Detailed Description

A table of known extensions, searchable by name or field number. When parsing a protocol message that might have extensions, you must provide a GPBExtensionRegistry in which you have registered any extensions that you want to be able to parse. Otherwise, those extensions will just be treated like unknown fields.

The *Root classes provide +extensionRegistry for the extensions defined in a given file and all files it imports. You can also create a GPBExtensionRegistry, and merge those registries to handle parsing extensions defined from non overlapping files.

GPBExtensionRegistry *registry =
    [[[MyProtoFileRoot extensionRegistry] copy] autorelease];
[registry addExtension:[OtherMessage neededExtension];  // Not in MyProtoFile
NSError *parseError = nil;
MyMessage *msg = [MyMessage parseData:data
                    extensionRegistry:registry
                                error:&parseError];
