Package topo :: Package sheet :: Module basic :: Class SequenceGeneratorSheet

Class SequenceGeneratorSheet

Sheet that generates a timed sequence of patterns.

This sheet will repeatedly generate the input_sequence, with the given onsets. The sequence is repeated every self.period time units. If the total length of the sequence is longer than self.period, a warning is issued and the sequence repeats immediately after completion.

Method Details

[hide private]

init(self, **params)
(Constructor)

source code

x.__init__(...) initializes x; see x.__class__.__doc__ for signature

Overrides: object.__init__: (inherited documentation)

start(self)

source code

Called by the simulation when the EventProcessor is added to the simulation.

If an EventProcessor needs to have any code run when it is added to the simulation, the code can be put into this method in the subclass.

Overrides: base.simulation.EventProcessor.start: (inherited documentation)

Class Variable Details

input_sequence

The sequence of patterns to generate. Must be a list of (onset,generator) tuples. An empty list defaults to the single tuple: (0,self.input_generator), resulting in identical behavior to an ordinary GeneratorSheet.

Value:

param.List(default= [], doc= """The sequence of patterns to generate.  Must be a l

          single tuple: (0,self.input_generator), resulting in
