Methods

Explore(Double[], Double, Func<T, Boolean>)

Performs a circle query to retrieve all vector-features intersecting the circle.
Declaration
IEnumerable<T> Explore(double[] source, double radius, Func<T, bool> predicate = null)
Parameters
Type Name Description
System.Double[] source The outgoing position (lat, lon) from which to start the circle query.
System.Double radius The radius in meter to specify the circle range.
System.Func<T, System.Boolean> predicate The optional predicate to filter out specific features
Returns
Type Description
System.Collections.Generic.IEnumerable<T> Returns a sequence of objects intersecting the specified circle and optional predicate.

Insert(IDomainData)

Inserts and initializes a new vector feature and making it available on the layer defined by their IVectorFeature
Declaration
T Insert(IDomainData data)
Parameters
Type Name Description
IDomainData data The data to passionate.
Returns
Type Description
T Returns the new feature object if the feature was successfully inserted.

Nearest(Double[], Func<T, Boolean>)

Tries to find the nearest domain object for given parameters.
Declaration
T Nearest(double[] position, Func<T, bool> predicate = null)
Parameters
Type Name Description
System.Double[] position The outgoing position (lat, lon) from which to start the query.
System.Func<T, System.Boolean> predicate The optional predicate to filter out specific features
Returns
Type Description
T The found T or null if none could be found.

Remove(T)

Removes the feature item from the layer.
Declaration
void Remove(T entity)
Parameters
Type Name Description
T entity The entity and position to remove
