Creates a new instance with the given underlying byte sink.
Closes this output stream and releases any system resources associated with this stream.
Flushes this output stream and forces any buffered output bytes to be written out.
Returns a string representation of the object.
Writes the specified byte to this output stream.
Writes the bytes contained in the argument byte array to the byte sink.
closeis that it closes the output stream. A closed stream cannot perform output operations and cannot be reopened.
close method of
OutputStream does nothing.
flushis that calling it is an indication that, if any bytes previously written have been buffered by the implementation of the output stream, such bytes should immediately be written to their intended destination.
If the intended destination of this stream is an abstraction provided by the underlying operating system, for example a file, then flushing the stream guarantees only that bytes previously written to the stream are passed to the operating system for writing; it does not guarantee that they are actually written to a physical device such as a disk drive.
flush method of
OutputStream does nothing.
toStringmethod returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.
toString method for class
Object returns a string consisting of the name of the class of
which the object is an instance, the at-sign character `
@', and the unsigned hexadecimal representation
of the hash code of the object. In other words, this method returns a string equal to the value of:
getClass().getName() + '@' + Integer.toHexString(hashCode())
writeis that one byte is written to the output stream. The byte to be written is the eight low-order bits of the argument
b. The 24 high-order bits of
OutputStream must provide an
implementation for this method.
IOExceptionmay be thrown if the output stream has been closed.
lenbytes from the specified byte array starting at offset
offto this output stream. The general contract for
write(b, off, len)is that some of the bytes in the array
bare written to the output stream in order; element
b[off]is the first byte written and
b[off+len-1]is the last byte written by this operation.
write method of
the write method of one argument on each of the bytes to be
written out. Subclasses are encouraged to override this method and
provide a more efficient implementation.
NullPointerException is thrown.
off is negative, or
len is negative, or
off+len is greater than the length of the array
b, then an IndexOutOfBoundsException is thrown.
IOExceptionis thrown if the output stream is closed.
