public final class StringContent extends Object implements AbstractDocument.Content, Serializable
It is generally recommended that the gap buffer or piece table implementations be used instead. This buffer does not scale up to large sizes.
Warning:
Serialized objects of this class will not be compatible with
future Swing releases. The current serialization support is
appropriate for short term storage or RMI between applications running
the same version of Swing. As of 1.4, support for long term storage
of all JavaBeans™
has been added to the java.beans package.
Please see XMLEncoder.

If v is not null the matching Positions are placed in
there. The vector with the resulting Positions are returned.
