Availability

This routine is available starting with SIL Engine™ 1.0.

Description

If elem is an element of the array type, returns a new array without the specified element.

Alias

deleteElement(arrayName, elem)

Parameters

Parameter name	Type	Required	Description
arrayName	array	Yes	Array the new element is deleted from.
elem	any	Yes	Element to be deleted. Must be the same type as the array type.

Return Type

array

Example

watchers = deleteElement(watchers, currentUser());

The result returned by the routine is assigned to the the same array watchers, so the initial array watchers will be modified.

Notes

If array is not defined as an array, the routine returns error.
If elem is not the same type as declared in the array definition, the routine returns error.

SIL Engine™ 2.5 specific

Starting with version 2.5, there is a more powerful way to express these operations: array = array - element; or even better array -= element;
