Examples of java.io.BufferedOutputStream

java.io.BufferedOutputStream
The class implements a buffered output stream. By setting up such an output stream, an application can write bytes to the underlying output stream without necessarily causing a call to the underlying system for each byte written. @author Arthur van Hoff @version 1.34, 11/17/05 @since JDK1.0
