Class GenericUrl

All Implemented Interfaces:
Cloneable, Map<String,Object>

public class GenericUrl extends GenericData
URL builder in which the query parameters are specified as generic data key/value pairs, based on the specification RFC 3986: Uniform Resource Identifier (URI).

The query parameters are specified with the data key name as the parameter name, and the data value as the parameter value. Subclasses can declare fields for known query parameters using the Key annotation. null parameter names are not allowed, but null query values are allowed.

Query parameter values are parsed using UrlEncodedParser.parse(String, Object).

Implementation is not thread-safe.

    • scheme

      private String scheme
      Scheme (lowercase), for example "https".
    • host

      private String host
      Host, for example "www.google.com".

    • port

      private int port
      Port number or -1 if undefined, for example 443.
    • pathParts

      private List<String> pathParts
      Decoded path component by parts with each part separated by a '/' or null for none, for example "/m8/feeds/contacts/default/full" is represented by "", "m8", "feeds", "contacts", "default", "full".

      Use appendRawPath(String) to append to the path, which ensures that no extra slash is added.

      Fragment component or null for none.
    • verbatim

      private boolean verbatim

  • Constructor Details

    • GenericUrl

      public GenericUrl()
    • GenericUrl

      public GenericUrl(String encodedUrl)
      Constructs a GenericUrl from a URL encoded string.

      Any known query parameters with pre-defined fields as data keys will be parsed based on their data type. Any unrecognized query parameter will always be parsed as a string.

      Any MalformedURLException is wrapped in an IllegalArgumentException.

      Upgrade warning: starting in version 1.18 this parses the encodedUrl using new URL(encodedUrl). In previous versions it used new URI(encodedUrl). In particular, this means that only a limited set of schemes are allowed such as "http" and "https", but that parsing is compliant with, at least, RFC 3986.

      Parameters:
      encodedUrl - encoded URL, including any existing query parameters that should be parsed
      Throws:
      IllegalArgumentException - if the URL has a syntax error

      Description copied from class: GenericData
