When filtering tokens, the analyzeToken method can be overriden to access the current token. This can then be used to implement isLanguageSpecificDiscarding. However, it may be desirable to "look ahead" and base the decision of whether to filter or not on multiple tokens. In order to support this new use case, a new extension point analyzeTokens is provided, which not only has access to the current token, but can also iterate over the upcoming tokens. The functionality of iterating over remaining tokens uses Guava for its implementation. Since pmd-core targets Java 7, the Android flavour of Guava is used. In order to stay consistent with pmd-apex-jorje, this has also been adjusted to the Android flavour. For PMD 7.0, the jre flavour can be used instead.
