# Class DefaultAcquisitionInformation

Object
AbstractMetadata
ModifiableMetadata
ISOMetadata
DefaultAcquisitionInformation

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

public class DefaultAcquisitionInformation extends ISOMetadata implements AcquisitionInformation
Designations for the measuring instruments, the platform carrying them, and the mission to which the data contributes.

## 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

  - ### DefaultAcquisitionInformation

    public DefaultAcquisitionInformation()
    Constructs an initially empty acquisition information.

  - ### DefaultAcquisitionInformation

    public DefaultAcquisitionInformation(AcquisitionInformation 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(AcquisitionInformation)`

- ## Method Details

  - ### castOrCopy

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

  - ### getAcquisitionPlans

    public Collection<Plan> getAcquisitionPlans()
    Returns the plan as implemented by the acquisition.
    Specified by:
      `getAcquisitionPlans` in interface `AcquisitionInformation`
    Returns:
      plan as implemented by the acquisition.

  - ### setAcquisitionPlans

    public void setAcquisitionPlans(Collection<? extends Plan> newValues)
    Sets the plan as implemented by the acquisition.
    Parameters:
      `newValues` - the new plan values.

  - ### getAcquisitionRequirements

    public Collection<Requirement> getAcquisitionRequirements()
    Returns the requirement the data acquisition intends to satisfy.
    Specified by:
      `getAcquisitionRequirements` in interface `AcquisitionInformation`
    Returns:
      requirement the data acquisition intends to satisfy.

  - ### setAcquisitionRequirements

    public void setAcquisitionRequirements(Collection<? extends Requirement> newValues)
    Sets the requirement the data acquisition intends to satisfy.
    Parameters:
      `newValues` - the new acquisition requirements values.

  - ### getEnvironmentalConditions

    public EnvironmentalRecord getEnvironmentalConditions()
    Returns a record of the environmental circumstances during the data acquisition. `null` if unspecified.
    Specified by:

    Returns:
      record of the environmental circumstances, or `null`.

  - ### setEnvironmentalConditions
