| Java 1.1 | appendable closeable flushable |
This class is a
character output stream that uses
an internal StringBuffer object as the destination
of the characters written to the stream. When you create a
StringWriter, you may optionally specify an
initial size for the StringBuffer, but you do not
specify the StringBuffer itself; it is managed
internally by the StringWriter and grows as
necessary to accommodate the characters written to it.
StringWriter defines the standard write(
)
,
flush( ), and close( ) methods
all Writer subclasses define, as well as two
methods to obtain the characters that have been written to the
stream's internal buffer. toString(
)
returns the contents of the internal buffer as a
String, and getBuffer(
) returns the buffer itself. Note
that getBuffer( ) returns a reference to the
actual internal buffer, not a copy of it, so any changes you make to
the buffer are reflected in subsequent calls to toString(
). StringWriter is quite similar to
CharArrayWriter, but does not have a byte-stream
analog.
