Clone variable

Anatomy

<clone var="var" var_result="(same as 'var')"/>

Description: CLONE creates a shallow copy of the value of a variable independent of it's data type.

If the result variable 'var_result' is omitted, the resulting value will be stored in 'var' instead.

Attention:

CLONE preserves all meta information associated with the original variable including the class information of an object.
