Smart pointer class that efficiently represents Objective-C method names.

This class will either point to an IdentifierInfo or a MultiKeywordSelector (which is private). This enables us to optimize selectors that take no arguments and selectors that take 1 argument, which accounts for 78% of all selectors in Cocoa.h.

◆ getEmptyMarker()

static Selector clang::Selector::getEmptyMarker ( )	inlinestatic

◆ getIdentifierInfoForSlot()

Retrieve the identifier at a given position in the selector.

Note that the identifier pointer returned may be NULL. Clients that only care about the text of the identifier string, and not the specific, uniqued identifier pointer, should use [getNameForSlot()](classclang%5F1%5F1Selector.html#a1e7674118587ab893c3676b7aa980263 "Retrieve the name at a given position in the selector."), which returns an empty string when the identifier pointer would be NULL.

Parameters

argIndex	The index for which we want to retrieve the identifier. This index shall be less than getNumArgs() unless this is a keyword selector, in which case 0 is the only permissible value.

Returns

the uniqued identifier for this slot, or NULL if this slot has no corresponding identifier.

◆ getInstTypeMethodFamily()

◆ getNameForSlot()

StringRef Selector::getNameForSlot	(	unsigned	argIndex	)	const

Retrieve the name at a given position in the selector.

Parameters

argIndex	The index for which we want to retrieve the name. This index shall be less than getNumArgs() unless this is a keyword selector, in which case 0 is the only permissible value.

Returns

the name for this slot, which may be the empty string if no name was supplied.
