DataTransferHelper

public DataTransferHelper(InputStream in,
                          OutputStream out,
                          boolean isBinaryTransfer)

Creates a DataTransferHelper

Parameters:

isBinaryTransfer - boolean to transfer in binary or ascii

Method Detail

reset

public void reset(InputStream in,
                  OutputStream out,
                  boolean isBinaryTransfer)

transfer

public int transfer()
             throws IOException

Transfers the content from InputStream to OutputStream

Throws:

IOException

transferData

protected int transferData(InputStream in,
                           OutputStream out,
                           boolean isBinaryTransfer)
                    throws IOException

Transfers content from inputstream to outputstream

Parameters:

in - the input stream

out - the output stream

isBinaryTransfer - if true binary transfer, if false ascii transfer with bytes put on wire according to ftp rfc (no

Returns:

int the number of bytes transfered

Throws:

IOException

transferBinaryData

protected final int transferBinaryData(InputStream in,
                                       OutputStream out)
                                throws IOException

Transfer content from an inputstream to an outputstream, with no newline processing

Returns:

int the number of bytes transfered

Throws:

IOException

transferAsciiData

protected final int transferAsciiData(InputStream in,
                                      OutputStream out)
                               throws IOException

Transfer content from an inputstream to an outputstream, processing newlines. Warning this method does not work for 2 byte characters.

Returns:

int the number of bytes transfered

Throws:

IOException

getDesiredBufferSize

protected int getDesiredBufferSize()

determines the size of the byte buffer

getByteBuffer

protected byte[] getByteBuffer()

gets a bytes buffer
