Class TRbwIntervalTree

Unit

IntervalTree

Declaration

type TRbwIntervalTree = class(TObject)

Description

TRbwIntervalTree is used to find objects that enclose a particular location. For each dimension of the object there must be a TIntervalDefinition that defines the extents for all objects to be added to TRbwIntervalTree and a procedure for determining the extent of the object being added. The TIntervalDefinitions are contained in a TIntDefArray that is passed to TRbwIntervalTree in Create. FindContainingObjects is used to find the objects that contain a particular location. The location is specified in a TOneDRealArray which must have the same length as the TIntDefArray passed in the constructor.
