The easiest way to create a deep copy of an existing object (as opposed
to just a pointer to the original object) is to leverage the fact that
by default parameters are passed by value in Visual Foxpro. So to make
an copy:
* -- CODE START
* -- Your original object.
loMyObject = CreateObject("MyObject")
loMyObject.Property1="hello"
* -- A new instance to hold the copy.
loMyCopy = CreateObject("MyObject")
loMycopy = DoCopy(loMyCopy)
* -- Make an copy.
Function DoCopy(loObjectIn as Object)
Return loObjectIn
* -- CODE END
So then:
? loMyObject.Property1 yields "hello"
? loMyCopy.Property1 yields "hello"
loMyCopy.Property1 = "bonjour"
? loMyObject.Property1 yields "hello"
? loMyCopy.Property1 yields "bonjour"
