Detailed Description

Class that provides an interface over a binding operation.

This class does not represent a structure that exists in the Mach-O format specifications but it provides a view of a binding operation that is performed by the Dyld binding bytecode (LC_DYLD_INFO) or the Dyld chained fixups (DYLD_CHAINED_FIXUPS)
