Label |
label()
The nested label.
|
boolean |
leq_(Label L,
LabelEnv env,
LabelEnv.SearchState state)
Implementation of leq, should only be called by JifTypeSystem
|
Label |
subst(LabelSubstitution substitution) |

throwTypes(polyglot.types.TypeSystem ts)
If the label is runtime representable, when it is evaluated at runtime it
may throw exceptions.
|

toString(java.util.Set<Label> printedLabels)
return a string representation of the label.
|

Label
For example, an UnknownLabel is not comparable to others, neither is a VarLabel. Most other labels are.

public boolean isEnumerable()
Label
For example, Singletons are enumerable, JoinLabels are enumerable, RuntimeLabel (the label of all runtime representable components) is not enumerable. NOTE: The components of a label are not neccessarily stuck together with a join operation. For example, the MeetLabel uses the meet operation between its components.
