list.empty()

list.empty

This returns a Boolean depending on whether the List- or Set-type list is empty. If empty, the return value is true, if the attribute has content then false is returned.

$MyList = [hello;world]; $MyBoolean = $MyList.empty;

$MyBoolean is set to false as content is found. But

$MyList = []; $MyBoolean = $MyList.empty;

$MyBoolean is set to true as no content is found.
