This class allows to walk through all fields of single document using instance of {@link ODocumentFieldVisitor} class.Only current document and embedded documents will be walked. Which means that all embedded collections will be visited too and all embedded documents which are contained in this collections also will be visited. Fields values can be updated/converted too. If method {@link ODocumentFieldVisitor#visitField(OType,OType,Object)} will returnnew value original value will be updated but returned result will not be visited by {@link ODocumentFieldVisitor} instance.If currently processed value is collection or map of embedded documents or embedded document itself then method {@link ODocumentFieldVisitor#goDeeper(OType,OType,Object)} is called, if it returns false then this collection will not bevisited by {@link ODocumentFieldVisitor} instance.Fields will be visited till method {@link ODocumentFieldVisitor#goFurther(OType,OType,Object,Object)} returns true.
