public static byte[] read(java.net.URL input)
throws java.io.IOException
input - the URL to read
java.io.IOException - in case of I/O error
public static byte[] read(java.io.InputStream source)
throws java.io.IOException
input - the InputStream to read
java.io.IOException - in case of I/O error
public static void copy(java.io.OutputStream dest,
java.io.InputStream source,
int bufSize)
throws java.io.IOException
InputStream to an OutputStream until an
end-of-stream is reached on the source InputStream. This method
does not attempt to close either the source or the destination
stream.
dest - destination OutputStreamsource - source InputStreambufSize - write buffer size
java.io.IOException - in case of I/O error
public static void copy(java.io.Writer dest,
java.io.Reader source,
int bufSize)
throws java.io.IOException
Reader to an Writer until an
end-of-stream is reached on the source Reader. This method does
not attempt to close either the source or the destination
stream.
dest - destination Writersource - source ReaderbufSize - write buffer size
java.io.IOException - in case of I/O error
public static void copy(java.io.OutputStream dest,
java.io.InputStream source)
throws java.io.IOException

throws java.io.IOException
URL stream.
dest - destination OutputStreamsource - source URL
java.io.IOExceptioncopy(java.io.OutputStream, java.io.InputStream, int)
public static void write(java.io.OutputStream dest,
java.io.Serializable src)
throws java.io.IOException
Serializable object to an output stream using the
ObjectOutputStream mechanism.
