com.aptana.shared_core.string.FastStringBuffer
This is a custom string buffer optimized for append(), clear() and deleteLast(). Basically it aims at being created once, being used for something, having clear() called and then reused (ultimately providing minimum allocation/garbage collection overhead for that use-case). append() is optimizing by doing less checks (so, exceptions thrown may be uglier on invalid operations and null is not checked for in the common case -- use appendObject if it may be null). clear() and deleteLast() only change the internal count and have almost zero overhead. Note that it's also not synchronized. @author Fabio
