      Description copied from class: PropertyOwnerPointer
      Get a PropertyPointer for this PropertyOwnerPointer.

    • getName

      public QName getName()
      Description copied from class: NodePointer
      Returns the name of this node. Can be null.

      Returns:
      QName
    • getBaseValue

      public Object getBaseValue()
      Description copied from class: NodePointer
      Returns the value represented by the pointer before indexing. So, if the node represents an element of a collection, this method returns the collection itself.
      Specified by:
      getBaseValue in class NodePointer
      Returns:
      Object value
    • isCollection

      public boolean isCollection()
      Returns true if the value of the pointer is an array or a Collection.
      Specified by:
      isCollection in class NodePointer
      Returns:
      false
    • getLength

      public int getLength()
      If the pointer represents a collection (or collection element), returns the length of the collection. Otherwise returns 1 (even if the value is null).
      Specified by:
      getLength in class NodePointer
      Returns:
      1
    • isLeaf

      public boolean isLeaf()
      Description copied from class: NodePointer
      If true, this node does not have children
      Specified by:
      isLeaf in class NodePointer
      Returns:
      boolean
    • hashCode

      public int hashCode()
      Overrides:
      hashCode in class Object
    • equals

      public boolean equals(Object object)
      Overrides:
      equals in class Object
    • asPath

      public String asPath()
      Returns an XPath that maps to this Pointer. If the pointer has a parent, then parent's path. If the bean is null, "null()". If the bean is a primitive value, the value itself. Otherwise - an empty string.
      Specified by:
      asPath in interface Pointer
      Overrides:
      asPath in class NodePointer
      Returns:
