# Class DefaultAggregateInformation

Object
AbstractMetadata
ModifiableMetadata
ISOMetadata
DefaultAssociatedResource
DefaultAggregateInformation

All Implemented Interfaces:
  `Serializable`, `Emptiable`, `LenientComparable`, `IdentifiedObject`, `AggregateInformation`

public class DefaultAggregateInformation extends DefaultAssociatedResource implements AggregateInformation
Associated resource information. The following properties are mandatory or conditional (i.e. mandatory under some circumstances) in a well-formed metadata according ISO 19115:
`MD_AggregateInformation` `├─associationType…………` Type of relation between the resources. `├─metadataReference……` Reference to the metadata of the associated resource. `│ ├─title…………………………` Name by which the cited resource is known. `│ └─date……………………………` Reference date for the cited resource. `└─name………………………………………` Citation information about the associated resource.
According ISO 19115, at least one of name and metadata reference shall be provided.
Upcoming API change — renaming
As of ISO 19115:2014, `AggregateInformation` has been renamed `AssociatedResource`. This class will be replaced by `DefaultAssociatedResource` when GeoAPI will provide the `AssociatedResource` interface (tentatively in GeoAPI 3.1 or 4.0).

## 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 Details

  - ### DefaultAggregateInformation

    public DefaultAggregateInformation()
    Constructs an initially empty Aggregate dataset information.

  - ### DefaultAggregateInformation

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

- ## Method Details

  - ### castOrCopy

    public static DefaultAggregateInformation castOrCopy(AggregateInformation 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 `DefaultAggregateInformation`, then it is returned unchanged.
    - Otherwise a new `DefaultAggregateInformation` instance is created using the copy constructor and returned. Note that this is a shallow copy operation, because 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.

  - ### getAggregateDataSetName

    @Deprecated(since="1.0") public Citation getAggregateDataSetName()
    Deprecated.
    As of ISO 19115:2014, replaced by `DefaultAssociatedResource​.getName()`.
    Citation information about the aggregate dataset.
    Specified by:
      `getAggregateDataSetName` in interface `AggregateInformation`
    Returns:
      citation information about the aggregate dataset, or `null`.

  - ### setAggregateDataSetName

    @Deprecated(since="1.0") public void setAggregateDataSetName(Citation newValue)
    Deprecated.
    As of ISO 19115:2014, replaced by `DefaultAssociatedResource​.setName(Citation)`.
    Sets the citation information about the aggregate dataset.
    Parameters:
      `newValue` - the new citation.

  - ### getAggregateDataSetIdentifier

    @Deprecated(since="1.0") public Identifier getAggregateDataSetIdentifier()
    Deprecated.
    As of ISO 19115:2014, replaced by the first identifier of `getAggregateDataSetName()`.
    Identification information about aggregate dataset.
    Specified by:
      `getAggregateDataSetIdentifier` in interface `AggregateInformation`
    Returns:
      identification information about aggregate dataset, or `null`.

  - ### setAggregateDataSetIdentifier

    @Deprecated(since="1.0") public void setAggregateDataSetIdentifier(Identifier newValue)
    Deprecated.
    As of ISO 19115:2014, replaced by an identifier of `getAggregateDataSetName()`.
    Sets the identification information about aggregate dataset.
    Parameters:
      `newValue` - the new identifier.
