Method Detail

test

public abstract boolean test()

Deceides wheter this substitution is caried out or suppressed. Test is called for every occurence of the conditional tag, in list templates as often as the line is produced, if the tag is contained in a line. This is very useful for supressing different parts in different lines. Subclasses must implement this operation.
