CDXVec Overloaded Operators
The functions in this section enable you to perform mathematical operations with CDXVec class objects.
operator [] ( int index ) Accesses a dimension of the structure by index as an integer. operator [] ( long index ) Accesses a dimension of the structure by index as a long. operator [] ( USHORT index ) Accesses a dimension of the structure by index as a USHORT. operator [] ( DWORD index ) Accesses a dimension of the structure by index as a DWORD. operator = Assigns components of one vector to another vector. operator != Tests for inequality of two vectors. operator + Adds two vectors, returning a resultant vector. operator - Subtracts two vectors, returning a resultant vector. operator += Increments a vector with another vector. operator -= Decrements a vector with another vector. operator == Tests for equality of two vectors. ZeroVector Sets all components of a vector to zero.
CDXVec::operator [] ( int index )

CDXVec::operator [] ( long index )
Accesses a dimension of the structure by index.
Syntax
TYPE& operator[]( long index ) const;
Parameters
- index
- Long value used to access a dimension of the structure.
Return Value
Returns a TYPE& reference.
CDXVec::operator [] ( USHORT index )
Accesses a dimension of the structure by index.
Syntax
TYPE& operator[]( USHORT index ) const;
Parameters
- index
- USHORT value used to access a dimension of the structure.
Return Value

CDXVec::operator [] ( DWORD index )
Accesses a dimension of the structure by index.
Syntax
TYPE& operator[]( DWORD index ) const;
Parameters
- index
- DWORD value used to access a dimension of the structure.
Return Value

Return Value
Returns a CDXV_C result.
CDXVec::operator +=
Increments a vector with another vector.
Syntax
void operator+=( const CDXV_C &vOther );
Parameters
- vOther
- Vector passed in to be added.
Return Value
No return value.
CDXVec::operator -=
Decrements a vector with another vector.
Syntax
void operator-=( const CDXV_C &vOther );
Parameters
- vOther
- Vector passed in to be subtracted.
