//
// FormatDataLibrary.h
//
// Functions that convert data into
// FFormatArgumentData structs, so that the data
// can be passed to FText::Format.
// The 'Format Message' and 'Format Log Message' nodes can format
// ints, strings, vectors, and more. To support a new data type,
// all you need to do is implement a blueprint-callable conversion
// function like this one:
//
// UFUNCTION(BlueprintPure, meta = (BlueprintInternalUseOnly = "true"))
// static FFormatArgumentData FormatArgumentDataBool(bool AutoConvertedValue, const FString &Name);
//
// This conversion function must have three things:
//
// * It returns FFormatArgumentData
// * It accepts 'AutoConvertedValue', the value you want to format,
// * It accepts 'Name', which must be copied into the FFormatArgumentData.
//
// The parameter names are required: you must use exactly these parameter
// names if you want this to act as a conversion function. You can put a
// conversion function like that anywhere in the system, in any UCLASS.
// This module will find and use it.
//
// This file also contains the built-in converters for standard types.
