B4J Question how to know their class type

jinyistudio · Jun 9, 2016

Hi

I have two class as following

B4X:

dim class1 as jyMbSerial
dim class2 as jyMbTcp

And i pass them to following function

B4X:

publice sub Setinterface(intf as object)
        :
end sub

SetInterface(class1)  Or SetInterface(class2)

In SetInterface,How to check intf is jyMbSerial Or jyMbTcp ??

You can implement SetInterface in each of these classes and then call it with:

B4X:

CallSub(YourObject, "SetInterface")

If you do want to check for the class type then you can use:

B4X:

If class1 Is jyMbSerial Then
 Dim m As jyMbSerial = class1
 ...
