Module type Fix.SEMI_LATTICE

The signature SEMI_LATTICE offers separate leq and join functions. The functor Glue.MinimalSemiLattice can be used, if necessary, to convert this signature to MINIMAL_SEMI_LATTICE.

type property

The type property must form a partial order, which must satisfy the ascending chain condition: every monotone sequence must eventually stabilize.

val leq : property -> property -> bool

leq p q determines whether p <= q holds.

val join : property -> property -> property

join p q is the least upper bound of the properties p and q.
