close back to summary

close	back to summary
public void close() Implements abstract java.io.Writer.close. Implements java.io.Closeable.close. Doc from java.io.Writer.close. Closes the stream, flushing it first. Once the stream has been closed, further write() or flush() invocations will cause an IOException to be thrown. Closing a previously closed stream has no effect. See Also `java.io.Writer#close()`

public void close()

Implements abstract java.io.Writer.close.

Implements java.io.Closeable.close.

Doc from java.io.Writer.close.

Closes the stream, flushing it first. Once the stream has been closed, further write() or flush() invocations will cause an IOException to be thrown. Closing a previously closed stream has no effect.

flush back to summary

flush	back to summary
public void flush() Implements abstract java.io.Writer.flush. Implements java.io.Flushable.flush. Doc from java.io.Writer.flush. Flushes the stream. If the stream has saved any characters from the various write() methods in a buffer, write them immediately to their intended destination. Then, if that destination is another character or byte stream, flush it. Thus one flush() invocation will flush all the buffers in a chain of Writers and OutputStreams. 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. See Also `java.io.Writer#flush()`

write	back to summary
public void write(int idx) Overrides java.io.Writer.write. Doc from java.io.Writer.write. Writes a single character. The character to be written is contained in the 16 low-order bits of the given integer value; the 16 high-order bits are ignored.
