# Class DefaultDigitalTransferOptions

DefaultDigitalTransferOptions

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

public class DefaultDigitalTransferOptions extends ISOMetadata implements DigitalTransferOptions
Technical means and media by which a resource is obtained from the distributor.

## 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.

- ## Constructor Details

  - ### DefaultDigitalTransferOptions

    public DefaultDigitalTransferOptions()
    Constructs an initially empty digital transfer options.

  - ### DefaultDigitalTransferOptions

    public DefaultDigitalTransferOptions(DigitalTransferOptions 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.
    Note on properties validation: This constructor does not verify the property values of the given metadata (e.g. whether it contains unexpected negative values). This is because invalid metadata exist in practice, and verifying their validity in this copy constructor is often too late. Note that this is not the only hole, as invalid metadata instances can also be obtained by unmarshalling an invalid XML document.
    Parameters:
      `object` - the metadata to copy values from, or `null` if none.
    See Also:
      - `castOrCopy(DigitalTransferOptions)`

- ## Method Details

  - ### castOrCopy

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

  - ### getUnitsOfDistribution

    public InternationalString getUnitsOfDistribution()
    Returns tiles, layers, geographic areas, etc., in which data is available.
    Specified by:
      `getUnitsOfDistribution` in interface `DigitalTransferOptions`
    Returns:
      tiles, layers, geographic areas, etc. in which data is available, or `null`.

  - ### setUnitsOfDistribution

    public void setUnitsOfDistribution(InternationalString newValue)
    Sets tiles, layers, geographic areas, etc., in which data is available.
    Parameters:
      `newValue` - the new units of distribution.

  - ### getTransferSize

    @ValueRange(minimum=0.0, isMinIncluded=false) public Double getTransferSize()
    Returns an estimated size of a unit in the specified transfer format, expressed in megabytes. The transfer size is greater than zero.
    Specified by:
      `getTransferSize` in interface `DigitalTransferOptions`
    Returns:
      estimated size of a unit in the specified transfer format in megabytes, or `null`.

  - ### setTransferSize

    public void setTransferSize(Double newValue)
    Sets an estimated size of a unit in the specified transfer format, expressed in megabytes. The transfer shall be greater than zero.
