Class XpathConstraintNode.Unique
java.lang.Object
de.interactive_instruments.ShapeChange.TargetHelper.XpathConstraintNode
de.interactive_instruments.ShapeChange.TargetHelper.XpathConstraintNode.Unique
- Enclosing class:
- XpathConstraintNode
public static class XpathConstraintNode.Unique
- extends XpathConstraintNode
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().

XpathConstraintNode.Unique
public XpathConstraintNode.Unique(XpathHelper xpathHelper,
OclNode.Declaration vardecl,
boolean neg)
- Ctor
- Parameters:
xpathHelper
- The schema objectvardecl
- OclNode.Declaration objectneg
- Negation flag
bindsVariable
public boolean bindsVariable(OclNode.Declaration vardecl)
- This method determines whether the Unique binds the given variable
declaration.
- Overrides:
bindsVariable
in class XpathConstraintNode
- Parameters:
vardecl
- The variable Declaration object
- Returns:
- Flag indicating the requested property
translate
public XpathConstraintNode.XpathFragment translate(XpathConstraintNode.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 XpathConstraintNode
- Parameters:
ctx
- BindingContext this node shall be compiled in
- Returns:
- Object containing the fragment and its operator priority
