LLVM: llvm::StringRef Class Reference (original) (raw)

StringRef - Represent a constant reference to a string, i.e. More...

#include "[llvm/ADT/StringRef.h](StringRef%5F8h%5Fsource.html)"

StringRef - Represent a constant reference to a string, i.e.

a character array and a length, which need not be null terminated.

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

◆ consume_front_insensitive()

◆ consumeInteger() [1/2]

Parse the current string as an integer of the specified Radix.

If Radix is specified as zero, this does radix autosensing using extended C rules: 0 is octal, 0x is hex, 0b is binary.

If the string does not begin with a number of the specified radix, this returns true to signify the error. The string is considered erroneous if empty. The portion of the string representing the discovered numeric value is removed from the beginning of the string.

◆ consumeInteger() [2/2]

template<typename T>

Parse the current string as an integer of the specified radix.

If Radix is specified as zero, this does radix autosensing using extended C rules: 0 is octal, 0x is hex, 0b is binary.

If the string does not begin with a number of the specified radix, this returns true to signify the error. The string is considered erroneous if empty or if it overflows T. The portion of the string representing the discovered numeric value is removed from the beginning of the string.

◆ getAsInteger() [1/2]

Parse the current string as an integer of the specified Radix, or of an autosensed radix if the Radix given is 0.

The current value in Result is discarded, and the storage is changed to be wide enough to store the parsed integer.

Returns

true if the string does not solely consist of a valid non-empty number in the appropriate base.

APInt::fromString is superficially similar but assumes the string is well-formed in the given radix.

◆ getAsInteger() [2/2]

template<typename T>

Parse the current string as an integer of the specified radix.

If Radix is specified as zero, this does radix autosensing using extended C rules: 0 is octal, 0x is hex, 0b is binary.

If the string is invalid or if only a subset of the string is valid, this returns true to signify the error. The string is considered erroneous if empty or if it overflows T.
