      • getMethod

        public static Method getMethod​(java.lang.reflect.Method method)
        Creates a new Method.
        Parameters:
        method - a java.lang.reflect method descriptor
        Returns:
        a Method corresponding to the given Java method declaration.

      • getMethod

        public static Method getMethod​(java.lang.reflect.Constructor<?> constructor)
        Creates a new Method.
        Parameters:

      • getMethod

        public static Method getMethod​(java.lang.String method)
        Returns a Method corresponding to the given Java method declaration.
        Parameters:
        method - a Java method declaration, without argument names, of the form "returnType name (argumentType1, ... argumentTypeN)", where the types are in plain Java (e.g. "int", "float", "java.util.List", ...). Classes of the java.lang package can be specified by their unqualified name; all other classes names must be fully qualified.
        Returns:
        a Method corresponding to the given Java method declaration.
        Throws:
        java.lang.IllegalArgumentException - if method could not get parsed.

        public static Method getMethod​(java.lang.String method,
                               boolean defaultPackage)
        Returns a Method corresponding to the given Java method declaration.
        Parameters:
        method - a Java method declaration, without argument names, of the form "returnType name (argumentType1, ... argumentTypeN)", where the types are in plain Java (e.g. "int", "float", "java.util.List", ...). Classes of the java.lang package may be specified by their unqualified name, depending on the defaultPackage argument; all other classes names must be fully qualified.
        defaultPackage - true if unqualified class names belong to the default package, or false if they correspond to java.lang classes. For instance "Object" means "Object" if this option is true, or "java.lang.Object" otherwise.
        Returns:
        a Method corresponding to the given Java method declaration.
        Throws:
        java.lang.IllegalArgumentException - if method could not get parsed.
