Pr22.ECardHandling.File

public class File
extends java.lang.Object

ECard file identifier class. Generally ECards contain data in files called Data Groups. Different type of documents (e.g. ePassport and ISO-DL) stores the same data in different data group. Our SDK contains logical file identifiers to identify data groups by their content next to the numerical file identifiers DG(int). Both of them are usable in certain situations. They can be converted to each other by the ECard.convertFileId(Pr22.ECardHandling.File) method.
