Method Detail

close

public static void close(java.io.Closeable closeable)

Closes silently the closable object. If it is FLushable, it will be flushed first. No exception will be thrown if an I/O error occurs.

copy

public static int copy(java.io.InputStream input,
       java.io.OutputStream output)
                throws java.io.IOException

Copies input stream to output stream using buffer. Streams don't have to be wrapped to buffered, since copying is already optimized.

Throws:

java.io.IOException

copy

public static int copy(java.io.InputStream input,
       java.io.OutputStream output,
       int byteCount)
                throws java.io.IOException

Copies specified number of bytes from input stream to output stream using buffer.

Throws:

java.io.IOException

copy

public static void copy(java.io.InputStream input,
        java.io.Writer output)
                 throws java.io.IOException

Copies input stream to writer using buffer.

Throws:

java.io.IOException

copy

Copies specified number of bytes from input stream to writer using buffer.

Throws:
