◆ GetFormatterPrefixSuffix()

std::pair< llvm::StringRef, llvm::StringRef > Language::GetFormatterPrefixSuffix ( llvm::StringRef  type_hint)
virtual

An individual data formatter may apply to several types and cross language boundaries.

Each of those languages may want to customize the display of values of said types by appending proper prefix/suffix information in language-specific ways. This function returns that prefix and suffix.

Parameters
[in]type_hintA StringRef used to determine what the prefix and suffix should be. It is called a hint because some types may have multiple variants for which the prefix and/or suffix may vary.
Returns
A std::pair<StringRef, StringRef>, the first being the prefix and the second being the suffix. They may be empty.
