Detailed Description

Base class for any atlas cache which has flushing logic to keep the number of in use pages small

Member Function Documentation

RequestFlushCache()

virtual void FSlateFlushableAtlasCache::RequestFlushCache ( const FString &  Reason )

pure virtual

Called when this cache must be flushed

Parameters

Reason

A string explaining the reason the cache was flushed (generally for debugging or logging

Implemented in FSlateFontCache, and FSlateVectorGraphicsCache.

ResetFlushCounters()

void FSlateFlushableAtlasCache::ResetFlushCounters

(

)

Resets all counters to their initial state to start over flushing logic

UpdateFlushCounters()

void FSlateFlushableAtlasCache::UpdateFlushCounters	(	int32	NumGrayscale,
		int32	NumColor,
		int32	NumMsdf,
		int32	NumNonAtlased
	)

Increments counters that determine if a flush is needed. If a flush is needed RequestFlushCache will be called from here
