Description of the class of information covered by the information.
The following properties are mandatory or conditional (i.e. mandatory under some circumstances)
in a well-formed metadata according ISO 19115:
ISO 19115 defines
MD_ScopeDescription
├─attributeInstances…… Attribute instances to which the information applies.
├─attributes………………………… Attributes to which the information applies.
├─dataset………………………………… Dataset to which the information applies.
├─featureInstances………… Feature instances to which the information applies.
├─features……………………………… Features to which the information applies.
└─other……………………………………… Class of information that does not fall into the other categories to which the information applies.ScopeDescription as an union (in the C/C++ sense):
only one of the properties in this class can be set to a non-empty value.
Setting any property to a non-empty value discard all the other ones.
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
XMLinstead.

DefaultScopeDescription
public DefaultScopeDescription()Creates an initially empty scope description. -
DefaultScopeDescription
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.If the given object contains more than one value, then the first non-null element in the following list has precedence (from wider scope to smaller scope): dataset, features, attributes, feature instances, attribute instances and other.
- Parameters:
object- the metadata to copy values from, ornullif 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
DefaultScopeDescription, then it is returned unchanged. - Otherwise a new
DefaultScopeDescriptioninstance 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, ornullif none.- Returns:
- a SIS implementation containing the values of the given object (may be the
given object itself), or
nullif the argument was null.
- If the given object is
-
getLevel
Returns an indication of which property is set, ornullif unknown. This method returns one of the following values depending which property has been set:hierarchical level of the data Scope code Getter method DATASETgetDataset()FEATURE_TYPEgetFeatures()ATTRIBUTE_TYPEgetAttributes()FEATUREgetFeatureInstances()ATTRIBUTEgetAttributeInstances()- Returns:
- an identification of the property which is set, or
nullif unknown. - Since:
- 1.0

-
getDataset
Returns the dataset to which the information applies.Example
If a geographic data provider is generating vector mapping for the administrative areas and if the data were processed in the same way, then the provider could record the bulk of initial data atScopeCode.DATASETlevel with a “Administrative area A, B & C” description.- Specified by:
getDatasetin interfaceScopeDescription- Returns:
- dataset to which the information applies, or
null.
-
setDataset
Sets the dataset to which the information applies.Effect on other properties
If and only if thenewValueis non-null, then this method automatically discards all other properties.- Parameters:
newValue- the new dataset.
-
getFeatures
Returns the feature types to which the information applies.Example
If an administrative area performs a complete re-survey of the road network, the change can be recorded atScopeCode.FEATURE_TYPElevel with a “Administrative area A — Road network” description.Conditions
This method returns a modifiable collection only if no other property is set. Otherwise, this method returns an unmodifiable empty collection.Upcoming API change: The type of this property may be changed toSet<CharSequence>for ISO 19115:2014 conformance. See GEO-238 for more information.- Specified by:
getFeaturesin interfaceScopeDescription- Returns:
- feature types to which the information applies.
-
setFeatures
Sets the feature types to which the information applies.Effect on other properties
If and only if thenewValueis non-empty, then this method automatically discards all other properties.Upcoming API change: The type of this property may be changed toSet<CharSequence>for ISO 19115:2014 conformance. See GEO-238 for more information.- Parameters:
newValues- the new feature types.
-
getAttributes
Returns the attribute types to which the information applies.Example
if an administrative area detects an anomaly in all overhead clearance of the road survey, the correction can be recorded atScopeCode.ATTRIBUTE_TYPElevel with a “Administrative area A — Overhead clearance” description.Conditions
This method returns a modifiable collection only if no other property is set. Otherwise, this method returns an unmodifiable empty collection.Upcoming API change: The type of this property may be changed toSet<CharSequence>for ISO 19115:2014 conformance.
