Method Detail

refreshIndex

boolean refreshIndex(java.lang.Object key)

Rebuilds the index associated to an object identified by the given key

Parameters:

key - an object's key

Returns:

true if the index could be refreshed

getSpatialindex

AbstractSpatialIndex getSpatialindex()

Gets the underlying implementation used to perform spatial-indexing

Returns:

an AbstractSpatialIndex instance

get

V get(java.lang.Object key)

Gets the object identified by the given key

Parameters:

key - an object's key

Returns:

the object associated to the key or null if no object is related to the key

get

V get(java.awt.geom.Point2D point,
      double tolerance)

Gets the element which is closer to the given point but within the tolerance.

Parameters:

point - a spatial point

tolerance - the maximum distance an element can be from the point to be selected

Returns:

the element closest to the given point with a distance equal or less to the tolerance

getAll

java.util.Collection<V> getAll(java.awt.geom.Point2D point,
                               double tolerance)

Gets all the elements which distance to the given point is within the tolerance

Parameters:

point - a spatial point

tolerance - tolerance the maximum distance an element can be from the point to be selected

Returns:

a collection containing all the elements which distance to the given point is within the tolerance

getAnyInteract

java.util.Collection<V> getAnyInteract(java.awt.geom.Rectangle2D mbr)

Gets all the elements interacting in some way with the given rectangle

Parameters:

mbr - a rectangle

Returns:

a collection containing all the elements interacting in some way with the given rectangle

getAnyInteract

java.util.Collection<V> getAnyInteract(java.awt.geom.Area area)

Gets all the elements interacting in some way with the given area

Parameters:

area - a java area

Returns:

a collection containing all the elements interacting in some way with the given area
