Method Detail


public E invokeIndex(int index)
Description copied from class: BaseListCommonStream
Calculate the value at an index.
So it gets the needed input value and call the appropriate invoke function.
Can this be used for a filter call?
The index does not make sense for a filter since you do not know where the input is coming from. So maybe just ignore it.
This is a little messy but less messy that what is there now.

Specified by:
