public class DefaultExtent
extends ISOMetadata
implements org.opengis.metadata.extent.Extent
Information about spatial, vertical, and temporal extent.
The following properties are mandatory or conditional (i.e. mandatory under some circumstances)
in a well-formed metadata according ISO 19115:
This type has four conditional properties:
geographic elements,
temporal elements,
vertical elements and
description.
At least one of the four shall be used.
EX_Extent
├─description……………………
The spatial and temporal extent for the referring object.
├─geographicElement……
Geographic component of the extent of the referring object.
├─temporalElement…………
Temporal component of the extent of the referring object.
│ └─extent………………………
The date and time for the content of the dataset.
└─verticalElement…………
Vertical component of the extent of the referring object.
├─minimumValue………
The lowest vertical extent contained in the dataset.
├─maximumValue………
The highest vertical extent contained in the dataset.
└─verticalCRS…………
Information about the vertical coordinate reference system.In addition to the standard properties, SIS provides the following methods:
addElements(Envelope)
for adding extents inferred from the given envelope.Extents.getGeographicBoundingBox(Extent)
for extracting a global geographic bounding box.
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.

DefaultExtent
public DefaultExtent()Constructs an initially empty extent. -
DefaultExtent
public DefaultExtent(CharSequence description, org.opengis.metadata.extent.GeographicExtent geographicElements, org.opengis.metadata.extent.VerticalExtent verticalElements, org.opengis.metadata.extent.TemporalExtent temporalElements) Constructs an extent initialized to the given description or components. Any argument given to this constructor can benull
. While a validExtent
requires at least one component to be non-null, this constructor does not perform such verification.- Parameters:
description
- a description, ornull
if none.geographicElements
- a geographic component, ornull
if none.verticalElements
- a vertical component, ornull
if none.temporalElements
- a temporal component, ornull
if none.
-
DefaultExtent
public DefaultExtent(org.opengis.metadata.extent.Extent 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, ornull
if none.- See Also:
-
-
Method Details
-
castOrCopy
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 returnsnull
. - Otherwise if the given object is already an instance of
DefaultExtent
, then it is returned unchanged. - Otherwise a new
DefaultExtent
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, ornull
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.
- If the given object is

Returns a non-null value if this extent is non-empty. This implementation does not test if the elements are themselves empty. -
addElements
public void addElements(org.opengis.geometry.Envelope envelope) throws org.opengis.referencing.operation.TransformException Adds geographic, vertical or temporal extents inferred from the given envelope. This method inspects the envelope CRS and creates aGeographicBoundingBox
,VerticalExtent
orTemporalExtent
elements as needed.Note: this method is available only if the referencing module is on the classpath.
- Parameters:
envelope
- the envelope to use for inferring the additional extents.- Throws:

This method computes the intersections of all geographic, vertical and temporal elements in this extent with all geographic, vertical and temporal elements in the other extent, ignoring duplicated results.- Parameters:
other
- the extent to intersect with this extent.- Throws:
IllegalArgumentException
- if two elements to intersect are not compatible (e.g. mismatched bounding box inclusion status or mismatched vertical datum).UnsupportedOperationException
