Another Class Question - Passing an optional parameter

HCL Domino Domino Forum

How do I set up my user defined class to accept an optional parameter. I have a class mails a to a predefined mailbox. I’d like to be able to override that for testing by passing in a string of a different email address. Such as:

Sub send( strOtherEmail as string )

if strOtherEmail <> “” then me.m_sendTo = strOtherEmail

call me.mailDoc.send()

End sub

strOtherEmail should be an optional parameter to send(). But as written, lotusScript always wants a parameter there.

Thanks for the help.

Hi Jeff,

You can’t directly code optional parameters in your own subs and functions.

Your technique of checking strOtherMail = “” is one way to do what you want.

Another possibility would be to subclass your original class and override the send method such that your subclass simply ignores the strOtherEmail parameter. Something like this:

Class Mail

Sub send( sendTo As String )

	

End Sub

End Class

Class TestMail As Mail

Sub send( sendTo As String )

	

	Mail..send( "Joe Bloggs" )

	

End Sub

End Class
