DELETE_

#define DELETE_

(

OBJ

)

Value:

{ \
    if( OBJ ) {delete OBJ; OBJ = NULL;} \
}

Macro for safe deleteing the object and sets the pointer to zero.

Parameters

OBJ	- pointer to the object

DELETE_TAB

#define DELETE_TAB

(

OBJ

)

Value:

{ \
    if( OBJ ) std::cerr << " Delete tab: " << #OBJ << " address = " << OBJ << std::endl; \
    if( OBJ ) {delete [] OBJ; OBJ = NULL;} \
}

Macro for safe deleteing the array and sets the pointer to zero.

Parameters

OBJ	- pointer to the array

NEW_TAB

#define NEW_TAB	(		Var,
			Typ,
			Len )

Value:

{ \
    (Var) = new Typ[Len]; \
    std::cerr << " Creating object: " << #Var << " address = " << Var << " typ: " << #Typ << " size (type units) = " << Len << std::endl; \
    memset( (Var), 0, sizeof(Typ)*(Len) ); \
}

Macro for initializing array with zeros.

Parameters

Var	- pointer to the array
Typ	- type of array (e.g. double)
Len	- legth of array

Definition at line 71 of file memfun.h.

#define NEW_TAB( Var, Typ, Len ) \
{ \
    (Var) = new Typ[Len]; \
    std::cerr << " Creating object: " << #Var << " address = " << Var << " typ: " << #Typ << " size (type units) = " << Len << std::endl; \
    memset( (Var), 0, sizeof(Typ)*(Len) ); \

Function Documentation

ERASE()

template<class typ >

void ERASE	(	typ **	ptr,
		const char *	text = "(No name specified)" )

Safe erasing of the object and sets the pointer to zero.

Parameters

ptr	- reference to the object pointer
text	- optional comment to be printed to stderr

      //std::cerr << "Delete performed ptr " << (int)*ptr << text << std::endl;
      delete *ptr;
      *ptr = NULL;
      }
    else
      std::cerr << "Warning! Pointer to : " << text << " is NULL !!! No delete performed" << std::endl;
