Purpose
Get the size of
an array, set, list, constraint or string.
Synopsis
function getsize(a:array):integer
function getsize(s:set):integer
function getsize(l:list):integer
function getsize(t:string):integer
function getsize(c:linctr):integer
Arguments
a

An array

s

A set

l

A list

t

A string

c

A linear constraint

Return value
Number of effective entries for an array, number of elements for a set or a list, number of characters for a string, number
of terms for a constraint.
Example
In the following, a dynamic array is declared holding eight elements, of which only two are actually defined. Calling getsize on this array returns 2 rather than 8. The length lw of the string w is 9.
declarations
a:dynamic array(1..8) of real
w = "some text"
enddeclarations
a(1):= 4
a(5):= 7.2
la:= getsize(a)
lw:= getsize(w)
Further information
In the
case of a dynamic array that has been declared with a maximal range
this number may be smaller than the size of the range, but it cannot
exceed it. When used with a string, this function returns the length
of the string (i.e. the number of characters it contains).
If used with a linear constraint, this function returns the number
of terms of the constraint (the constant term is not taken into
account).
