Class TimeBase

java.lang.Object
  com.kitfox.svg.animation.TimeBase

Direct Known Subclasses:

TimeCompound, TimeDiscrete, TimeIndefinite, TimeLookup, TimeSum

public abstract class TimeBase
extends Object

SVG has a complicated way of specifying time. Potentially, a time could be represened as a summation of discrete times and times of other animation events. This provides a root for the many elements we will need to define time.

parseTimeComponent

protected static TimeBase parseTimeComponent(String text)

evalTime

Calculates the (greater than or equal to 0) time in seconds this time represents. If the time cannot be determined, returns Double.NaN. If this represents an infinte amount of time, returns Double.POSITIVE_INFINITY.
