# Class DefaultPlatform

Object
AbstractMetadata
ModifiableMetadata
ISOMetadata
DefaultPlatform

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

public class DefaultPlatform extends ISOMetadata implements Platform
Designation of the platform used to acquire the dataset. The following properties are mandatory in a well-formed metadata according ISO 19115:
`MI_Platform` `├─identifier………………` Unique identification of the platform. `│ └─code……………………` Alphanumeric value identifying an instance in the namespace. `├─description……………` Narrative description of the platform supporting the instrument. `└─instrument………………` Instrument(s) mounted on a platform. `├─identifier……` Unique identification of the instrument. `└─type……………………` Name of the type of instrument.

## 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

  - ### DefaultPlatform

    public DefaultPlatform()
    Constructs an initially empty platform.

  - ### DefaultPlatform

    public DefaultPlatform(Platform 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.
    See Also:
      - `castOrCopy(Platform)`

- ## Method Details

  - ### castOrCopy

    public static DefaultPlatform castOrCopy(Platform 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 `DefaultPlatform`, then it is returned unchanged.
    - Otherwise a new `DefaultPlatform` 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.

  - ### getCitation

    public Citation getCitation()
    Returns the source where information about the platform is described. `null` if unspecified.
    Specified by:
      `getCitation` in interface `Platform`
    Returns:
      source where information about the platform is described, or `null`.

  - ### setCitation

    public void setCitation(Citation newValue)
    Sets the source where information about the platform is described.
    Parameters:
      `newValue` - the new citation value.

  - ### getIdentifier

    public Identifier getIdentifier()
    Returns the unique identification of the platform.
    Specified by:
      `getIdentifier` in interface `Platform`
    Overrides:
      `getIdentifier` in class `ISOMetadata`
    Returns:
      unique identification of the platform, or `null`.

  - ### setIdentifier

    public void setIdentifier(Identifier newValue)
    Sets the unique identification of the platform.
    Overrides:
      `setIdentifier` in class `ISOMetadata`
    Parameters:
      `newValue` - the new identifier value.

  - ### getDescription

    public InternationalString getDescription()
    Gets the narrative description of the platform supporting the instrument.
    Specified by:
      `getDescription` in interface `Platform`
    Returns:
      narrative description of the platform, or `null`.

  - ### setDescription

    public void setDescription(InternationalString newValue)
    Sets the narrative description of the platform supporting the instrument.
    Parameters:
      `newValue` - the new description value.

  - ### getSponsors

    public Collection<ResponsibleParty> getSponsors()
    Returns the organization responsible for building, launch, or operation of the platform.
    Upcoming API change — generalization
    As of ISO 19115:2014, `ResponsibleParty` is replaced by the `Responsibility` parent interface. This change will be tentatively applied in GeoAPI 4.0.
    Specified by:
      `getSponsors` in interface `Platform`
    Returns:
      organization responsible for building, launch, or operation of the platform.

  - ### setSponsors

    public void setSponsors(Collection<? extends ResponsibleParty> newValues)
    Sets the organization responsible for building, launch, or operation of the platform.
    Upcoming API change — generalization
    As of ISO 19115:2014, `ResponsibleParty` is replaced by the `Responsibility` parent interface. This change will be tentatively applied in GeoAPI 4.0.
    Parameters:
      `newValues` - the new sponsors values;

  - ### getInstruments

    public Collection<Instrument> getInstruments()
    Gets the instrument(s) mounted on a platform.
    Specified by:
      `getInstruments` in interface `Platform`
    Returns:
      instrument(s) mounted on a platform.

  - ### setInstruments
