class StringView: | |
""" | |
StringView implementation using minimal copying with maximum use of | |
reference semantics. Creating a sub-view of an existing StringView using | |
either object slicing or constructing one from another will reüse the same | |
source string object, using a reference rather than a copy. | |
The contents() method can similarly be used to get an iterator (Generator) | |
to access the view contents sequentially without putting it all in memory | |
at once. | |
A brand new string object is only created if the StringView is cast to str. |
