class StringSwitch

Declaration

template <typename T, typename R = T>
class StringSwitch { /* full declaration omitted */ };

Description

A switch()-like statement whose cases are string literals. The StringSwitch class is a simple form of a switch() statement that determines whether the given string matches one of the given string literals. The template type parameter \p T is the type of the value that will be returned from the string-switch expression. For example, the following code switches on the name of a color in \c argv[i]:

Templates

T
R = T

Member Variables

private const llvm::StringRef Str
The string we are matching.
private Optional<T> Result
The pointer to the result of this switch statement, once known, null before that.
