[edit] public OutputStream()

Default constructor.

[edit] Public Methods

[edit] public void close()

Close this OutputStream. Concrete implementations of this class should free any resources during close. This implementation does nothing.

Throws

IOException	If an error occurs attempting to close this OutputStream.

[edit] public void flush()

Flush this OutputStream. Concrete implementations of this class should ensure any pending writes to the underlying stream are written out when this method is envoked. This implementation does nothing.

Throws

IOException	If an error occurs attempting to flush this OutputStream.

[edit] public void write(byte[] buffer)

Writes the entire contents of the byte array buffer to this OutputStream.

Parameters

buffer	the buffer to be written

Throws

IOException	If an error occurs attempting to write to this OutputStream.

[edit] public abstract void write(int oneByte)

Writes the specified byte oneByte to this OutputStream. Only the low order byte of oneByte is written.

Parameters

oneByte	the byte to be written

Throws

IOException	If an error occurs attempting to write to this OutputStream.

[edit] public void write(byte[] buffer, int offset, int count)

Writes count bytes from the byte array buffer starting at offset to this OutputStream.

Parameters

buffer	the buffer to be written
offset	offset in buffer to get bytes
count	number of bytes in buffer to write

Throws

IOException	If an error occurs attempting to write to this OutputStream.
IndexOutOfBoundsException	If offset or count are outside of bounds.
