Method Detail

pt

public IParticleI pt(int i)

getting end point. i==0 or i==1. if i is other value, returns first point.

particle

public IParticleI particle(int i)

alias of pt1()

pos

public IVec pos(int i)

position of particle(i)

pt1

public IParticleI pt1()

getting end point1.

particle1

public IParticleI particle1()

alias of pt1()

pos1

public IVec pos1()

position of particle1()

pt2

public IParticleI pt2()

getting end point2.

particle2

public IParticleI particle2()

alias of pt2()

pos2

public IVec pos2()

position of particle2()

parent

public IStick parent(IObject par)

Description copied from interface: ISubobject

setting parent object

Specified by:

parent in interface ISubobject

Overrides:

parent in class IDynamicsBase

target

public IStick target(IObject targetObj)

Description copied from class: IDynamicsBase

add terget object to be updated by this dynamic object.

Specified by:

target in interface IDynamics

Overrides:

target in class IDynamicsBase

removeTarget

public IStick removeTarget(int i)

Description copied from class: IDynamicsBase

remove target object.

Specified by:

removeTarget in interface IDynamics

Overrides:

removeTarget in class IDynamicsBase

removeTarget

public IStick removeTarget(IObject obj)

Description copied from class: IDynamicsBase

remove target object.

Specified by:

removeTarget in interface IDynamics

Overrides:

removeTarget in class IDynamicsBase

preupdate

public void preupdate()

after each particle receive all forces

Specified by:

preupdate in interface IDynamics

Overrides:

preupdate in class IDynamicsBase

postinteract

public void postinteract(java.util.ArrayList<IDynamics> agents)

Description copied from interface: IDynamics

executed after interact(ArrayList). behavior can be changed by IConfig.enablePostinteract and IConfig.loopPostinteract. If IConfig.loopPostinteract is false, preupdate is executed before post interact (updated 2012/08/26).

Specified by:

postinteract in interface IDynamics

Overrides:

postupdate

public void postupdate()

Description copied from interface: IDynamics

executed after update(). behavior can be changed by IConfig.enablePostupdate and IConfig.loopPostupdate.

Specified by:

postupdate in interface IDynamics

Overrides:

postupdate in class IDynamicsBase
