Constructor & Destructor Documentation

PolygonBufferChunk (  unsigned short  usType, const NeoEngine::HashString &  rstrType, const NeoEngine::HashString &  rstrID = "" )  [inline]

Initialize chunk Parameters: usType  Chunk type rstrType  Chunk type as string rstrID  Chunk ID string

PolygonBufferChunk (  const NeoEngine::PolygonBufferPtr &  pkBuffer, const NeoEngine::HashString &  rstrID = "", bool  bCreateSubChunk = false )  [inline]

Setup chunk with default values Parameters: pkBuffer  Polygon buffer object rstrID  Chunk ID string, default empty bCreateSubChunk  Create subchunks from polygon buffer object data (num, type) if true

virtual ~PolygonBufferChunk (   )  [inline, virtual]

Deallocate data and subchunks

Member Function Documentation

virtual int GetSize (  bool  bIncludeHeader = false  )  const [virtual]

Get size of chunk in binary mode Parameters: bIncludeHeader  Add header of chunk (type + ID) to size as well as subchunks and data Returns: Size of chunk data in bytes as if read/written from/to file Reimplemented from ComplexChunk.

virtual int ReadData (  NeoEngine::File *  pkFile, ChunkIO::CHUNKIOMODE  eMode, unsigned int  uiEnd )  [virtual]

Read chunk data from file Parameters: pkFile  File eMode  Chunk mode (ChunkIO::ASCII or ChunkIO::BINARY) uiEnd  Bytes to end of chunk (in binary mode) Returns: <0 if error, number of bytes read if successful Reimplemented from Chunk.

virtual int ParseData (  unsigned int  uiFlags, NeoEngine::FileManager *  pkFileManager )  [virtual]

Parse chunk data Parameters: uiFlags  Parse flags pkFileManager  File manager Returns: <0 if error, >0 if successful (0 reserved) Reimplemented from Chunk.

virtual int WriteData (  NeoEngine::File *  pkFile, ChunkIO::CHUNKIOMODE  eMode, unsigned int  uiLevel )  [virtual]

Write chunk data to file Parameters: pkFile  File eMode  Chunk mode (ChunkIO::ASCII or ChunkIO::BINARY) uiLevel  Recursion level for ascii format Returns: <0 if error, number of bytes written if successful Reimplemented from Chunk.

void SetNumChunk (  unsigned int  uiNumElements  )

Set num subchunk Parameters: uiNumElements  Number of elements

void SetTypeChunk (  unsigned int  uiType  )

Set buffer type subchunk Parameters: uiType  Buffer type

Chunk* Allocator (  unsigned short  usType, const NeoEngine::HashString &  rstrType, const NeoEngine::HashString &  rstrID )  [inline, static]

Allocate new chunk Parameters: usType  Type identifier rstrType  Type identifier as string rstrID  ID string Returns: New chunk

virtual bool IsComplex (   )  const [inline, virtual, inherited]

Returns: true (we are a complex chunk) Implements Chunk.

void AttachChunk (  Chunk *  pkChunk, bool  bReplace = false )  [inherited]

Attach subchunk Parameters: pkChunk  Chunk to attach bReplace  Replace and deallocate old chunk of same type and ID (default false)

Chunk* FindChunk (  const NeoEngine::HashString &  rstrID, unsigned short  usType, int  iRecurse = -1, bool  bIgnoreID = false )  [inherited]

Locate chunk in hierarchy matching chunk properties Parameters: rstrID  Chunk ID usType  Chunk type, ignored if zero iRecurse  Recurse on sub (1 - recurse infinite, 0 - only ourselves, -1 only child nodes - default) bIgnoreID  Ignore matching ID string Returns: Ptr to first chunk matching search criteria

int FindChunks (  const NeoEngine::HashString &  rstrID, unsigned short  usType, std::vector< Chunk * > *  pvpkResult, bool  bRecurse = false, bool  bIgnoreID = false )  [inherited]

Find all subchunks matching query Parameters: rstrID  Chunk ID usType  Chunk type, ignored if zero pvpkResult  Vector of chunk pointers receiving pointers to matching subchunks (if null, only count) bRecurse  Recurse on subchunks (default false, search only our subchunks) bIgnoreID  Ignore matching ID string Returns: Number of chunks found

const std::vector< Chunk* >& GetSubChunks (   )  const [inline, inherited]

Returns: Subchunk vector

unsigned short GetType (   )  const [inline, inherited]

Returns: Chunk type

const NeoEngine::HashString& GetTypeAsString (   )  const [inline, inherited]

Returns: Chunk type as string

const NeoEngine::HashString& GetID (   )  const [inline, inherited]

Returns: Chunk ID

int ParseRecursive (  unsigned int  uiFlags, NeoEngine::FileManager *  pkFileManager )  [inherited]

Parse child chunks, then ourselves Parameters: uiFlags  Parse flags pkFileManager  File manager object Returns: <0 if error, >0 if successful (0 reserved for future use)
