DataChunker Class Reference #include <dataChunker.h> Inheritance diagram for DataChunker: [legend] Detailed Description Implements a chunked data allocater. Calling new/malloc all the time is a time consuming operation. Therefore, we provide the DataChunker, which allocates memory in blockss of chunkSize (by default 16k, see ChunkSize, though it can be set in the constructor), then doles it out as requested, in chunks of up to chunkSize in size. It will assert if you try to get more than ChunkSize bytes at a time, and it deals with the logic of allocating new blocks and giving out word-aligned chunks. Note that new/free/realloc WILL NOT WORK on memory gotten from the DataChunker. This also only grows (you can call freeBlocks to deallocate and reset things). Public Types enum   { ChunkSize = 16376 } Public Member Functions void *  alloc (S32 size)   Return a pointer to a chunk of memory from a pre-allocated block. void  freeBlocks ()   Free all allocated memory blocks.   DataChunker (S32 size=ChunkSize)   Initialize using blocks of a given size.   ~DataChunker () Private Attributes DataBlock *  curBlock S32  chunkSize Data Structures struct   DataBlock   Block of allocated memory. More... Member Enumeration Documentation anonymous enum Enumerator: ChunkSize  Default size for chunks. Constructor & Destructor Documentation DataChunker::DataChunker ( S32  size = ChunkSize  )  Initialize using blocks of a given size. One new block is allocated at constructor-time. Parameters: size  Size in bytes of the space to allocate for each block. DataChunker::~DataChunker (  )  Member Function Documentation void* DataChunker::alloc ( S32  size  )  Return a pointer to a chunk of memory from a pre-allocated block. This memory goes away when you call freeBlocks. This memory is word-aligned. Parameters: size  Size of chunk to return. This must be less than chunkSize or else an assertion will occur. void DataChunker::freeBlocks (  )  Free all allocated memory blocks. This invalidates all pointers returned from alloc(). Reimplemented in FreeListChunker< T >, FreeListChunker< BufInf >, and FreeListChunker< NetEventNote >.
