occ sample geometry 分析初探2

occ 中的内存管理，也可以采取地址的方式来传引用。

//Here I commit a stupid error

//I define a reference in the header file 

//But I define another name in the source code

//the pArray change to the array so bu la bu la

cause this error :

error C2248: 'TColgp_Array1OfPnt::TColgp_Array1OfPnt' : cannot access private member declared in class 'TColgp_Array1OfPnt'

//in the header file

	 static int datatrim(TColgp_Array1OfPnt & pArrayAfterTrim, TColgp_Array1OfPnt rawArray, int trimStep,Standard_Real Tolerance = 1);

//in the source code

int GeomSources::trimRawData( TColgp_Array1OfPnt & arrayAfterTrim, TColgp_Array1OfPnt rawArray, int trimStep, Standard_Real Tolerance/* = 8*/ )
{
	....
	
}

//even this i commit another error to 
I try do the deep copy in the 
 TColgp_Array1OfPnt rawArray
How stupid I was!!!
