URL is designed to provide public APIs for parsing - * and synthesizing Uniform Resource Locators as similar as possible to the - * APIs of java.net.URL, but without the ability to open a - * stream or connection. One of the consequences of this is that you can - * construct URLs for protocols for which a URLStreamHandler is not - * available (such as an "https" URL when JSSE is not installed).

WARNING - This class assumes that the string - * representation of a URL conforms to the spec argument - * as described in RFC 2396 "Uniform Resource Identifiers: Generic Syntax": - *
