qlat.FieldSelection

class qlat.FieldSelection(*args)

__init__()

FieldSelection() FieldSelection(geo, 0) # selecting all points FieldSelection(geo, -1) # no points being selected FieldSelection(geo) # same as FieldSelection(geo, -1), no points being selected FieldSelection(psel) # require psel.points_dist_type in [ “l”, “f”, “g”, ] FieldSelection(psel, geo) # require psel.points_dist_type in [ “l”, “f”, “g”, ]

Methods

__init__	FieldSelection() FieldSelection(geo, 0) # selecting all points FieldSelection(geo, -1) # no points being selected FieldSelection(geo) # same as FieldSelection(geo, -1), no points being selected FieldSelection(psel) # require psel.points_dist_type in [ "l", "f", "g", ] FieldSelection(psel, geo) # require psel.points_dist_type in [ "l", "f", "g", ]
add_fsel(self, FieldSelection fsel)	Add fsel points to the selection, with the rank specified in fsel.
add_psel(self, PointsSelection psel, ...)	Add psel points to the selection, with the rank specified as rank_psel.
coordinate_from_idx(self, Long idx)
copy(self)
idx_from_coordinate(self, Coordinate xg)
init_from_geo(self, Geometry geo, Long rank=-1)	By default rank=-1 means empty selection.
init_from_psel(self, PointsSelection psel, ...)	psel.points_dist_type [ "g", "f", "l", ]
intersect(self, FieldSelection fsel)	Do NOT change the self, but return a new one More efficient if self is smaller than fsel
intersect_with(self, FieldSelection fsel)	Modify the self.
is_containing(self, sel_small)
is_containing_fsel(self, ...)
is_containing_psel(self, ...)
load(self, string path)
release_buffer(self, Buffer buf)
save(self, string path)
set_empty(self, Geometry geo)	set an empty fsel with geo (all rank=-1)
set_rand(self, Coordinate total_site, ...)
set_rand_psel(self, Coordinate total_site, ...)
set_uniform(self, Geometry geo, Long val=0)	default (val = 0) select every sites val = -1 deselection everything
to_psel(self)
to_psel_local(self)
update(self)	update various indices based on f_rank
