get_constraints_number(?Var, -Number)

   Returns the number of propagators attached to the gecode variable representing Var.

Arguments
   Var                 A domain variable or a term
   Number              Variable (instantiates to a non-negative integer)

Type
   library(gfd)

Description

   Returns the number of propagators attached to the gecode variable
   representing Var, This approximates the number of constraints attach
   to the variables, and is known as the degree of the variable in the
   literature. 

   If Var is not a variable, a very large number (1.0Inf) is returned. If
   Var is a variable but not a domain variable, 0 will be returned.

   Note that unlike a native ECLiPSe solver like IC, this is not the number 
   of suspensions on the variable, but is the number of propagators
   attached to the Gecode variable, obtained via the degree() method
   for IntVar. Thus, any constraints implemented at the ECLiPSe level
   will not be included in this count.
