Array Basics

Returns the number of elements in an array.

Creates an array of the specified size with all elements initialized to the specified value.

Extracts a single element from an array at the specified index; returns NIL if the index is out of range.

Extracts a single element from an array at the specified index; returns NIL if the index is out of range.

Extracts up to 8 individual elements from an array or NIL for indices out of range.

Get random array elements with repeating values or not.

Sets an element of an array to a new value.

Tests whether the size of an array equals zero.

Tests whether the size of an array equals the given value.

Tests whether an array contains Nil elements.

Tests whether an array does not contain Nil elements.

Finds first location of a given value in the input array.

If the input array contains no Nil values, then it is copied to the output; otherwise Nil is returned.

Changes an array with conditional elements into a conditional array. Can be useful if some processing should be performed only when all expected objects are correctly detected.

If the input array is short enough, then it is copied to the output; otherwise Nil is returned.

Secures against domain errors caused by arrays having too many elements.

If the input array has enough elements, then it is copied to the output; otherwise Nil is returned.

Secures against domain errors caused by arrays having too few elements, e.g. just before the FitSegmentToPoints filter is to be invoked.
