Class DiagnosisMarkUp

java.lang.Object

eu.bandm.tools.d2d2.infra.DiagnosisMarkUp

Direct Known Subclasses:

DiagnosisMarkUp.NoMarkup, DiagnosisMarkUp.VT100

public abstract class DiagnosisMarkUp
extends Object

Defines the string constants for presenting the parser situation to the user on a given type of terminal.

The string contants printed are needed to visually mark-up (for each stack frame printed) (a) the tag currently selected and (b) the set of all possible follower tags. (a) and (b) may apply to the same tag. The strings define the switching on and switching off of the three possible combinations.

The two non-abstract methods are fall-back implementations and simply concatenate the two dedicated strings.
