The module ExtractObjectFromList extracts objects from a list derived from ml::BaseList (for example a XMarkerList) identifying them via search parameters (currently only the index in the list).
Its functionality is sort of similar to DecomposeBaseList, but the lists the ExtractObjectFromList module can handle hold only objects of the same type.
Connect an object derived from ml::BaseList to the input and specify search parameters for the object you want to extract. Verify that the output is valid and connect the output to the operator where the object is needed.
The module has one base input that must be connected to a valid object derived from ml::BaseList. If the input object has an incorrect type, the fied Input List Valid will be unchecked and the module will not work.
The module has one output holding the extracted object.
Sets a positive integer k to obtain the element at position k in the filtered list (starting with 1!). Enter a negative integer -k to obtain the element at position (sizeOfInputList - k + 1).
For example, to always obtain the last element of the input list, you have to specify -1 here.
Shows the number of items in the input list.
