Description
The MimeTypeMapper is the entry point in DDF for resolving file extensions to mime types, and vice versa.
MimeTypeMappers are used by the ResourceReader to determine the file extension for a given mime type in aid of retrieving a product. MimeTypeMappers are also used by the FileSystemProvider in the Content Framework to read a file from the content file repository.
The MimeTypeMapper maintains a list of all of the MimeTypeResolvers in DDF.
The MimeTypeMapper accesses each MimeTypeResolver, according to its priority, until the provided file extension is successfully mapped to its corresponding mime type. If no mapping is found for the file extension, then null is returned for the mime type. Similarly, the MimeTypeMapper accesses each MimeTypeResolver, according to its priority, until the provided mime type is successfully mapped to its corresponding file extension.
