New in version 2.0.
Replace contents of target_container with contents of source_container:
abjad> staff = Staff(Tuplet(Fraction(2, 3), "c'8 d'8 e'8") * 3)
abjad> pitchtools.set_ascending_named_diatonic_pitches_on_nontied_pitched_components_in_expr(staff)
abjad> spannertools.BeamSpanner(staff.leaves)
BeamSpanner(c'8, d'8, ... [5] ..., c''8, d''8)
abjad> f(staff)
\new Staff {
\times 2/3 {
c'8 [
d'8
e'8
}
\times 2/3 {
f'8
g'8
a'8
}
\times 2/3 {
b'8
c''8
d''8 ]
}
}
abjad> container = Container("c'8 d'8 e'8")
abjad> spannertools.SlurSpanner(container.leaves)
SlurSpanner(c'8, d'8, e'8)
abjad> f(container)
{
c'8 (
d'8
e'8 )
}
abjad> containertools.replace_contents_of_target_container_with_contents_of_source_container(staff[1], container)
Tuplet(2/3, [c'8, d'8, e'8])
abjad> f(staff)
\new Staff {
\times 2/3 {
c'8 [
d'8
e'8
}
\times 2/3 {
c'8 (
d'8
e'8 )
}
\times 2/3 {
b'8
c''8
d''8 ]
}
}
Leave source_container empty:
abjad> container
{}
Return target_container.
