwd.
 sftp.putFiles("docs/unsorted/*rfc*.doc");
 
```
Parameters:
local -

Throws:

SftpStatusException

SshException

TransferCancelledException

FileNotFoundException
