Enum ResourceType

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<ResourceType>

    public enum ResourceType
    extends java.lang.Enum<ResourceType>
    Defines different kinds of resources that can be at the end of a URL. This is used for the purposes of deciding what actions to invoke on it, for instance in the context of DataLink.

      • values

        public static ResourceType[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
        for (ResourceType c : ResourceType.values())
            System.out.println(c);
        
        Returns:
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static ResourceType valueOf​(java.lang.String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null
      • guessResourceType

        public static ResourceType guessResourceType​(java.net.URL url,
                                                     java.lang.String contentType,
                                                     java.lang.String standardId)
        Attempts to determine the type of resource characterised by available information. Works on a best-efforts basis.
        Parameters:
        url - resource URL
        contentType - known or inferred Content-Type string (RFC 2045), or null if not known
        standardId - known or inferred IVOA standard ID, or null if not known
        Returns:
        best guess at the type of resource corresponding to the given information
