JavaParserTypeSolver

public JavaParserTypeSolver(Path srcDir,
 ParserConfiguration parserConfiguration,
 long cacheSizeLimit)

Parameters:

srcDir - is the source code directory for the type solver.

parserConfiguration - is the configuration the solver should use when inspecting source code files.

cacheSizeLimit - is an optional size limit to the internal caches used by this solver. Be advised that setting the size too low might lead to noticeable performance degradation. However, using a size limit is advised when solving symbols in large code sources. In such cases, internal caches might consume large amounts of heap space.

JavaParserTypeSolver

public JavaParserTypeSolver(Path srcDir,
 JavaParser javaParser,
 Cache<Path, Optional<CompilationUnit>> parsedFilesCache,
 Cache<Path, List<CompilationUnit>> parsedDirectoriesCache,
 Cache<String, SymbolReference<ResolvedReferenceTypeDeclaration>> foundTypesCache)

Create a JavaParserTypeSolver with a custom cache system.

Parameters:

srcDir - The source code directory for the type solver.

javaParser - The JavaParser to be used when parsing .java files.

parsedFilesCache - The cache to be used to store CompilationUnit that is associated with a file.

parsedDirectoriesCache - The cache to store the list of CompilationUnit in a given directory.

foundTypesCache - The cache that associated a qualified name to its SymbolReference.
