Constructor Detail

StringBufferWriter

public StringBufferWriter(StringBuffer buffer)

Method Detail

close

public void close()
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: IOException If an I/O error occurs

flush

public void flush()
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.

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.

Throws: IOException If an I/O error occurs

getBuffer

public StringBuffer getBuffer()

write

public void write(int c)
Write 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.

Parameters: c int specifying a character to be written.

Throws: IOException If an I/O error occurs

write

public void write(String str)
Write a string.

Parameters: str String to be written

Throws: IOException If an I/O error occurs

write

public void write(char[] cbuf, int off, int len)
Write a portion of an array of characters.

Parameters: cbuf Array of characters off Offset from which to start writing characters len Number of characters to write

Throws: IOException If an I/O error occurs
