示例1: InternReadFile

void AssbinImporter::InternReadFile( const std::string& pFile, aiScene* pScene, IOSystem* pIOHandler )
{
    IOStream * stream = pIOHandler->Open(pFile,"rb");
    if (!stream)
        return;

    stream->Seek( 44, aiOrigin_CUR ); // signature

    /*unsigned int versionMajor =*/ Read<unsigned int>(stream);
    /*unsigned int versionMinor =*/ Read<unsigned int>(stream);
    /*unsigned int versionRevision =*/ Read<unsigned int>(stream);
    /*unsigned int compileFlags =*/ Read<unsigned int>(stream);

    shortened = Read<uint16_t>(stream) > 0;
    compressed = Read<uint16_t>(stream) > 0;

    if (shortened)
        throw DeadlyImportError( "Shortened binaries are not supported!" );

    stream->Seek( 256, aiOrigin_CUR ); // original filename
    stream->Seek( 128, aiOrigin_CUR ); // options
    stream->Seek( 64, aiOrigin_CUR ); // padding

    if (compressed)
    {
        uLongf uncompressedSize = Read<uint32_t>(stream);
        uLongf compressedSize = stream->FileSize() - stream->Tell();

        unsigned char * compressedData = new unsigned char[ compressedSize ];
        stream->Read( compressedData, 1, compressedSize );

        unsigned char * uncompressedData = new unsigned char[ uncompressedSize ];

        uncompress( uncompressedData, &uncompressedSize, compressedData, compressedSize );

        MemoryIOStream io( uncompressedData, uncompressedSize );

        ReadBinaryScene(&io,pScene);

        delete[] uncompressedData;
        delete[] compressedData;
    }
    else
    {
        ReadBinaryScene(stream,pScene);
    }

    pIOHandler->Close(stream);
}
