explanationTree.letStep8=bestimmen. Da der Let-Ausdruck und der innere Term vom gleichen Typ sind, muss außerdem die \
|
||||
Bedingung
|
||||
explanationTree.letStep9=der Constraintmenge hinzugefügt werden.
|
||||
|

expUnification.initial1=In den folgenden Schritten wird der Unifikationsalgorithmus auf der Constraintmenge ausgeführt, \

||||
um den Typen des eingegebenen Terms zu bestimmen.
|
||||
expLetUnification.initial1=In den folgenden Schritten wird der Unifikationsalgorithmus auf der Constraintmenge \
|
||||
ausgeführt, um den Typen der let-Variable zu finden und damit die neue Typumgebung zu bestimmen.
|
||||
expUnification.trivial1=In diesem Schritt wurde der Constraint
|
||||
expUnification.trivial2=entfernt. Da linke und rechte Seite identisch sind, ist der Constraint immer erfüllt und \
|
||||
wird somit nicht benötigt.
|
||||
expUnification.variable1=In diesem Schritt wurde der Constraint
|
||||
expUnification.variable2=ersetzt. Da t ein Variablentyp ist und nicht in
|
||||
expUnification.variable3=vorkommt, können alle Vorkommen von
|
||||
expUnification.variable4=durch
|
||||
expUnification.variable5=ersetzt werden. In der Folge wird die Substitution
|
||||
expUnification.variable6=erstellt und auf die übrige Constraintmenge angewandt. Die daraus resultierenden Veräderungen \
|
||||
sind blau markiert.
|
||||
expUnification.function1=In diesem Schritt wurde der Constraint
|
||||
expUnification.function2=ersetzt. Da sowohl
|
||||
expUnification.function3=als auch
|
||||
expUnification.function4=Funktionstypen sind, müssen die beiden Constraints
|
||||
expUnification.function5=und
|
||||
expUnification.function6=der Constraintmenge hinzugefügt werden. Der ursprüngliche Constraint
|
||||
expUnification.function7=wurde aus der Menge entfernt.
|
||||
expUnification.mgu1=In diesem Schritt wird der allgemeinste Unifikator
|
||||
expUnification.mgu2=der Constraintmenge
|
||||
expUnification.mgu3=berechnet. Dafür wird die gesamte Menge an Substitutionen auf jede einzelne der Substitutionen \
|
||||
aus der Menge angewandt.
|
||||
expUnification.finalType1=In diesem Schritt wird der zuvor berechnete allgemeinste Unifikator
|
||||
expUnification.finalType2=auf den Typen
|
||||
expUnification.finalType3=des eingegebenen Terms angewandt. Das Ergebnis
|
||||
expUnification.finalType4=ist der finale Type des eingegebenen Terms.
|
||||
expUnification.infiniteType=Eine Typvariable taucht auf beiden Seiten des hervorgehobenen Constraints auf. \
|
||||
Da sich hier ein unendlicher Typ ergeben würde, bricht die Unifikation ab.
|
||||
expUnification.diffrentTypes=Da die Typen auf den beiden Seiten des hervorgehobenen Constraints nicht übereinstimmen, \
|
||||
bricht die Unifikation hier ab.
|
||||
expLetUnification.finalType1=In diesem Schritt wird der zuvor berechnete allgemeinste Unifikator
|
||||
expLetUnification.finalType2=auf den Typen
|
||||
expLetUnification.finalType3=der Let-Definition angewandt. Das Ergebnis
|
||||
expLetUnification.finalType4=ist der finale Typ der Let-Definition.
|
||||
expLetUnification.typeAss1=In diesem Schritt werden die Typannahmen
|
||||
expLetUnification.typeAss2=für die weitere Durchführung des Algorithmus berechnet. Im ersten Schritt wird dafür der MGU
|
||||
expLetUnification.typeAss3=der Let-Teilinferenz auf die aktuelle Menge von Typannahmen angewandt. Die dadurch entstandenen \
|
||||
Typannahmen werden anschließend der Menge
|
||||
expLetUnification.typeAss4=hinzugefügt. Im zweiten Schritt wird der Typ der let-Variable
|
||||
expLetUnification.typeAss5=berechnet. Dafür wird Typabstraktion
|
||||
expLetUnification.typeAss6=zuerst instanziiert und dann gemeinsam mit der Variable
|
||||
expLetUnification.typeAss7=als Typannahme der Menge
|
||||
expLetUnification.typeAss8=hinzugefügt. Bei der Instanziierung werden alle Typvariablen, die frei in
|
||||
expLetUnification.typeAss9=aber nicht frei in
|
||||
expLetUnification.typeAss10=vorkommen allquantifiziert.
|
||||
expLetUnification.letStep1=Die Let-Teilinferenz ist jetzt abgeschlossen. Der Typinferenz-Algorithmus wird mit der um
|
||||
expLetUnification.letStep2=erweiterten Constraintmenge und den neu berechneten Typannahmen fortgeführt.
