difference between exists and createIf

[Former Member]

Hi all,

In Node functions we are having createIf and exists. what is the difference between createIf and exists? Where we have to use createIf and where we have to use exists?

Thanks

Hi Sridhar

Source Node --- Exists ---target Node ..... this says that the target node will be created if and only if the source node (may be source occurences is 0...1)through which you are mapping exists or not.. If it than target node will be created if not than it wont be created ...

Source node -

---

creatIf---target Node ...... this says that there will be some condition in source side ...if that condition is true than create the target node otherwise do not create

source -

exists -

target

If there is a name node in source than only create the name node in target else not.

Its a very simple example i am giving which can moulded into any complex situations ...

Hope you got it else send me a sample source structure I will explain it with that.

Hi Sridhar,

CreateIf function has input a boolean value of true or false and its output is a target node.....to be created or not based on the input value........

Exists function has input a source node and outputs a boolean value of true or false depending whter the source node is present in source file or not....
