- All Implemented Interfaces:
FeatureSet
,java.lang.Iterable<Feature>
public final class RelatedFeatureQueryResult extends java.lang.Object implements FeatureSet
Represents the results of a related tables query. This iterator traverses the features found by the query.A prerequisite for querying related features is that all the participating tables must be part of a map, as either feature layers or non-spatial tables.
Example usage:
List<RelatedFeatureQueryResult> relatedFeatureQueryResultList = relatedFeatureQueryResultFuture.get(); //iterate over returned RelatedFeatureQueryResults for(RelatedFeatureQueryResult relatedQueryResult : relatedFeatureQueryResultList){ //iterate over Features returned for (Feature relatedFeature : relatedQueryResult) { ArcGISFeature agsFeature = (ArcGISFeature) relatedFeature; } }

Method Detail
-
getFields
public java.util.List<Field> getFields()
Description copied from interface:FeatureSet
Gets the fields of the feature set.- Specified by:
getFields
in interfaceFeatureSet
- Returns:
- the fields of the feature set
-
getGeometryType
public GeometryType getGeometryType()
Description copied from interface:FeatureSet
Gets the geometry type of the feature set.- Specified by:
getGeometryType
in interfaceFeatureSet
- Returns:
- a geometry type
-
getSpatialReference
public SpatialReference getSpatialReference()
Description copied from interface:FeatureSet
Gets the spatial reference of the feature set.- Specified by:
getSpatialReference
in interfaceFeatureSet
- Returns:
- a spatial reference
-
iterator
public java.util.Iterator<Feature> iterator()
Returns a new iterator over the set of features. Iterators previously returned from this method will become invalid and their methods will throw an IllegalStateException.- Specified by:
iterator
in interfacejava.lang.Iterable<Feature>
- Returns:
- a new iterator over the set of features in this RelatedFeatureQueryResult
- Since:
- 100.1.0
-
getFeature
public ArcGISFeature getFeature()
Gets the feature for which related features were queried.- Returns:
- the feature
- Since:
- 100.1.0
-
getRelationshipInfo
public RelationshipInfo getRelationshipInfo()
Gets the relationship info for this query result.- Returns:
- the relationship info
- Since:
- 100.1.0
-
isTransferLimitExceeded
public boolean isTransferLimitExceeded()
Gets if the transfer limit on the service was exceeded.- Returns:
- true if the transfer limit was exceeded, false otherwise
- Since:
- 100.1.0
-
getRelatedTable
public ArcGISFeatureTable getRelatedTable()
Gets the related table for this query result. There can be more than one instance of the same table or layer on the map with different scale level visibility, definition expression, and so on. All such instances share the same RelationshipInfo with the table the query operation is called on. In such cases, results from all such instances are returned, and the relatedTable property is used to distinguish between them.- Returns:
- the related table
