Public Functions
-
TrialSelectParticle
(const argtype &args = argtype())¶ args:
load_coordinates: load the coordinates into the selection (default: true)
site: site index to select. If all sites, set to -1 (default).
ghost: select ghost particles (default: false).
exclude_perturbed: if true, exclude perturbed particle (default: false)
-
bool
load_coordinates
() const¶ Return true if loading coordinates into selection.
-
int

() const¶ Return site.
-
int
random_particle
(const Configuration &config, const Select *exclude, Select *select, Random *random)¶ - Parameters
exclude
: Exclude from selection.
Add random particle in group index to select. Return the number of particles to choose from.
-
int
random_particle
(const Configuration &config, Select *select, Random *random)¶ Same as above, but no exclusions.
-
void
ghost_particle
(Configuration *config, const Select *exclude, Select *select)¶ Select a ghost particle.
- Parameters
exclude
: Exclude from selection.
-
void
ghost_particle
(Configuration *config, Select *select)¶ Same as above, but no exclusions.
-
bool
select
(const Select &perturbed, System *system, Random *random)¶ - Parameters
perturbed
: Perturbed is included to allow chaining of selection based on previous.
Perform the selection as implemented in the derived class. Return false if the selection cannot be made. Otherwise, return true.
