NSServicesRequests — Mac OS X 10.0
This informal protocol declares the two methods
writeSelectionToPasteboard:types
: and
readSelectionFromPasteboard
:, which classes may
implement to interact with system services found in the Services
menu. The first of these,
writeSelectionToPasteboard:types
:, is used to
provide data to a service, while
readSelectionFromPasteboard
: is used to retrieve
data from a service.
