    • Method Detail

      • createTypeRef

        private Descriptors.TypeRef createTypeRef​(java.lang.String binaryClassName)

      • getClassSignature

        public ClassSignature getClassSignature​(java.lang.String signature)

      • getMethodSignature

        public MethodSignature getMethodSignature​(java.lang.String signature)

      • getFieldSignature

        public FieldSignature getFieldSignature​(java.lang.String signature)

      • getShortName

        public static java.lang.String getShortName​(java.lang.String fqn)
        Return the short name of a FQN

      • binaryToFQN

        public static java.lang.String binaryToFQN​(java.lang.String binary)

      • binaryClassToFQN

        public static java.lang.String binaryClassToFQN​(java.lang.String path)

      • fqnToBinary

        public static java.lang.String fqnToBinary​(java.lang.String fqn)

      • fqnClassToBinary

        public static java.lang.String fqnClassToBinary​(java.lang.String fqn)
        Converts the given fully-qualified top-level class name into the binary class path. For example:

        my.pkg.And.Clazz becomes:

        my/pkg/And$Clazz.class

        This method uses determine(String) to split the class and package names, which is imperfect.

        Parameters:
        fqn - the fully-qualified name to be converted.
        Returns:
        The binary name corresponding to the fully-qualified name.

      • classToPath

        public static java.lang.String classToPath​(java.lang.String className)
        Converts the class name (without the package qualifier) into the corresponding binary name. For example:

        my.pkg.and.Clazz becomes:

        my$pkg$and$Clazz.class As you can see, this method is not smart about distinguishing between package and class nesting - it always converts the . into a $.

        Parameters:
        className - the name of the class to be converted.
        Returns:
        The binary name corresponding to the class name.

      • getPackage

        public static java.lang.String getPackage​(java.lang.String binaryNameOrFqn)

      • fqnToPath

        public static java.lang.String fqnToPath​(java.lang.String s)

      • getTypeRefFromPath

        public Descriptors.TypeRef getTypeRefFromPath​(java.lang.String path)

      • pathToFqn

        public static java.lang.String pathToFqn​(java.lang.String path)

      • isBinaryClass

        public static boolean isBinaryClass​(java.lang.String resource)

      • binaryToSimple

        public static java.lang.String binaryToSimple​(java.lang.String resource)
        Java really screwed up in using different names for the binary path and the fqns. This calculates the simple name of a potentially nested class.
        Parameters:
        resource - ( segment '/')+ (name '$')* name '.class'
        Returns:
        the last name

      • isClassName

        public static boolean isClassName​(java.lang.String fqn)
        Heuristic for a class name. We assume a segment with
        Parameters:
        fqn - can be a class name, nested class, or simple name
        Returns:
        true if the last segment starts with an upper case

      • determine

        public static Result<java.lang.String[],​java.lang.String> determine​(java.lang.String fqn)
        Return a 2 element array based on the fqn. The first element is the package name, the second is the class name. Each can be absent, but not both. The class name can be a nested class (will contain a '.' then)

        Because there is an inherent ambiguity between packages and nested classes, this method uses a heuristic that works most of the time: the start of the class name is considered to be the first element that begins with a capital letter. Hence "simple.Sample.Sumple" => ["simple", "Sample.Sumple" ] and not [ "simple.Sample", "Sumple" ].

        Parameters:
        fqn - a Java identifier name, either a simple class name, a qualified class name, or a package name
        Returns:
        a Result with 2 element array with [package, class]
