Class ClassNodeResolver

    • Field Detail

      • NO_CLASS

        protected static final ClassNode NO_CLASS
        Internal helper used to indicate a cache hit for a class that does not exist. This way further lookups through a slow findClassNode(String, CompilationUnit) path can be avoided. WARNING: This class is not to be used outside of ClassNodeResolver.

      • resolveName

        public ClassNodeResolver.LookupResult resolveName​(String name,
                                                          CompilationUnit compilationUnit)
        Resolves the name of a class to a SourceUnit or ClassNode. If no class or source is found this method returns null. A lookup is done by first asking the cache if there is an entry for the class already available to then call findClassNode(String, CompilationUnit). The result of that method call will be cached if a ClassNode is found. If a SourceUnit is found, this method will not be asked later on again for that class, because ResolveVisitor will first ask the CompilationUnit for classes in the compilation queue and it will find the class for that SourceUnit there then. method return a ClassNode instead of a SourceUnit, the res
        Parameters:
        name - - the name of the class
        compilationUnit - - the current CompilationUnit
        Returns:
        the LookupResult
      • cacheClass

        public void cacheClass​(String name,
                               ClassNode res)
        caches a ClassNode
        Parameters:
        name - - the name of the class
        res - - the ClassNode for that name
      • getFromClassCache

        public ClassNode getFromClassCache​(String name)
        returns whatever is stored in the class cache for the given name
        Parameters:
        name - - the name of the class
        Returns:
        the result of the lookup, which may be null
      • findClassNode

        public ClassNodeResolver.LookupResult findClassNode​(String name,
                                                            CompilationUnit compilationUnit)
        Extension point for custom lookup logic of finding ClassNodes. Per default this will use the CompilationUnit class loader to do a lookup on the class path and load the needed class using that loader. Or if a script is found and that script is seen as "newer", the script will be used instead of the class.
        Parameters:
        name - - the name of the class
        compilationUnit - - the current compilation unit
        Returns:
        the lookup result
