示例1: ConstructionDataBlock
void Package::ConstructionDataBlock(DataSource &Source,unsigned long ConstructionPosition)
{
int BlockCount = Source.GetBlockCount();
int CurrentPoint = ConstructionPosition;
/* Interval Interval1;
Interval1.StartRecord ();
*/
for( int i=0; i<BlockCount; i++)
{
DataPointFromStream FilePoint(m_DataStream,CurrentPoint);
BlockSource Block(FilePoint);
// Interval Interval2;
// Interval2.StartRecord ();
Block.CloneBlockSourceToMe(Source[i]) ;
// Interval2.EndRecord();
// cout <<"部分耗时"<<(Interval2.GetInterval() )<<endl;
m_DataBlock.InsertBlock(Block);
CurrentPoint = CurrentPoint + Block.GetLength();
}
// Interval1.EndRecord();
// cout <<"总循环耗时"<<(Interval1.GetInterval() )<<endl;
