Constructor & Destructor Documentation

UwGMPosition()

UwGMPosition::UwGMPosition

(

)

Constructor of UwGMPosition class.

Member Function Documentation

command()

int UwGMPosition::command ( int  argc, const char *const *  argv  )

virtual

TCL command interpreter.

It implements the following OTcl methods:

Parameters

argc	Number of arguments in argv.
argv	Array of strings which are the command parameters (Note that argv[0] is the name of the object).

Returns

TCL_OK or TCL_ERROR whether the command has been dispatched successfully or not.

Definition at line 103 of file uwgmposition.cpp.

Gaussian()

double UwGMPosition::Gaussian ( )

private

Method that returns a value from a normal random Gaussian variable (zero mean, unitary viariance)

Definition at line 140 of file uwgmposition.cpp.

getX()

double UwGMPosition::getX ( )

protectedvirtual

Returns the current projection of the node on the x-axis.

If it's necessary (updating time ia expired), update the position values before returns it.

Returns

The new x-axis position value of the node.

Definition at line 297 of file uwgmposition.cpp.

getY()

double UwGMPosition::getY ( )

protectedvirtual

Returns the current projection of the node on the y-axis.

If it's necessary (updating time ia expired), update the position values before returns it.

Returns

The new y-axis position value of the node.

Definition at line 306 of file uwgmposition.cpp.

getZ()

double UwGMPosition::getZ ( )

protectedvirtual

Returns the current projection of the node on the z-axis.

If it's necessary (updating time ia expired), update the position values before returns it.

Returns

The new z-axis position value of the node.

Definition at line 315 of file uwgmposition.cpp.

update()

void UwGMPosition::update ( double  now )

privatevirtual

Method that updates both the position coordinates as function of the number of states to be evaluated.

Definition at line 147 of file uwgmposition.cpp.

Definition at line 123 of file uwgmposition.h.

updateTime_

double UwGMPosition::updateTime_

protected

Defines the behaviour of the node when it reaches the edge: SPHERIC: return in the simulation field on the opposite side THOROIDAL: return in the centre of simulation field HARDWALL: the movement is stopped in the edge REBOUNCE: the node rebounce (i.e., the movement that should be outside the simulation field is mirrored inside)

Time between two update computation.
