The Indecore SDK documentation for writing an indicator refers to a set of mandatory functions the second of which is the Prepare() function.
The document refers to a global variable called instance which is hyperlinked see screenshot. The hyperlink points to the structure of this global variable which is in the form of a table with various properties and methods associated with it. I assume that an instance of this table can be considered an object.
Why does the documentation for the table describing this global variable structure have the suffix _impl?
Does _impl have some meaning?
Thanks for any reply
