Class ClassArgParser

  • public class ClassArgParser
extends java.lang.Object
    Parser used to resolve arguments into java classes. Interprets command-line args as either class names, .class files or resources, .java files or resources, or metadata files or resources conforming to the common format defined by CFMetaDataParser. Transforms the information in these args into Class instances. Note that when parsing .java files, only the main class in the file is detected. Other classes defined in the file, such as inner classes, are not added to the returned classes list.
