Class MixedAlternativesCollector

java.lang.Object

eu.bandm.tscore.base.ParameterCollector

eu.bandm.tscore.base.MixedAlternativesCollector

public class MixedAlternativesCollector
extends ParameterCollector

Compound collector to collect parameter tracks of arbitrarily mixed parameter values.
All alternatives may match arbitrarily often. (If that is not what you want, a second match has to be blocked one level below!)
The only restriction is, that the lexical representations of all combined ParameterCollectors are "LL(1)" distinguishable.
All alteratives (plus the text separation string as used when concatenating the parameter input strings, as defined in ParameterCollector.text_separator) are tested in a loop. The break condition of the loop is whenever the text pointer in the ULex.State object has not advanced, i.e. none of the alternatives has matched. Iff then there is still text left to parse, then an error message is generated.
finalizeEvent(Event) and finalizeTrack() are simply distributed over all alternatives.
