                                int size)

Description copied from class: ScriptArray

This method grows the array by adding more elements of a given size. An offset parameter can be used to specify where the new elements have to be added (starting from zero). The operation is equivalent to shifting (right) the whole array or its part as defined by the offset parameter.

Specified by:

addRangeImpl in class ScriptArray

offset - starting offset position

size - size of the inserted empty array

Returns:

a ScriptArray instance with the new size
