-
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: name : str
the name of the buffer
clock : expyriment.Clock object (optional)
an experimental clock
-
add_event(event)¶ Add an event to the buffer.
Parameters: event : anything
the event to add
-
add_events(events)¶ Add a list of events to the buffer.
All events get the same time stamp!
Parameters: events : list
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_byte : int
the byte to search for
search_start_position : int (optional)
position to start search from (int)
Returns: position : int
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_byte : int
the byte to search for
search_start_position : int (optional)
position to start search from
Returns: position : int
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: value : int
the value to check
search_start_position : int (optional)
position to start search from
Returns: position : int
the position of element with value
-
clear()¶ Clear the buffer.
-
clock¶ Getter for clock
-
get_element(position)¶ Get an element (code, rt) from the buffer.
Parameters: position : int
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: size : int
the size of the buffer
-
get_whole_buffer()¶ Get a copy of the buffer.
Returns: copy : list
the copy of the buffer
-
memory¶ Getter for memory [list of tuples (code, rt)]
-
name¶ Getter for name
