Detailed Description

Here is an example using this container to restrain all particles in a set to be within a a certain distance of one another.

## \example core/restrain_diameter.py
## An example restraining the diameter of a set of points. That is, the restraint penalizes conformations where there are two point more than a certain distance from one another.

import IMP
import IMP.core
import IMP.container

# This example restraints the diameter of a set of particles to be smaller than 10

diameter=10
m= IMP.Model()
lc= IMP.container.ListSingletonContainer(IMP.core.create_xyzr_particles(m, 50, 1.0))
h=IMP.core.HarmonicUpperBound(0,1)
r=IMP.core.DiameterRestraint(h, lc, diameter)
m.add_restraint(r)

# Set up optimizer
o= IMP.core.ConjugateGradients()
o.set_model(m)

max=0
for p0 in lc.get_particles():
    for p1 in lc.get_particles():
        d=IMP.core.get_distance(IMP.core.XYZ(p0),
                            IMP.core.XYZ(p1))
        if d > max: max=d
print "The maximim distance is "+str(max)

IMP.base.set_log_level(IMP.base.SILENT)
o.optimize(100)

max=0
for p0 in lc.get_particles():
    for p1 in lc.get_particles():
        d=IMP.core.get_distance(IMP.core.XYZ(p0),
                            IMP.core.XYZ(p1))
        if d > max: max=d
print "Afterwards, the maximim distance is "+str(max)
Note
Sequential access is much more efficient than random access which is suicidally slow for now. Complain if you want fast(er) random access. We might listen.
The maintenance of the invariant is done by an associated IMP::Constraint. As a result, the state is only guaranteed to be correct either during model evaluation, or immediately following model evaluation before any particles have been changed.
