IsObjCSynthesizedPropertyExplicitParameter()

bool IsObjCSynthesizedPropertyExplicitParameter ( VarDecl const * VD )

static

Returns true if the specified variable VD is an explicit parameter of a synthesized Objective-C property accessor.

E.g., a synthesized property setter method will have a single explicit parameter which is the property to set.
