before_run
(run_namespace)Optional method to prepare the object before a run.
check_variable_write
(variable)Function that can be overwritten to raise an error if writing to a variable should not be allowed.

The
SpikeQueue
- before_run(run_namespace)[source]
Optional method to prepare the object before a run.
Called by
Network.after_run
before the main simulation loop starts.
- check_variable_write(variable)[source]
Function that can be overwritten to raise an error if writing to a variable should not be allowed. Note that this does not deal with incorrect writes that are general to all kind of variables (incorrect units, writing to a read-only variable, etc.). This function is only used for type-specific rules, e.g. for raising an error in
Synapses
when writing to a synaptic variable before anyconnect
call.By default this function does nothing.
- update_abstract_code(run_namespace=None, level=0)[source]
Update the abstract code for the code object. Will be called in
before_run
and should update theCodeRunner.abstract_code
attribute.Does nothing by default.
