UniqueSolutions

object UniqueSolutions : NotableFlag

An implementation-specific flag controlling whether a solver's output solution sequence may contain multiple yes solutions carrying the same solved-query term (e.g. member(X, [1, 1, 1]) yielding three identical yes solutions with X = 1). Defaults to OFF (unaffected, standard behaviour); set to ON to keep only the first yes solution for each distinct solved-query term encountered, dropping any later duplicate.

Properties

admissibleValues

open override val admissibleValues: FlagDomain.Enumerated

Every legal value this flag may take.

open override val defaultValue: Term

The value this flag takes unless explicitly set otherwise.

open override val help: String

Markdown documentation exposed through help(flag(Name), Help).

open val isEditable: Boolean

Whether this flag's value can be changed at all (false for e.g. MaxArity).

open override val name: String

This flag's name, as it appears as the key in a FlagStore (e.g. "unknown", "double_quotes").

Every yes solution is emitted, even if its solved-query term repeats an earlier one.

val ON: Atom

Duplicate yes solutions (by solved-query term) are dropped.

Functions

isAdmissibleValue

open fun isAdmissibleValue(value: Term): Boolean

Whether value is one of admissibleValues.

open infix fun to(value: Term): Pair<String, Term>

This flag's name paired with value, ready to be inserted into a FlagStore.

open fun toPair(): Pair<String, Term>

This flag's name paired with its defaultValue, ready to be inserted into a FlagStore.
