Abstract methods
Further constrain a symbol already present in the constraint.
Further constrain a symbol already present in the constraint.
Attributes
Add symbols to constraint, correctly handling inter-dependencies.
Add symbols to constraint, correctly handling inter-dependencies.
Attributes
- See also:
Immediate bounds of sym. Does not contain lower/upper symbols (see fullBounds).
Is the symbol registered in the constraint?
Is the symbol registered in the constraint?
Attributes
- Note:
this is true even if the symbol is constrained to be equal to another type, unlike Constraint.contains.
Full bounds of sym, including TypeRefs to other lower/upper symbols.
Full bounds of sym, including TypeRefs to other lower/upper symbols.
Attributes
- Note:
this performs subtype checks between ordered symbols. Using this in isSubType can lead to infinite recursion. Consider
boundsinstead.
Is sym1 ordered to be less than sym2?
Is sym1 ordered to be less than sym2?
Attributes
GADT constraint narrows bounds of at least one variable
GADT constraint narrows bounds of at least one variable
Attributes
Restore the state from other GadtConstraint, probably copied using fresh
