Create()

IMemoryChunkStore * BuildPatchServices::FMemoryChunkStoreFactory::Create ( int32  ChunkCount, IChunkEvictionPolicy *  EvictionPolicy, IChunkStore *  OverflowStore, IMemoryChunkStoreStat *  MemoryChunkStoreStat, IChunkReferenceTracker *  InOptionalChunkReferenceTracker  )

static

Creates an instance of a chunk store class that stores chunks in memory. When Put() is called and the store has >= ChunkCount entries, the EvictionPolicy will be used to select chunks which should be Put() into the OverflowStore instance, and removed from this store. If the EvictionPolicy allows it, the store will grow larger than ChunkCount. When Get() is called on a chunk that is not in this store, Remove() will be attempted on the OverflowStore instance, and the chunk will enter the memory store if it was successful.

Parameters

ChunkCount	The size of the store, at which point chunks will start being evicted based on the policy provided.
EvictionPolicy	Required ptr to an eviction policy that will be used to clean out the store, and evict data when full.
OverflowStore	Required ptr to an IChunkStore which will be used as an overflow for evicted chunks.
MemoryChunkStoreStat	Required ptr to the statistics class.

Returns

the new IMemoryChunkStore instance created.
