RandomMove

The class RandomMove is derived from Action lets agents move in random directions. This class can be used for simulationg diffusion.

Code:
RandomMove.h
RandomMove.cpp

Attributes:

ATTR_RANDOMMOVE_NAME

“RandomMove”

action name

ATTR_RANDOMMOVE_PROB_NAME

“RandomMove_prob”

move probability

Public Methods

constructors

RandomMove(SPopulation<T> *pPop, SCellGrid *pCG, const std::string sActionName, const std::string sID);
RandomMove();

Calls the base class’s constructor and saves the action name.

pPop

A pointer to the SPopulation object performing this action.

pCG

A pointer to the SCellGrid object on which the simulation runs.

sActionName

Name of this action.

sID

An ID for this action.

destructor

virtual ~RandomMove();

The destructor.

execute

virtual int execute(int iAgentIndex, float fT);
iAgentIndex

Current agent’s index.

fT

Simulation time.

This method is called for all agents (in parallel).
Each agent is moved with a move probability, and if it moves, the direction is choesen randomly.

extractAttributes

virtual int extractAttributesQDF(hid_t hSpeciesGroup);
hSpeciesGroup

HDF handle for the species group to read from.

This method reads the move probability from a QDF file.

writeAttributes

virtual int writeAttributesQDF(hid_t hSpeciesGroup);
hSpeciesGroup

HDF handle for the species group to write to.

This method writes the move probability to the specified group in a QDF file.

tryGetAttributes

virtual int tryGetAttributes(const ModuleComplex *pMC);
pMC

A ModuleComplex object.

Extracts the move probability from the ModuleComplex object.

modifyAttributes

virtual int modifyAttributes(const std::string sAttrName, double dValue);
sAttrName

Name of attribute to change.

dValue

Value to set the attribute to.

The only attribute that can be changed is obviously "RandomMove_prob".

isEqual

virtual bool isEqual(Action<T> *pAction, bool bStrict);
pAction

Pointer to an action object to compare with this.

bStrict

Strictness of comparisons (ignored here).

pAction is equal to this, if it is a RandomMove object whose mpve probability is the same as the one of this.
