Class SvgSource.ParamTranslate

java.lang.Object

eu.bandm.tscore.base.Util.Pairwise<Event>

eu.bandm.music.top.SvgSource.ParamTranslate

Enclosing class:

SvgSource

protected class SvgSource.ParamTranslate
extends Util.Pairwise<Event>

Visits all events of a given iterator pairwise and writes out the Svg/Smil commands.

In the code generation scheme, the target value of an interpolation process is already encoded with the command starting the interpoloation. In non-interpolation, a "set value" command is generated at the time of the event. Symbolically:

                     #0      #1       #2      #3 
  first(): prepare registers

  pairwise():        \-------/
      ipol==true     v0=====>v1... 
      ipol==false    v0!...
  pairwise():                 \--------/
      ipol==true              v1=======>v2... 
      left value == reachedValue --> NOP (No need for a command iff value simply STAYS!)
      ipol==false             v1!...
  pairwise():                           \--------/ 
                                        etc.
  last() AND ipol=false:                        v3!...

  

ATTENTION:
"animateColor()" seems not necessary (even in examples in the w3c SVG docu!-)
"set()" does NOT affect settings of "@transform".

Method Detail

time

protected double time(Event e)

first

public void first(Event e)

Can be overridden by the user to visit the very first element before the first pair is visited by Util.Pairwise.pairwise(Object,Object). Here: Prepare the registers for the first call to pairwise(Event,Event).

Overrides:

first in class Util.Pairwise<Event>

writeSet

protected void writeSet()

Generate the source text which sets the parameter value only of the earlier event.

ATTENTION, HACK: "set" does not work with "@transform", so we use a VERY FAST animation.

pairwise

public void pairwise(Event predec,
                     Event current)

Must be overridden by the user to visit the define what to do with each pair of adjacent elements. These are visited in the sequential order of the underlying Iterator. On Execution, that has berformed a Iterator.next(), so that it "points" (e.g. with its Iterator.hasNext() to the successor of the later of both visited elements. Here: Generate either the source text which describes the interpolation between both events, or one which sets the parameter value only of the earlier event. Before processing, predecTime and predecValue correspond to the earlier event. After processing, predecTime and predecValue correspond to the later event = are prepared for the next cyclic call of this method.

Specified by:

pairwise in class Util.Pairwise<Event>

last

public void last(Event e)

Can be overridden by the user to visit the very last element after the last pair is visited by Util.Pairwise.pairwise(Object,Object).. Here: If the very last event's parameter is not reached by the last interpolation, then generate a "setValue" smil event.

Overrides:

last in class Util.Pairwise<Event>
