Detailed Description

template<typename T>
class llvm::ArrayRef< T >

ArrayRef - Represent a constant reference to an array (0 or more elements consecutively in memory), i.e. a start pointer and a length. It allows various APIs to take consecutive elements easily and conveniently.

This class does not own the underlying data, it is expected to be used in situations where the data resides in some other buffer, whose lifetime extends past that of the ArrayRef. For this reason, it is not in general safe to store an ArrayRef.

This is intended to be trivially copyable, so it should be passed by value.
