Hi @Jimmy Christian 

another simpler sample :




XData DTL [ XMLNamespace = "http://www.intersystems.com/dtl" ]
{
<transform sourceClass='formation.RM.personne.Batch' targetClass='common.person' create='new' language='objectscript' >
<foreach property='source.Records()' key='k1' >
<assign value='source.Records.(k1).Nom' property='target.names.(k1)' action='set' />
</foreach>
</transform>
}

Hi @Jimmy Christian,

the syntax in XML is :


XData DTL [ XMLNamespace = "http://www.intersystems.com/dtl" ]
{
<transform sourceClass='formation.RM.personne.Batch' targetClass='formation.msg.mysql.batch' create='new' language='objectscript' >
<foreach property='source.Records()' key='k1' >
<subtransform class='formation.transfo.personne' targetObj='target.list.(k1)' sourceObj='source.Records.(k1)' />
</foreach>
</transform>
}

Use %ConstructClone (from %RegisteredObject)

Method %ConstructClone(deep As %Integer = 0, ByRef cloned As %String, location As %String) as %RegisteredObject

Clone the current object to a new object. If deep is 1 then this does a deep copy which will also copy any subobjects and if deep is 0 then it will create another reference to any subobjects and increment the reference count appropriately. It returns the new cloned object.

Note that even if deep=0 when you clone a parent object in a parent child relationship or a one object of a one to many relationship then it will construct clones of all the child/many objects. This is because a child/many object can only point at a single parent and so if we did not create a clone of these then you would have a relationship with zero items in it. If you really just want to clone the object without these child/many objects then pass deep=-1 to this method.

After the clone is constructed it will call %OnConstructClone(object,deep,.cloned) on the clone if it is defined so that you can perform any additional steps e.g. taking out a lock. This works just the same way as %OnNew() does.

The object is the oref of the original object that was cloned. The cloned array is just used internally when doing a deep clone to prevent recursive loops, do not pass anything in at all for this parameter on the initial call. If you write a %OnConstructClone and from here you wish to call %ConstructClone on another object pass in the cloned array, e.g. 'Do oref.%ConstructClone(1,.cloned)' so that it can prevent recursive loops.

The location is used internally to pass the new location for stream objects.
