lock - java.lang.Object

Method Detail

basicClose

public void basicClose()
                throws java.io.IOException

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

Throws:

java.io.IOException - If an I/O error occurs

close

public void close()
           throws java.io.IOException

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

Specified by:

close in interface java.io.Closeable

Specified by:

close in class java.io.Writer

Throws:

java.io.IOException - If an I/O error occurs

flush

public void flush()
           throws java.io.IOException

Flush 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.

Specified by:

flush in interface java.io.Flushable

Specified by:

flush in class java.io.Writer

Throws:

java.io.IOException - If an I/O error occurs

write

public void write(char[] cbuf,
                  int off,
                  int len)
           throws java.io.IOException

Write a portion of an array of characters.

Specified by:

write in class java.io.Writer

Parameters:

cbuf - Array of characters

off - Offset from which to start writing characters

len - Number of characters to write

Throws:

java.io.IOException - If an I/O error occurs
