83// This class is an abstract interface via which the URL class accesses
84// net access services. When any source URL is not in effect a local file
85// path, then the URL class is used to look at it. Then the URL class can
86// be asked to make a binary input stream via which the referenced resource
87// can be read in.
88//
89// The URL class will use an object derived from this class to create a
90// binary stream for the URL to return. The object it uses is provided by
91// the platform utils, and is actually provided by the per-platform init
92// code so each platform can decide what actual implementation it wants to
93// use.
