Class GeneratorSheet

source code

Sheet for generating a series of 2D patterns.

Typically generates the patterns by choosing parameters from a random distribution, but can use any mechanism.

__init__(self, **params)
x.__init__(...) initializes x; see x.__class__.__doc__ for signature

source code

generate(self)
Generate the output and send it out the Activity port.

source code

input_event(self, conn, data)
Called by the simulation when an EPConnectionEvent is delivered; the EventProcessor should process the data somehow.

source code

pop_input_generator(self)
Discard the current input_generator, and retrieve the previous one from the stack.

source code

push_input_generator(self)
Push the current input_generator onto a stack for future retrieval.

source code

set_input_generator(self, new_ig, push_existing=False)
Set the input_generator, overwriting the existing one by default.

source code

start(self)
Called by the simulation when the EventProcessor is added to the simulation.

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)

input_event(self, conn, data)

source code

Called by the simulation when an EPConnectionEvent is delivered; the EventProcessor should process the data somehow.

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

pop_input_generator(self)

source code

Discard the current input_generator, and retrieve the previous one from the stack.

Warns if no input_generator is available on the stack.

set_input_generator(self, new_ig, push_existing=False)

source code

Set the input_generator, overwriting the existing one by default.

If push_existing is false, the existing input_generator is discarded permanently. Otherwise, the existing one is put onto a stack, and can later be restored by calling pop_input_generator.

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

[hide private]

input_generator

Specifies a particular PatternGenerator type to use when creating patterns.

Value:

param.ClassSelector(PatternGenerator, default= Constant(), doc= """Specifies a par
ticular PatternGenerator type to use when creating patterns.""")

period

Delay (in Simulation time) between generating new input patterns.

Value:

param.Number(default= 1, bounds= (0, None), doc= "Delay (in Simulation time) betwe
en generating new input patterns.")

phase

Delay after the start of the Simulation (at time zero) before generating an input pattern. For a clocked, feedforward simulation, one would typically want to use a small nonzero phase and use delays less than the user-visible step size (typically 1.0), so that inputs are generated and processed before this step is complete.

Value:

param.Number(default= 0.05, doc= """
        Delay after the start of the Simulation (at time zero) before
