ReferenceEquals()

OutputVar := MfObject.ReferenceEquals(objA, objB)

ReferenceEquals(objA, objB)

Determines whether the specified Object instances are the same instance.

Parameters

objA

The first object to compare.

objB

The second object to compare.

Returns

Returns true if objA is the same instance as objB or if both are null; Otherwise, false.

Remarks

If you want to test two object references for equality and are unsure about the implementation of the Equals method, you can call the ReferenceEquals method. When calling this method call using MfObject.ReferenceEquals to ensure that ReferenceEquals has not been overridden on Derived classes.
Static Function.

Example

o := MfNull.Null
p := MfNull.Null
q := Object()
MsgBox % MfObject.ReferenceEquals(o, p) ; displays 1 for true
MsgBox % MfObject.ReferenceEquals(p, q) ; displays 0 for false
