class pswamp.utils.time_window.TimeWindow(n_samples=100, n_cols=0, dtype=float)

Stores the most recent n_samples of multichannel data, and corresponding time stamps. Updating with a new set of measurements is efficient, since only one row in the data array (self._data) is overwritten.

n_samples = 100

n_cols = 0

n_channels = 0

_time

_k = 0

get_safe(col_idx=slice(None))

get(col_idx=slice(None))

Get time vector and data array. If col_idx is specified, only the corresponding columns are returned. If not specified, all columns are returned.

Parameters:: col_idx – Indices of data columns to be returned.
Returns:: Time vector and data array.

get_time(): Get time vector. :returns: Time vector.

get_col(col_idx=slice(None))

Get data columns. If col_idx is specified, only the corresponding columns are returned. If not specified, all columns are returned. :param col_idx: Indices of data columns to be returned.

Returns:: Data array.

append(new_time, new_data): Append a new set of measurement data, and corresopnding time stap. :param new_time: Time stamp. Single number. :param new_data: Row of measurement data.

append_data(new_data): Append a new set of measurement data, without time stamp. :param new_data: Row of measurement data.

class pswamp.utils.time_window.GrowingTimeWindow(n_samples=None, n_cols=0, dtype=float)

Bases: TimeWindow

Stores the most recent n_samples of multichannel data, and corresponding time stamps. Updating with a new set of measurements is efficient, since only one row in the data array (self._data) is overwritten.

Returns:: Data array.

append(new_time, new_data)

Append a new set of measurement data, and corresponding time stap. :param new_time: Time stamp. Single number. :param new_data: Row of measurement data.
