- All Implemented Interfaces:

,GeometricObjects
Number of objects, listed by geometric object type, used in the dataset.
The following property is mandatory in a well-formed metadata according ISO 19115:
MD_GeometricObjects
└─geometricObjectType……
Name of point and vector spatial objects used to locate zero-, one-, and two-dimensional spatial locations in the dataset.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.

DefaultGeometricObjects
public DefaultGeometricObjects()Constructs an initially empty geometric objects. -
DefaultGeometricObjects
Creates a geometric object initialized to the given type.- Parameters:
geometricObjectType
- total number of the point or vector object type occurring in the dataset.
-
DefaultGeometricObjects
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.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, 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
DefaultGeometricObjects
, then it is returned unchanged. - Otherwise a new
DefaultGeometricObjects
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
-
getGeometricObjectType
Returns the total number of the point or vector object type occurring in the dataset.- Specified by:
getGeometricObjectType
in interfaceGeometricObjects
- Returns:
- name of spatial objects used to locate spatial locations in the dataset, or
null
.
-
setGeometricObjectType
Sets the total number of the point or vector object type occurring in the dataset.- Parameters:
newValue
- the new geometric object type.
-
getGeometricObjectCount
Returns the total number of the point or vector object type occurring in the dataset.- Specified by:
getGeometricObjectCount
in interfaceGeometricObjects
- Returns:
- total number of the point or vector object type, or
null
.
-
setGeometricObjectCount
Sets the total number of the point or vector object type occurring in the dataset.- Parameters:
newValue
- the geometric object count, ornull
.- Throws:
IllegalArgumentException
- if the given value is zero or negative.
