ComparisonCategoryResult Compare(const T &X, const T &Y)

Helper to compare two comparable types.

The JSON file list parser is used to communicate input to InstallAPI.

ComparisonCategoryResult

An enumeration representing the possible results of a three-way comparison.

const FunctionProtoType * T
