SimilaritySearchService

The similarity search service finds classes and methods in the workspace that are similar to a given reference, based on fingerprinting of their structure. This is useful for finding the same logic across multiple resources (for example, the same class in different versions of an application, or similar decryption functions from an obfuscator).

The service allows you to:

• Search for methods similar to a reference method
• Search for classes similar to a reference class

Searching for similar methods

List<SimilarMethodSearchResult> results = similaritySearchService.searchMethods(referenceMethodPath, similarMethodSearchOptions);
for (SimilarMethodSearchResult result : results)
    logger.info("Similar method: {} ({}%)", result.path(), result.similarity());

Searching for similar classes

List<SimilarClassSearchResult> results = similaritySearchService.searchClasses(referenceClassPath, similarClassSearchOptions);
for (SimilarClassSearchResult result : results)
    logger.info("Similar class: {} ({}%)", result.path(), result.similarity());
