Constructor Detail

StringBufferWriter

public StringBufferWriter(java.lang.StringBuffer buffer)
Method Detail

getBuffer

public java.lang.StringBuffer getBuffer()

write

public void write(int c)
           throws java.io.IOException
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.

Overrides:
write in class java.io.Writer
Parameters:
c - int specifying a character to be written.
Throws:
java.io.IOException - If an I/O error occurs

write

public void write(java.lang.String str)
           throws java.io.IOException
Write a string.

Overrides:
write in class java.io.Writer
Parameters:
str - String to be written
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

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.

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.

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

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
