Public function FString  
Public function Const const FString & Get the unique identifier for this perf counter instance
Public function double

GetNumber ( const FString& Name,
double DefaultValue
)

 Returns currently held value, or DefaultValue if none
Public function int32

Increment ( const FString& Name,
int32 Add,
int32 DefaultValue,
uint32 Flags
)

 Convenience method for incrementing a transient counter.

Public function TPerformanceHistogramMap & Returns performance histograms for direct manipulation by the client code.
Public function bool

ReportUnplayableCondition ( const FString& ConditionDescription
)

 Reports an unplayable condition.
Public function void Clears transient perf counters, essentially marking beginning of a new stats period
Public function void

Set ( const FString& Name,
int64 Val,
uint32 Flags
)

  
Public function void

Set ( const FString& Name,
double Val,
uint32 Flags
)

uint32 Flags
)

  
Public function void

Set ( const FString& Name,
uint64 Val,
uint32 Flags
)

  
Public function void

Set ( const FString& Name,
int32 Val,
uint32 Flags
)

 Set overloads (use these)
Public function void

SetJson ( const FString& Name,
const FProduceJsonCounterValue& Callback,
uint32 Flags
)

 Make a callback so we can request more extensive types on demand (presumably backed by some struct locally)
Public function void

SetNumber ( const FString& Name,
double Value,
uint32 Flags
)

 Maps value to a numeric holder
Public function void

SetString ( const FString& Name,
const FString& Value,
uint32 Flags
)

 Maps value to a string holder
Public function bool

StartMachineLoadTracking ( double TickRate,
const TArray< double >& FrameTimeHistogramBucketsMs
)

 Starts tracking overall machine load (empty array will use default hitch buckets).
Public function bool Starts tracking overall machine load.
Public function bool Stops tracking overall machine load.
