These bricks encapsulate n
stops: wait for a sequence of n
signals. wait_until
also traps and untraps the required signals.
wait_n(.trj, n = 1) wait_until(.trj, signals, n = 1)
.trj | the trajectory object. |
---|---|
n | number of |
signals | signal or list of signals, accepts either a string, a list of strings or a callable object (a function) which must return a string or a list of strings. |
wait_n
returns n
times wait
.
wait_until
also adds trap
and
untrap
at the beginning and end, respectively,
of the chain of wait
s (see examples below).
