CDumpContext::operator <<

This operator inserts variables and objects into the dump context.

CDumpContext& operator <<(
LPCTSTR lpsz );

CDumpContext& operator <<(
LPCSTR lpsz );

CDumpContext& operator <<(
LPCWSTR lpsz);

CDumpContext& operator <<(
const void* lp );

CDumpContext& operator <<(
const CObject* pOb );

CDumpContext& operator <<(
const CObject& ob );

CDumpContext& operator <<(
BYTE by );

CDumpContext& operator <<(
WORD w );

CDumpContext& operator <<(
UINT u );

CDumpContext& operator <<(
LONG l );

CDumpContext& operator <<(
DWORD dw );

CDumpContext& operator <<(
float f );

CDumpContext& operator <<(
double d );

CDumpContext& operator <<(
int n ); 

Return Value

A CDumpContext reference. Using the return value, you can write multiple insertions on a single line of source code.

Remarks

The insertion operator is overloaded for CObject pointers as well as for most primitive types. A pointer to character results in a dump of string contents; a pointer to void results in a hexadecimal dump of the address only. A LONGLONG results in a dump of a 64-bit signed integer. A ULONGLONG results in a dump of a 64-bit unsigned integer.

If you use the IMPLEMENT_DYNAMIC or IMPLEMENT_SERIAL macro in the implementation of your class, the insertion operator, through CObject::Dump, prints the name of your CObject-derived class. See RUNTIME_CLASS for information about these macros. Otherwise, it prints CObject. If you override the Dump function of the class, you can provide a more meaningful output of the contents of the object instead of a hexadecimal dump.

Example

// Example for the CDumpContext::operator <<.
extern CObList li;
CString s = "test";
int i = 7;
long lo = 1000000000L;
LONGLONG lolo = 12345678901234i64;
afxDump << "list=" << &li << "string="
  << s << "int=" << i << "long=" << lo << "LONGLONG=" << lolo << "\n";
