expyriment.misc.ByteBuffer¶

class expyriment.misc.ByteBuffer(name='ByteBuffer', clock=None)¶

A class implementing a buffer for bytes.

The ByteBuffer class is also used for the input_histoy of serial and parallel ports.

__init__(name='ByteBuffer', clock=None)¶

Create a buffer for bytes.

Parameters:	namestr the name of the buffer clockexpyriment.Clock object (optional) an experimental clock

add_event(event)¶

Add an event to the buffer.

Parameters:	eventanything the event to add

add_events(events)¶

Add a list of events to the buffer.

All events get the same time stamp!

Parameters:	eventslist the event list to add

check_set(search_byte, search_start_position=0)¶

Check if bits are set in buffer bytes and return position.

Parameters:	search_byteint the byte to search for search_start_positionint (optional) position to start search from (int)
Returns:	positionint the position of element with set bits

check_unset(search_byte, search_start_position=0)¶

Check if bits are NOT set in buffer bytes and return position.

Parameters:	search_byteint the byte to search for search_start_positionint (optional) position to start search from
Returns:	positionint the position of element with unset bits

check_value(value, search_start_position=0)¶

Check if value is in buffer bytes and return the position.

Parameters:	valueint the value to check search_start_positionint (optional) position to start search from
Returns:	positionint the position of element with value

get_element(position)¶

Get an element (code, rt) from the buffer.

Parameters:	positionint the position to get the element from
Returns:	element(anything, float) The element to get from the buffer

get_last_event()¶

Get the last event (code, rt) in the buffer.

Returns:	element(anything, float) the last element of the buffer

get_size()¶

Return the number of elements in the buffer.

Returns:	sizeint the size of the buffer

get_whole_buffer()¶

Get a copy of the buffer.

Returns:	copylist the copy of the buffer
