java.lang.Object
de.interactive_instruments.ShapeChange.TargetHelper.XpathConstraintNode
de.interactive_instruments.ShapeChange.TargetHelper.XpathConstraintNode.Size
- Enclosing class:
- XpathConstraintNode
public static class XpathConstraintNode.Size
- extends XpathConstraintNode
This class represents an OCL invocation of the size operation. Size
can be applied to anything with a -> and returns the number of elements
of the object interpreted as a collection. If applied to a String it
determines its length.

XpathConstraintNode.Size
public XpathConstraintNode.Size(XpathHelper xpathHelper,
boolean set)
- Ctor
- Parameters:
xpathHelper
- The schema objectset
- Flag: This is a set operation
translate
public XpathConstraintNode.XpathFragment translate(XpathConstraintNode.BindingContext ctx)
Compile to an equivalent Xpath expression. The Set variant is
compiled to count() and the String variant goes to string-length().
- Specified by:
translate
in class XpathConstraintNode
- Parameters:
ctx
- BindingContext this node shall be compiled in
- Returns:
- Object containing the Xpath fragment
