## Class DefaultOnlineResource

- Object
- - AbstractMetadata
  - - ModifiableMetadata
    - - ISOMetadata
      - - DefaultOnlineResource

- All Implemented Interfaces:
    Serializable, Cloneable, Emptiable, LenientComparable, IdentifiedObject, OnlineResource

      public class DefaultOnlineResource
      extends ISOMetadata
      implements OnlineResource

  Information about on-line sources from which the dataset, specification, or community profile name and extended metadata elements can be obtained. The following property is mandatory in a well-formed metadata according ISO 19115:
  `CI_OnlineResource` `└─linkage………………` Location (address) for on-line access using a Uniform Resource Locator address or similar addressing scheme.

  Limitations:

  - Instances of this class are not synchronized for multi-threading. Synchronization, if needed, is caller's responsibility.
  - Serialized objects of this class are not guaranteed to be compatible with future Apache SIS releases. Serialization support is appropriate for short term storage or RMI between applications running the same version of Apache SIS. For long term storage, use `XML` instead.
  Since:
    0.3

- - ### Constructor Detail

    - #### DefaultOnlineResource

          public DefaultOnlineResource()

      Creates an initially empty on line resource.

    - #### DefaultOnlineResource

          public DefaultOnlineResource(URI linkage)

      Creates an on line resource initialized to the given URI.
      Parameters:
        `linkage` - the location for on-line access using a Uniform Resource Locator address, or `null` if none.

    - #### DefaultOnlineResource

          public DefaultOnlineResource(OnlineResource object)

      Constructs a new instance initialized with the values from the specified metadata object. This is a shallow copy constructor, since the other metadata contained in the given object are not recursively copied.
      Parameters:
        `object` - the metadata to copy values from, or `null` if none.
      See Also:
        `castOrCopy(OnlineResource)`

  - ### Method Detail

    - #### castOrCopy

          public static DefaultOnlineResource castOrCopy(OnlineResource object)

      Returns a SIS metadata implementation with the values of the given arbitrary implementation. This method performs the first applicable action in the following choices:
      - If the given object is `null`, then this method returns `null`.
      - Otherwise if the given object is already an instance of `DefaultOnlineResource`, then it is returned unchanged.
      - Otherwise a new `DefaultOnlineResource` instance is created using the copy constructor and returned. Note that this is a shallow copy operation, since the other metadata contained in the given object are not recursively copied.
      Parameters:
        `object` - the object to get as a SIS implementation, or `null` if none.
      Returns:
        a SIS implementation containing the values of the given object (may be the given object itself), or `null` if the argument was null.

    - #### getApplicationProfile

          public String getApplicationProfile()

      Returns the name of an application profile that can be used with the online resource. Returns `null` if none.
      Specified by:
        `getApplicationProfile` in interface `OnlineResource`
      Returns:
        application profile that can be used with the online resource, or `null`.

    - #### setApplicationProfile

          public void setApplicationProfile(String newValue)

      Sets the name of an application profile that can be used with the online resource.
      Parameters:
        `newValue` - the new application profile.

    - #### getName
