pint.toa_select.TOASelect

class pint.toa_select.TOASelect(is_range, use_hash=False)

Bases: object

Select toas from toa table based on a given condition.

The selection result will be saved in the select_result attribute as a mini caching for the future calculation.

Parameters:

• is_range (bool) – Is this toa selection a range selection.

• use_hash (bool, optional [default: False]) – If use hash for caching.

Note

The supported condition types are:

• Ranged condition in the format of {‘DMX_0001’:(54000, 54001), …}

• Key condition in the format of {‘JUMP1’: ‘L-wide’, …}

Putting an object as condition will slow the process dramatically.
