Classes:

• CopyStreamListener: The CopyStreamListener class can accept CopyStreamEvents to keep track of the progress of a stream copying operation. However, it is currently not used that way within NetComponents for performance reasons. Rather the bytesTransferred(long, int) method is called directly rather than passing an event to bytesTransferred(CopyStreamEvent), saving the creation of a CopyStreamEvent instance. Also, the only place where CopyStreamListener is currently used within NetComponents is in the static methods of the uninstantiable org.apache.commons.io.Util class, which would preclude the use of addCopyStreamListener ...
• FromNetASCIIOutputStream: This class wraps an output stream, replacing all occurrences of <CR><LF> (carriage return followed by a linefeed), which is the NETASCII standard for representing a newline, with the local line separator representation. You would use this class to implement ASCII file transfers requiring conversion from NETASCII. Because of the translation process, a call to flush() will not flush the last byte written if that byte was a carriage return. A call to close() 55 , however, will flush the carriage return.
• DotTerminatedMessageReader: DotTerminatedMessageReader is a class used to read messages from a server that are terminated by a single dot followed by a <CR><LF> sequence and with double dots appearing at the begining of lines which do not signal end of message yet start with a dot. Various Internet protocols such as NNTP and POP3 produce messages of this type. This class handles stripping of the duplicate period at the beginning of lines starting with a period, converts NETASCII newlines to the local line separator format, truncates the end of message indicator, and ensures you cannot read past the end of the ...
• DotTerminatedMessageWriter: DotTerminatedMessageWriter is a class used to write messages to a server that are terminated by a single dot followed by a <CR><LF> sequence and with double dots appearing at the begining of lines which do not signal end of message yet start with a dot. Various Internet protocols such as NNTP and POP3 produce messages of this type. This class handles the doubling of line-starting periods, converts single linefeeds to NETASCII newlines, and on closing will send the final message terminator dot and NETASCII newline sequence.
• CopyStreamAdapter: The CopyStreamAdapter will relay CopyStreamEvents to a list of listeners when either of its bytesTransferred() methods are called. Its purpose is to facilitate the notification of the progress of a copy operation performed by one of the static copyStream() methods in org.apache.commons.io.Util to multiple listeners. The static copyStream() methods invoke the bytesTransfered(long, int) of a CopyStreamListener for performance reasons and also because multiple listeners cannot be registered given that the methods are static.
• SocketOutputStream: This class wraps an output stream, storing a reference to its originating socket. When the stream is closed, it will also close the socket immediately afterward. This class is useful for situations where you are dealing with a stream originating from a socket, but do not have a reference to the socket, and want to make sure it closes when the stream closes.
• SocketInputStream: This class wraps an input stream, storing a reference to its originating socket. When the stream is closed, it will also close the socket immediately afterward. This class is useful for situations where you are dealing with a stream originating from a socket, but do not have a reference to the socket, and want to make sure it closes when the stream closes.
• FromNetASCIIInputStream: This class wraps an input stream, replacing all occurrences of <CR><LF> (carriage return followed by a linefeed), which is the NETASCII standard for representing a newline, with the local line separator representation. You would use this class to implement ASCII file transfers requiring conversion from NETASCII.
• ToNetASCIIOutputStream: This class wraps an output stream, replacing all singly occurring <LF> (linefeed) characters with <CR><LF> (carriage return followed by linefeed), which is the NETASCII standard for representing a newline. You would use this class to implement ASCII file transfers requiring conversion to NETASCII.
• ToNetASCIIInputStream: This class wraps an input stream, replacing all singly occurring <LF> (linefeed) characters with <CR><LF> (carriage return followed by linefeed), which is the NETASCII standard for representing a newline. You would use this class to implement ASCII file transfers requiring conversion to NETASCII.
• CopyStreamEvent: A CopyStreamEvent is triggered after every write performed by a stream copying operation. The event stores the number of bytes transferred by the write triggering the event as well as the total number of bytes transferred so far by the copy operation.
• CopyStreamException: The CopyStreamException class is thrown by the org.apache.commons.io.Util copyStream() methods. It stores the number of bytes confirmed to have been transferred before an I/O error as well as the IOException responsible for the failure of a copy operation.
• Util: The Util class cannot be instantiated and stores short static convenience methods that are often quite useful.
