public Screen(Metronome metronome)

Explicit Value Constructor.

Parameters:

metronome - The Metronome to use

Method Detail

addSuperimposition

public void addSuperimposition(Superimposition si)

Add a Superimposition.

Note: This method does not ensure that the order is correct.

Parameters:

si - The Superimposition to add

addTransition

public void addTransition(Transition t)

Add a Transition.

Note: This method does not ensure that the order is correct

Parameters:

t - The Transition to add

getFrameNumber

public int getFrameNumber()

Get the number of the current frame.

Returns:

The number of the current frame

getSuperimpositions

public java.util.Iterator<Superimposition> getSuperimpositions()

Get the current superimpositions (if any).

Returns:

The current superimpositions

getTransitions

public java.util.Iterator<Transition> getTransitions()

Get the current transitions (if any).

Returns:

The current transitions

getMetronome

public Metronome getMetronome()

Get the Metronome being used by this Screen.

Returns:

The Metronome

handleTick

public void handleTick(int time)

Handle tick events (required by MetronomeListener).

Specifically, make the current frame the "current" Content and call repaint() to start the rendering process.

Specified by:

handleTick in interface MetronomeListener

Parameters:

time - The current time (in millis)

iterator

public java.util.Iterator<SimpleContent> iterator()

Get an Iterator that contains the current SimpleContent object.

Overrides:

iterator in class Visualization

Returns:

The Iterator (containing 0 or 1 elements)

iterator

public java.util.Iterator<SimpleContent> iterator(boolean all)

Get an Iterator that contains either all of the SimpleContent objects or the current SimpleContent Object.

Parameters:

all - true to get all frames; false to get the current frame

Returns:

The SimpleContent objects

setRepeating

public void setRepeating(boolean repeating)

Set whether this presentation should repeat/loop.

Parameters:

repeating - true to repeat/loop; false otherwise

start

public void start()

Start the presentation.

stop

public void stop()

Stop the presentation.
