[`SwiftCpdLexer`](https://github.com/pmd/pmd/blob/master/pmd-swift/src/main/java/net/sourceforge/pmd/lang/swift/cpd/SwiftCpdLexer.java).
* If you wish to filter specific tokens (e.g. comments to support CPD suppression via "CPD-OFF" and "CPD-ON")
you can create your own implementation of
[`AntlrTokenFilter`](https://github.com/pmd/pmd/blob/master/pmd-core/src/main/java/net/sourceforge/pmd/cpd/impl/AntlrTokenFilter.java).
You'll need to override then the protected method `getTokenFilter(AntlrTokenManager)`
and return your custom filter. See the tokenizer for C# as an exmaple:
[`CsTokenizer`](https://github.com/pmd/pmd/blob/master/pmd-cs/src/main/java/net/sourceforge/pmd/lang/cs/cpd/CsTokenizer.java).
and return your custom filter. See the CpdLexer for C# as an exmaple:
[`CsCpdLexer`](https://github.com/pmd/pmd/blob/master/pmd-cs/src/main/java/net/sourceforge/pmd/lang/cs/cpd/CsCpdLexer.java).
If you don't need a custom token filter, you don't need to override the method. It returns the default
`AntlrTokenFilter` which doesn't filter anything.
