5.4.15. The MutableBuffer Class

The MutableBuffer class is a buffer on which certain string operations such as concatenation can be performed very efficiently. Unlike String objects, MutableBuffers can be altered without requiring a new object allocation. A MutableBuffer object can provide better performance for algorithms that involve frequent concatenations to build up longer string objects because it creates fewer intermediate objects.

Note

The MutableBuffer class also has available class methods that its metaclass, the Class class (Section 5.1.2, “The Class Class”), defines.
