Java io bufferedoutputstream write

Java io bufferedoutputstream write

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.

Field Summary

Fields declared in class java.io.FilterOutputStream

Constructor Summary

Creates a new buffered output stream to write data to the specified underlying output stream with the specified buffer size.

Method Summary

Writes len bytes from the specified byte array starting at offset off to this buffered output stream.

Methods declared in class java.io.FilterOutputStream

Methods declared in class java.io.OutputStream

Methods declared in class java.lang.Object

Field Detail

buf

count

The number of valid bytes in the buffer. This value is always in the range 0 through buf.length ; elements buf[0] through buf[count-1] contain valid byte data.

Constructor Detail

BufferedOutputStream

BufferedOutputStream

Creates a new buffered output stream to write data to the specified underlying output stream with the specified buffer size.

Method Detail

write

write

Writes len bytes from the specified byte array starting at offset off to this buffered output stream. Ordinarily this method stores bytes from the given array into this stream’s buffer, flushing the buffer to the underlying output stream as needed. If the requested length is at least as large as this stream’s buffer, however, then this method will flush the buffer and write the bytes directly to the underlying output stream. Thus redundant BufferedOutputStream s will not copy data unnecessarily.

flush

Flushes this buffered output stream. This forces any buffered output bytes to be written out to the underlying output stream.
