SegmentPointer#

class iqm.pulse.scheduler.SegmentPointer(source, idx, TOL, frac=0.0)#

Tool for working with Segments.

Serves as a time pointer inside the Segment.

Attributes

`frac`	time, in seconds, after the start of the current instruction
`remainder`	Remaining duration of the current instruction (in seconds).
`source`	contents of the Segment
`idx`	index of the current instruction
`TOL`	time durations equal or smaller than this tolerance are considered zero (in seconds)

Methods

`cut_tail`	Cut the source of the pointer at the current index.
`fastforward`	Move the pointer forward by `duration` seconds.
`get`	Current instruction.
`next`	Move to the beginning of the next instruction.
`rewind`	Move the pointer back by `duration` seconds.
`tail`	Instructions from the current index onwards.

Parameters:

TOL: float#: time durations equal or smaller than this tolerance are considered zero (in seconds)

frac: float = 0.0#: time, in seconds, after the start of the current instruction

get()#

Current instruction.

property remainder: float#: Remaining duration of the current instruction (in seconds).

next()#

Move to the beginning of the next instruction.

cut_tail()#

Cut the source of the pointer at the current index.

Truncate source at idx, make self point to the cut tail part only. frac is not changed.

Note: modifies source.

tail()#

Instructions from the current index onwards.

rewind(duration)#

Move the pointer back by duration seconds.

fastforward(duration)#

Move the pointer forward by duration seconds.
