org.apache.commons.jxpath.ri.model.beans.BeanPointer
- All Implemented Interfaces:
Serializable,Cloneable,Comparable,Pointer
A Pointer that points to a JavaBean or a collection. It is either the first element of a path or a pointer for a property value. Typically there is a
BeanPropertyPointer between two BeanPointers in the chain.- See Also:

Method Details
-
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:
asPathin interfacePointer- Overrides:
asPathin classNodePointer- Returns:
- String XPath expression
-
equals
-
getBaseValue
Description copied from class:NodePointerGets 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:
getBaseValuein classNodePointer- Returns:
- Object value
-
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:
getLengthin classNodePointer- Returns:
- 1
-
getName
Description copied from class:NodePointerGets the name of this node. Can be null.- Specified by:
getNamein classPropertyOwnerPointer- Returns:
- QName The name of this node. Can be null.
-
getPropertyPointer
Description copied from class:PropertyOwnerPointerGets a PropertyPointer for this PropertyOwnerPointer.- Specified by:
getPropertyPointerin classPropertyOwnerPointer- Returns:
- PropertyPointer
-
hashCode
-
isCollection
Returnstrueif the value of the pointer is an array or a Collection.- Specified by:
isCollectionin classNodePointer- Returns:
- false
-
isLeaf
Description copied from class:NodePointerIf true, this node does not have children- Specified by:
isLeafin classNodePointer- Returns:
- boolean
