Class quicktime.app.spaces.Sequencer 

java.lang.Object
   |
   +----quicktime.app.spaces.Sequencer
public abstract class Sequencer
extends Object
This interface defines operations that can control the positioning of a cursor through a sequence of data. Generally a sequencer will define a get method to retrieve the data at the current frame. The type of object returned in a get method is specific to the type of sequencer.

Variable Index

o kFirstFrame
o kLastFrame
o kLoopForwards
o kLoopPalindrome
o kNoLooping

Constructor Index

o Sequencer()

Method Index

o getCurrentFrame()
Returns the current frame number
o getLooping()
Returns the type of looping behaviour of the Sequencer.
o setCurrentFrame(int)
Sets the current frame number.
o setFrameNext()
Sets the current frame number to the next frame.
o setFramePrevious()
Sets the current frame number to the previous frame.
o setLooping(int)
Sets the type of looping behaviour of the Sequencer.
o size()
Returns the number of frames of the data which the sequencer is sequencing.
o toString()
Returns a string representation of this class.

Variables

o kNoLooping 
 public static final int kNoLooping
o kLoopForwards 
 public static final int kLoopForwards
o kLoopPalindrome 
 public static final int kLoopPalindrome
o kLastFrame 
 public static final int kLastFrame
o kFirstFrame 
 public static final int kFirstFrame

Constructors

o Sequencer 
 public Sequencer()

Methods

o setLooping 
 public void setLooping(int flag)
Sets the type of looping behaviour of the Sequencer.

Parameters:
flag - the looping flag
See Also:
kNoLooping, kLoopForwards, kLoopPalindrome
o getLooping 
 public int getLooping()
Returns the type of looping behaviour of the Sequencer.

Returns:
the looping behaviour flag
o size 
 public abstract int size()
Returns the number of frames of the data which the sequencer is sequencing.

Returns:
the current number of frames of the sequencers data sequence
o getCurrentFrame 
 public int getCurrentFrame()
Returns the current frame number

o setCurrentFrame 
 public void setCurrentFrame(int frameNumber)
Sets the current frame number. This will observe correct behaviour given the current state of the image object it refers to - it will loop, etc.

Parameters:
frameNumber - the new current frame number to set to.
o setFrameNext 
 public void setFrameNext()
Sets the current frame number to the next frame.

o setFramePrevious 
 public void setFramePrevious()
Sets the current frame number to the previous frame. Calling previousFrame where the index of the frame is currently the first index and looping is set to normal has no effect.

o toString 
 public String toString()
Returns a string representation of this class.

Overrides:
toString in class Object
