Method Detail

write

public void write(char ch)

Description copied from interface: Writer

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.

Subclasses that intend to support efficient single-character output should override this method.

Specified by:

write in interface Writer

Parameters:

ch - int specifying a character to be written

write

public void write(String str)

Description copied from interface: Writer

Writes a string.

Specified by:

write in interface Writer

Parameters:

str - String to be written

write

public void write(String str,
                  int start,
                  int length)
           throws IOException

Description copied from interface: Writer

Writes a portion of a string.

Specified by:

write in interface Writer

Parameters:

str - A String

start - Offset from which to start writing characters

length - Number of characters to write

Throws:

IOException - If an I/O error occurs

flush

public void flush()

Description copied from interface: Writer

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.

Specified by:

flush in interface Writer

close

public void close()

Description copied from interface: Writer

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.

Specified by:

close in interface Writer

toString

public String toString()

Overrides:

toString in class Object
