Provides access to a set of generic methods that can be used in all languages supported.
Description
The IGeometryBridge methods can be used with any supported development languages: Java, C#, VB.Net, VB 6.0, C++, etc... The methods on the regular interfaces (IGeometryCollection, ISegmentCollection, IPointCollection, etc) are using C style arrays, which are not supported by some languages; the IGeometryBridge interface is there to solve that problem allowing to pass safe arrays instead.
