long FiringRateSim::Neurons::PacemakerNeuron::CalculateSnapshotByteSize ( )

Calculates the snapshot byte size.

Sometimes the user may want to capture a snapshot of the simulation at a given point in time, and then be able to go back to that specific point. To do this we grab a snapshot of all the data in the system, including the neural variables. We essentially serialize the data into a binary format for later re-use. This method calculates the number of bytes that will be required to store the entire object.

Here is the call graph for this function:

float * FiringRateSim::Neurons::PacemakerNeuron::GetDataPointer ( const std::string & strDataType )

virtual

Returns a float pointer to a data item of interest in this object.

This is a generic method used to get a pointer to data variable of interest. It is used by a variety of systems in the simulation. The most prominent are the data charting and stimulus classes. Within this method we associate a variable with a string name. By passing in the name of the data type we are interested in we can recieve back a float pointer to that data type. We can use that to read or set the data item in other classes. For example, the data charting system gets the pointer and then each time it needs to log a data point it reads the value into an array.

Author: dcofer

Date: 2/22/2011

Parameters

strDataType name of the data item for which we are looking.

Returns: float pointer of the data item. If not found then it throws an exception.

Exceptions

If	DataType is not found.

Parameters

strDataType	string name of the data type to set.
strValue	The string value of the data. It is up to the developer to determine what this should be. For example, in most cases it is simply a float and you just have to convert it to a float and make the appropriate mutator method call. However, it can be any type of string, including an entire xml packet. It is the developers responsibility to know how to set and process the data as required.
bThrowError	true to throw error if there is a problem. If false then it will not return an error, just return false.

Returns: true if it succeeds, false if it fails.

Here is the call graph for this function:

void FiringRateSim::Neurons::PacemakerNeuron::StepSimulation ( )

virtual

Step the simulation for this object.

This is called on an object each time it is stepped in the simulation. this is where its simulation code is processed. However, StepSimulation is not necessarily called every single time that the simulation as a whole is stepped. A good example of this is that neural modules can have different integration time steps. So a firing rate module may have a DT of 0.5 ms, while an integrate and fire model may have one of 0.1 ms. So the firing rate module would only get its StepSimulation method called every 5th time that the other module was called. This is all handed in the StepSimulation method of the Simulator and NervousSystem.
