Class SftpDirEntryIterator

java.lang.Object

org.apache.sshd.common.util.logging.AbstractLoggingBean

org.apache.sshd.client.subsystem.sftp.SftpDirEntryIterator

All Implemented Interfaces:

Closeable, AutoCloseable, Channel, Iterator<SftpClient.DirEntry>

public class SftpDirEntryIterator
extends AbstractLoggingBean
implements Iterator<SftpClient.DirEntry>, Channel

Iterates over the available directory entries for a given path. Note: if the iteration is carried out until no more entries are available, then no need to close the iterator. Otherwise, it is recommended to close it so as to release the internal handle.

Constructor Detail

SftpDirEntryIterator

public SftpDirEntryIterator(SftpClient client,
                            String path)
                     throws IOException

Parameters:

client - The SftpClient instance to use for the iteration

path - The remote directory path

Throws:

IOException - If failed to gain access to the remote directory path

SftpDirEntryIterator

public SftpDirEntryIterator(SftpClient client,
                            SftpClient.Handle dirHandle)

Parameters:

client - The SftpClient instance to use for the iteration

dirHandle - The directory SftpClient.Handle to use for listing the entries

SftpDirEntryIterator

public SftpDirEntryIterator(SftpClient client,
                            String path,
                            SftpClient.Handle dirHandle,
                            boolean closeOnFinished)

Parameters:

client - The SftpClient instance to use for the iteration

path - A hint as to the remote directory path - used only for logging

dirHandle - The directory SftpClient.Handle to use for listing the entries

closeOnFinished - If true then close the directory handle when all entries have been exhausted

Method Detail
