Method Detail

getIdentifiers

@UML(identifier="identifier",
     obligation=MANDATORY,
     specification=ISO_19115_2)
Collection<? extends Identifier> getIdentifiers()

Code used to identify the objective.

Returns:: objective identifiers.

getPriority

@UML(identifier="priority",
     obligation=OPTIONAL,
     specification=ISO_19115_2)
default InternationalString getPriority()

Priority applied to the target.

Returns:: priority applied, or null.

getTypes

@UML(identifier="type",
     obligation=OPTIONAL,
     specification=ISO_19115_2)
default Collection<? extends ObjectiveType> getTypes()

Collection technique for the objective.

Returns:: collection technique for the objective.

getFunctions

@UML(identifier="function",
     obligation=OPTIONAL,
     specification=ISO_19115_2)
default Collection<? extends InternationalString> getFunctions()

Role or purpose performed by or activity performed at the objective.

Returns:: role or purpose performed by or activity performed at the objective.

getExtents

@UML(identifier="extent",
     obligation=OPTIONAL,
     specification=ISO_19115_2)
default Collection<? extends Extent> getExtents()

Extent information including the bounding box, bounding polygon, vertical and temporal extent of the objective.

Returns:: extent information.

getObjectiveOccurences
```
@UML(identifier="objectiveOccurence",
     obligation=MANDATORY,
     specification=ISO_19115_2)
Collection<? extends Event> getObjectiveOccurences()
```
Event or events associated with objective completion.
Known typo: "occurrence" is missing a "r" in the UML diagram of ISO 19115-2 specification. The UML annotation below reflects that spelling. The method reflects that spelling in GeoAPI 3.1, but will be changed to getObjectiveOccurrences() in GeoAPI 4.0.

Returns:

events associated with objective completion.

getPass

@UML(identifier="pass",
     obligation=OPTIONAL,
     specification=ISO_19115_2)
default Collection<? extends PlatformPass> getPass()

Pass of the platform over the objective.

Returns:: pass of the platform.

getSensingInstruments

@UML(identifier="sensingInstrument",
     obligation=OPTIONAL,
     specification=ISO_19115_2)
default Collection<? extends Instrument> getSensingInstruments()

Instrument which senses the objective data.

Returns:: instrument which senses the objective data.
