Class AWBinding

java.lang.Object
  ariba.ui.aribaweb.util.AWBaseObject
      ariba.ui.aribaweb.core.AWBinding

All Implemented Interfaces:

AWObject, java.lang.Cloneable

public abstract class AWBinding
extends AWBaseObject
implements java.lang.Cloneable

Represents a binding between a named property and a constant or dynamic expression in the context of the parent component.

Many binding subtypes are supported, including:

1. AWConstantBinding: e.g.: "10" or "A long string"
2. AWKeyPathBinding: e.g.: "$userName" or "$project.costCenter.budget" or "$delete"
3. AWExpressionBinding: e.g. '${firstName + " " + lastName}' or '${pageWithName("Page2")}'
4. AWLocalizedBinding: e.g. "$[a002]Delete Items"
