All Implemented Interfaces:

Closeable

public class UUDecoderStream
extends FilterInputStream

This class implements a UUDecoder. It is implemented as a FilterInputStream, so one can just wrap this class around any input stream and read bytes from this filter. The decoding is done as the bytes are read out.

Constructor Detail

UUDecoderStream

public UUDecoderStream(InputStream in)

Create a UUdecoder that decodes the specified input stream. The System property mail.mime.uudecode.ignoreerrors controls whether errors in the encoded data cause an exception or are ignored. The default is false (errors cause exception). The System property mail.mime.uudecode.ignoremissingbeginend controls whether a missing begin or end line cause an exception or are ignored. The default is false (errors cause exception).

Parameters:

in - the input stream

UUDecoderStream

public UUDecoderStream(InputStream in,
                       boolean ignoreErrors,
                       boolean ignoreMissingBeginEnd)

Create a UUdecoder that decodes the specified input stream.

Parameters:

in - the input stream

ignoreErrors - ignore errors?

ignoreMissingBeginEnd - ignore missing begin or end?

Method Detail

read

public int read()
         throws IOException

Read the next decoded byte from this input stream. The byte is returned as an int in the range 0 to 255. If no byte is available because the end of the stream has been reached, the value -1 is returned. This method blocks until input data is available, the end of the stream is detected, or an exception is thrown.

Overrides:

read in class FilterInputStream

Returns:

next byte of data, or -1 if the end of stream is reached.

Throws:

IOException - if an I/O error occurs.

read

public int read(byte[] buf,
                int off,
                int len)
         throws IOException

Overrides:

read in class FilterInputStream

Throws:

IOException

markSupported

public boolean markSupported()

Overrides:

markSupported in class FilterInputStream

available

public int available()
              throws IOException

Overrides:

available in class FilterInputStream

Throws:

IOException

getName

public String getName()
               throws IOException

Get the "name" field from the prefix. This is meant to be the pathname of the decoded file

Returns:

name of decoded file

Throws:

IOException - if an I/O error occurs.

getMode

public int getMode()
            throws IOException

Get the "mode" field from the prefix. This is the permission mode of the source file.

Returns:

permission mode of source file

Throws:

IOException - if an I/O error occurs.
