                                  E analysisObject)
        Eagerly put a method analysis object in the cache. This can be necessary if an method analysis engine invokes other analysis engines that might recursively require the analysis being produced.
        Type Parameters:
        E - the type of the analysis (e.g., FoobarAnalysis)
        Parameters:
        analysisClass - the analysis class object (e.g., FoobarAnalysis.class)

      • purgeMethodAnalyses

        void purgeMethodAnalyses​(@Nonnull
                         MethodDescriptor methodDescriptor)
        Purge all analysis results for given method. This can be called when a CFG is pruned and we want to compute more accurate analysis results on the new CFG.
        Parameters:
        methodDescriptor - method whose analysis results should be purged

      • purgeAllMethodAnalysis

        void purgeAllMethodAnalysis()
        Purge all method analysis results for all methods.

      • purgeClassAnalysis

        void purgeClassAnalysis​(java.lang.Class<?> analysisClass)
        Purge all class analysis results of a particular kind

      • registerDatabaseFactory

        <E> void registerDatabaseFactory​(java.lang.Class<E> databaseClass,
                                 IDatabaseFactory<E> databaseFactory)
        Register a database factory.
        Type Parameters:
        E - type of database
        Parameters:
        databaseClass - Class of database
        databaseFactory - the database factory

      • getDatabase

        <E> E getDatabase​(java.lang.Class<E> databaseClass)
        Get a database. Note: an unchecked analysis exception will be thrown if the database cannot be instantiated. Since instantiation of most kinds of databases simply involves creating an object (and not opening a file or other failure-prone operation), throwing a CheckedAnalysisException creates too great of an exception-handling burden on analyses and detectors which use databases.
        Type Parameters:
        E - type of database
        Parameters:
        databaseClass - Class of database
        Returns:
        the database (which is created by a database factory if required)

      • getOptionalDatabase

        @CheckForNull
<E> E getOptionalDatabase​(java.lang.Class<E> databaseClass)

      • eagerlyPutDatabase

        <E> void eagerlyPutDatabase​(java.lang.Class<E> databaseClass,
                            E database)
        Eagerly install a database. This avoids the need to register a database factory.
        Type Parameters:
        E - type of database
        Parameters:
        databaseClass - Class of database
        database - database object

        Get the error logger.
        Returns:
        the error logger
