# Gecode::Int::GCC::HallInfo Class Reference

## Detailed Description

Container class provding information about the Hall structure of the problem variables.This class is used to keep the number of different arrays small, that is an array of type HallInfo replaces integer arrays for each of the class members.

difference between critical capacities

d_i is the difference between the capacities of hall[i].bounds and its predecessor in bounds hall[t[i]].bounds

Definition at line 557 of file gccbndsup.icc.

Hall set pointer.

If hall[i].h < i then the half-open interval [hall[h[i]].bounds,hall[i].bounds) is containd in a Hall set. Otherwise holds a pointer to the Hall intervall it belongs to.

Bound update.

*newBound* contains either a narrowed domain bound or is stores the old domain bound of a variable.
