Name

tuple_select_rangetuple_select_rangetuple_select_rangeTupleSelectRangeTupleSelectRange — Select several elements of a tuple.

Signature

Description

tuple_select_rangetuple_select_rangetuple_select_rangeTupleSelectRangeTupleSelectRange selects several consecutive elements of the input tuple TupleTupleTupleTupletuple and returns them with SelectedSelectedSelectedSelectedselected. At this, LeftindexLeftindexLeftindexLeftindexleftindex determines the index of the first element and RightindexRightindexRightindexRightindexrightindex determines the index of the last element to select. Thus both parameters LeftindexLeftindexLeftindexLeftindexleftindex and RightindexRightindexRightindexRightindexrightindex must contain a single integer value (any floating point number must represent an integer value without fraction). Indices of tuple elements start at 0, that means, the first tuple element has got the index 0. The result tuple SelectedSelectedSelectedSelectedselected contains every element from the tuple TupleTupleTupleTupletuple that has got an index between LeftindexLeftindexLeftindexLeftindexleftindex and RightindexRightindexRightindexRightindexrightindex (including the elements at position LeftindexLeftindexLeftindexLeftindexleftindex and RightindexRightindexRightindexRightindexrightindex). If the indices are equal, only one element is selected. In addition, it is possible that the right index is LeftindexLeftindexLeftindexLeftindexleftindex - 1. In this case and if the left or right index are valid an empty tuple is returned. Hence, the index RightindexRightindexRightindexRightindexrightindex must be greater or equal to LeftindexLeftindexLeftindexLeftindexleftindex - 1.

Parallelization

• Multithreading type: independent (runs in parallel even with exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.
