      extended by de.interactive_instruments.ShapeChange.Target.XmlSchema.SchematronConstraintNode.Unique
Enclosing class:
SchematronConstraintNode

public static class SchematronConstraintNode.Unique
extends SchematronConstraintNode

This class represents the isUnique iterator predicate. Being part of the Logic system Unique can be negated, which is realized by applying an additional not().

Constructor Detail

SchematronConstraintNode.Unique

public SchematronConstraintNode.Unique(SchematronSchema schemaObject,
                                       OclNode.Declaration vardecl,
                                       boolean neg)
Ctor

Parameters:
schemaObject - The schema object
vardecl - OclNode.Declaration object
neg - Negation flag
Method Detail

nodeVariableIsBoundTo

public SchematronConstraintNode nodeVariableIsBoundTo(OclNode.Declaration vardecl)
This method determines whether the Unique binds the given variable declaration and if it does, which is the expression the variable is bound to.

Overrides:
nodeVariableIsBoundTo in class SchematronConstraintNode
Parameters:
vardecl - The variable Declaration object
Returns:
Node the variable is bound to or null

translate

public SchematronConstraintNode.XpathFragment translate(SchematronConstraintNode.BindingContext ctx)

This compiles the node and its children to an Xpath expression fragment.

The object is translated in the given context. If negated an additional not() is applied.

Specified by:
translate in class SchematronConstraintNode
Parameters:
ctx - BindingContext this node shall be compiled in
Returns:
Object containing the fragment and its operator priority
