sievetools.ResidueClassExpression

class abjad.tools.sievetools.ResidueClassExpression.ResidueClassExpression.ResidueClassExpression(rcs, operator='or')

Read-only Properties

ResidueClassExpression.operator

Operator of residue class expression.

ResidueClassExpression.period

ResidueClassExpression.rcs

Residue classes of expression.

ResidueClassExpression.representative_boolean_train

ResidueClassExpression.representative_congruent_bases

Methods

ResidueClassExpression.get_boolean_train(*min_max)

Returns a boolean train with 0s mapped to the integers that are not congruent bases of the RC expression and 1s mapped to those that are. The method takes one or two integer arguments. If only one is given, it is taken as the max range and min is assumed to be 0.

Example:

abjad> from abjad.tools.sievetools import ResidueClass as RC

abjad> e = RC(3, 0) | RC(2, 0)
abjad> e.get_boolean_train(6)
[1, 0, 1, 1, 1, 0]
abjad> e.get_congruent_bases(-6, 6)
[-6, -4, -3, -2, 0, 2, 3, 4, 6]

Return list.

ResidueClassExpression.get_congruent_bases(*min_max)

Returns all the congruent bases of this RC expression within the given range. The method takes one or two integer arguments. If only one it given, it is taken as the max range and min is assumed to be 0.

Example:

abjad> from abjad.tools.sievetools import ResidueClass as RC

abjad> e = RC(3, 0) | RC(2, 0)
abjad> e.get_congruent_bases(6)
[0, 2, 3, 4, 6]
abjad> e.get_congruent_bases(-6, 6)
[-6, -4, -3, -2, 0, 2, 3, 4, 6]

Return list.
