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.

AllowReplacements	whether to allow character replacements (change one character into another) as a single operation, rather than as two operations (an insertion and a removal).
MaxEditDistance	If 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.

◆ getAsInteger() [3/3]

bool StringRef::getAsInteger	(	unsigned	Radix,
		APInt &	Result
	)		const

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.

void StringRef::split	(	SmallVectorImpl< StringRef > &	A,
		StringRef	Separator,

Split into substrings around the occurrences of a separator string.

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.
