Description

A MimeTypeResolver is a DDF service that can map a file extension to its corresponding mime type, and conversely, can map a mime type to its file extension.

MimeTypeResolvers are assigned a priority (0-100, with the higher the number indicating the higher priority). This priority is used to sort all of the MimeTypeResolvers in the order they should be checked for mapping a file extension to a mime type (or vice versa). This priority also allows custom MimeTypeResolvers to be invoked before default MimeTypeResolvers if the custom resolver's priority is set higher than the default's.

MimeTypeResolvers are not typically invoked directly. Rather, the MimeTypeMapper maintains a list of MimeTypeResolvers (sorted by their priority) that it invokes to resolve a mime type to its file extension (or to resolve a file extension to its mime type).
