What I do not understand is the : “UINT&”. What does it mean in the context of the template
static CMap<CString, LPCSTR, UINT, UINT&> cXMLfields::fields_by_name;
static CMap<CString, LPCSTR, UINT, UINT&> cXMLfields::oopf_fields_by_name;
static CString friendly_name[XML_FIELDNUM];
static CString fields_by_id[XML_FIELDNUM];
static CString oopf_fields_by_id[OOPF_XML_FIELDNUM];
static void Build_map();
static void MoveItem(CListBox& src, CListBox& dst, int index);
CMap<CString,LPCTSTR, struct_sample,struct_sample> myMap;
struct_sample aTest;
aTest.a = 1;
aTest.b = 2;
aTest.c = 3;
myMap.SetAt("test",aTest);
struct_sample aLookupTest;
BOOL bExists = myMap.Lookup("test",aLookupTest); //Retrieves the
//struct_sample corresponding to "test".
我理解这个理论,但我的密钥是一个字符串,例如“RFIDTAG1”。我的值是无符号整数。 Example.UNIT是特定KEY的值...例如{Age:27}其中Age是Key而27是Value.I当值是一个整数时,我会理解这个值是否是一个结构。那么您可以使用{年龄:27}作为示例,并在使用结构时向我显示如下代码
