llvm::StringRef str1("hello");
llvm::StringRef str2("world");
int result = str1.compare(str2);
if (result < 0) {
std::cout << "str1 is less than str2" << std::endl;
} else if (result > 0) {
std::cout << "str1 is greater than str2" << std::endl;
} else {
std::cout << "str1 is equal to str2" << std::endl;
}
// Assume that we have a vector of StringRef objects called vec
// We want to sort the vector in ascending order using the compare function
std::sort(vec.begin(), vec.end(), [](llvm::StringRef left, llvm::StringRef right) {
return left.compare(right) < 0;
});
This example shows how to use the StringRef compare function with the std::sort function to sort a vector of StringRef objects in ascending order. The lambda function passed to std::sort uses the compare function to determine if one StringRef object is less than the other, and returns a boolean value indicating the result.
Package Library:
The StringRef class is part of the LLVM project. Therefore, the package library for the StringRef class would be LLVM.bool StringParser::StringTo(const StringRef& inString, int base /*= 10*/)
{
if (inString.Length() != 4)
{
return false;
}
return inString.Compare("TRUE", true) == 0;
}
