All Implemented Interfaces:
Serializable
public class JaxmURI extends Object implements Serializable
A class to represent a Uniform Resource Identifier (URI). This class is designed to handle the parsing of URIs and provide access to the various components (scheme, host, port, userinfo, path, query string and fragment) that may constitute a URI.

Parsing of a URI specification is done according to the URI syntax described in RFC 2396. Every URI consists of a scheme, followed by a colon (':'), followed by a scheme-specific part. For URIs that follow the "generic URI" syntax, the scheme- specific part begins with two slashes ("//") and may be followed by an authority segment (comprised of user information, host, and port), path segment, query segment and fragment. Note that RFC 2396 no longer specifies the use of the parameters segment and excludes the "user:password" syntax as part of the authority segment. If "user:password" appears in a URI, the entire user/password string is stored as userinfo.

For URIs that do not follow the "generic URI" syntax (e.g. mailto), the entire scheme-specific part is treated as the "path" portion of the URI.

Note that, unlike the java.net.URL class, this class does not provide any built-in network access functionality nor does it provide any scheme-specific functionality (for example, it does not know a default port for a specific scheme). Rather, it only knows the grammar and basic set of operations that can be applied to a URI.

  • Constructor Details

    • JaxmURI

      public JaxmURI()
      Construct a new and uninitialized URI.

    • JaxmURI

      public JaxmURI(JaxmURI p_other)

    • JaxmURI

      public JaxmURI(String p_uriSpec) throws JaxmURI.MalformedURIException
      Construct a new URI from a URI specification string. If the specification follows the "generic URI" syntax, (two slashes following the first colon), the specification will be parsed accordingly - setting the scheme, userinfo, host,port, path, query string and fragment fields as necessary. If the specification does not follow the "generic URI" syntax, the specification is parsed into a scheme and scheme-specific part (stored as the path) only.
      Parameters:
      p_uriSpec - the URI specification string (cannot be null or empty)
      Throws:
      JaxmURI.MalformedURIException - if p_uriSpec violates any syntax rules

If the supplied path includes a query string and/or fragment, these fields will be parsed and set as well. Note that, for URIs following the "generic URI" syntax, the path specified should start with a slash. For URIs that do not follow the generic URI syntax, this method sets the scheme-specific part.

If the current path does not end in a slash and the path to be appended does not begin with a slash, a slash will be appended to the current path before the new segment is added. Also, if the current path ends in a slash and the new segment begins with a slash, the extra slash will be removed before the new segment is appended.
      Parameters:
      p_addToPath - the new segment to be added to the current path

      Parameters:
      p_scheme - scheme name
      Returns:
      true if the scheme is conformant, false otherwise

    • isWellFormedAddress

      public static boolean isWellFormedAddress(String p_address)
      Determine whether a string is syntactically capable of representing a valid IPv4 address or the domain name of a network host. A valid IPv4 address consists of four decimal digit groups separated by a '.'. A hostname consists of domain labels (each of which must begin and end with an alphanumeric but may contain '-') separated by a '.'. See RFC 2396 Section 3.2.2.
      Parameters:
