Affects Version/s: None
Fix Version/s: 2.1
The Token class should be more friendly to classes not in it's package:
1) add setTermText()
2) remove final from class and toString()
3) add clone()
Support for (1):
TokenFilters in the same package as Token are able to do things like
"t.termText = t.termText.toLowerCase();" which is more efficient, but more importantly less error prone. Without the ability to change only the term text, a new Token must be created, and one must remember to set all the properties correctly. This exact issue caused this bug:
Support for (2):
Removing final allows one to subclass Token. I didn't see any performance impact after removing final.
I can go into more detail on why I want to subclass Token if anyone is interested.
Support for (3):
- support for a synonym TokenFilter, where one needs to make two tokens from one (same args that support (1), and esp important if instance is a subclass of Token).
