Function Details

[hide private]

build_segment_list(engine, gps_start_time, gps_end_time, ifo, segment_name, version=None, start_pad=0, end_pad=0)

source code

Optains a list of segments for the given ifo, name and version between the specified times. If a version is given the request is straightforward and is passed on to build_segment_list_one. Otherwise more complex processing is performed (not yet implemented)

ensure_segment_table(connection)

source code

Ensures that the DB represented by connection posses a segment table. If not, creates one and prints a warning to stderr

run_query_segments(doc, proc_id, engine, gps_start_time, gps_end_time, included_segments_string, excluded_segments_string=None, write_segments=True, start_pad=0, end_pad=0)

source code

Runs a segment query. This was originally part of ligolw_query_segments, but now is also used by ligolw_segments_from_cats.

The write_segments option is provided so callers can coalesce segments obtained over sever invocations (as segments_from_cats does).
