Method Detail

stop

void stop()

stop activity in this AnimationControl

run

void run()

a single invocation implements anmation behavior until stop() is called

setCurrent

void setCurrent(int c)
         throws VisADException,
                RemoteException

set the current ordinal step number

Parameters:

c - - value for current ordinal step number

Throws:

VisADException - - a VisAD error occurred

RemoteException - - an RMI error occurred

setCurrent

void setCurrent(double value)
         throws VisADException,
                RemoteException

set the current step by the value of the RealType mapped to Display.Animation

Parameters:

value - - RealType value that is converted to an ordinal step number

Throws:

VisADException - - a VisAD error occurred

RemoteException - - an RMI error occurred

getCurrent

int getCurrent()

Returns:

the current ordinal step number

setDirection

void setDirection(boolean dir)
           throws VisADException,
                  RemoteException

Set the animation direction.

Parameters:

dir - true for forward, false for backward

Throws:

VisADException - Couldn't create necessary VisAD object. The direction remains unchanged.

RemoteException - Java RMI exception

getDirection

boolean getDirection()

Get the animation direction.

Returns:

true for forward, false for backward

getStep

long getStep()

Returns:

the dwell time for the current step (in ms)

getSteps

long[] getSteps()

Returns:

an array of the dwell times for all the steps (in ms)

setStep

void setStep(int st)
      throws VisADException,
             RemoteException

Set the dwell rate between animation steps to a constant value

Parameters:

st - dwell time in milliseconds

Throws:

VisADException - Couldn't create necessary VisAD object. The dwell time remains unchanged.

RemoteException - Java RMI exception

setSteps

void setSteps(int[] steps)
       throws VisADException,
              RemoteException

set the dwell time for individual steps.

Parameters:

steps - an array of dwell times in milliseconds for each step in the animation. If the length of the array is less than the number of frames in the animation, the subsequent step values will be set to the value of the last step.

Throws:

VisADException - Couldn't create necessary VisAD object. The dwell times remain unchanged.

RemoteException - Java RMI exception

takeStep

void takeStep()
       throws VisADException,
              RemoteException

advance one step (forward or backward)

Throws:

VisADException - Couldn't create necessary VisAD object. No step is taken.

RemoteException - Java RMI exception

init

void init()
   throws VisADException

actually set Switches (Java3D) or VisADSwitches (Java2D) to child nodes corresponding to current ordinal step number

Throws:

VisADException - - a VisAD error occurred.

getSet

Set getSet()

Returns:

Set of RealType values for animation steps, in RealType mapped to Animation

setSet

void setSet(Set s)
     throws VisADException,
            RemoteException

Sets the set of times in this animation control, in RealType mapped to Animation. If the argument set is equal to the current set, then nothing is done.

Parameters:

s - The set of times.

Throws:

VisADException - if a VisAD failure occurs.
