Equality Operator (AnnPoint)

Visual Basic
C#
Objective-C
Java
C++

public bool operator ==( 
   AnnPoint left,
   AnnPoint right
)

'Declaration
 
Public Operator =( _
   ByVal left As AnnPoint, _
   ByVal right As AnnPoint _
) As Boolean

'Usage

public:
bool operator ==( 
   AnnPoint left,
   AnnPoint right
)

Parameters

left: The AnnPoint structure on the left side of the equality operator.
right: The AnnPoint structure on the right side of the equality operator.

Return Value

This operator returns true if left and right have equal X and Y values; otherwise false.

If the two points have different units, the comparison will be done after temporarily converting both to a common unit.
