| AbstractStringBuilder | java.lang |
This package-private class is the abstract
superclass of StringBuffer and
StringBuilder. Because this class is not public,
you may not use it directly. It is included in this quick-reference
to fully document the shared API of its two subclasses.Note that many of the methods of this class are declared to return an
AbstractStringBuilder object.
StringBuilder and StringBuffer(
) override those methods and narrow the return type to
StringBuilder or StringBuffer.
(This is an example of
"covariant returns,"
which are allowed in Java 5.0 and later.)
