Detailed Description

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.

Otherthe string to compare this string against.
AllowReplacementswhether to allow character replacements (change one character into another) as a single operation, rather than as two operations (an insertion and a removal).
MaxEditDistanceIf non-zero, the maximum edit distance that this routine is allowed to compute. If the edit distance will exceed that maximum, returns MaxEditDistance+1.
Returns
the minimum number of character insertions, removals, or (if AllowReplacements is true) replacements needed to transform one of the given strings into the other. If zero, the strings are identical.

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.

◆ getAsInteger() [2/2]

template<typename T >
bool llvm::StringRef::getAsInteger ( unsigned  Radix,

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.

◆ slice()

StringRef llvm::StringRef::slice ( size_t  Start,

) const
inline

Return a reference to the substring from [Start, End).

Parameters
StartThe index of the starting character in the substring; if the index is npos or greater than the length of the string then the empty substring will be returned.
EndThe index following the last character to include in the substring. If this is npos or exceeds the number of characters remaining in the string, the string suffix (starting with Start) will be returned. If this is less than Start, an empty string will be returned.

◆ split() [1/4]

std::pair< StringRef, StringRef > llvm::StringRef::split ( char  Separator) const
inline

Split into two substrings around the first occurrence of a separator character.

If Separator is in the string, then the result is a pair (LHS, RHS) such that (*this == LHS + Separator + RHS) is true and RHS is maximal. If Separator is not in the string, then the result is a pair (LHS, RHS) where (*this == LHS) and (RHS == "").

Parameters
SeparatorThe character to split on.
Returns
The split substrings.

◆ split() [2/4]

void StringRef::split ( SmallVectorImpl< StringRef > &  A,
char  Separator,
int  MaxSplit = -1,
bool  KeepEmpty = true 
) const

Split into substrings around the occurrences of a separator character.

Each substring is stored in A. If MaxSplit is >= 0, at most MaxSplit splits are done and consequently <= MaxSplit + 1 elements are added to A. If KeepEmpty is false, empty strings are not added to A. They still count when considering MaxSplit An useful invariant is that Separator.join(A) == *this if MaxSplit == -1 and KeepEmpty == true

Parameters
A- Where to put the substrings.
Separator- The string to split on.
MaxSplit- The maximum number of times the string is split.
KeepEmpty- True if empty substring should be added.
