Detailed Description

MapFeatureVisitor is a realization of the Visitor design pattern for MapFeature. It allows the features to differentiate themselves so that type-specific processing can occur on the feature.

Parameters

<T>	the return type that the visit method will return. If nothing will be returned, use Void and return null.
