final class MapToMapConverter extends java.lang.Object implements ConditionalGenericConverter
First, creates a new Map of the requested targetType with a size equal to the size of the source Map. Then copies each element in the source map to the target map. Will perform a conversion from the source maps's parameterized K,V types to the target map's parameterized types K,V if necessary.
