LangAttributePointer
public LangAttributePointer(NodePointer parent)
Create a new LangAttributePointer.- Parameters:
parent
- parent pointer.
-
-
Method Detail
-
getName
public QName getName()
Description copied from class:NodePointer
Returns the name of this node. Can be null.- Specified by:
getName
in classNodePointer
- Returns:
- QName
-
getNamespaceURI
public java.lang.String getNamespaceURI()
Description copied from class:NodePointer
Returns the namespace URI associated with this Pointer.- Overrides:
getNamespaceURI
in classNodePointer
- Returns:
- String uri
-
isCollection
public boolean isCollection()
Description copied from class:NodePointer
Returnstrue
if the value of the pointer is an array or a Collection.- Specified by:
isCollection
in classNodePointer
- Returns:
- boolean
-
getLength
public int getLength()
Description copied from class:NodePointer
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 classNodePointer
- Returns:
- int
-
getBaseValue
public java.lang.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 classNodePointer
- Returns:
- Object value
-
getImmediateNode
public java.lang.Object getImmediateNode()
Description copied from class:NodePointer
Returns the object the pointer points to; does not convert it to a "canonical" type.- Specified by:
getImmediateNode
in classNodePointer
- Returns:
- Object node
-
isLeaf
public boolean isLeaf()
Description copied from class:NodePointer
If true, this node does not have children- Specified by:
isLeaf
in classNodePointer
- Returns:
- boolean
-
setValue
public void setValue(java.lang.Object value)
Converts the value to the required type and changes the corresponding object to that value. Throws UnsupportedOperationException.- Specified by:
setValue
in interfacePointer
- Specified by:
setValue
in classNodePointer
- Parameters:
value
- Object
-
asPath
public java.lang.String asPath()
Description copied from class:NodePointer
Returns an XPath that maps to this Pointer.- Specified by:
asPath
in interfacePointer
- Overrides:
asPath
in classNodePointer
- Returns:
- String xpath expression
-
hashCode
public int hashCode()
- Overrides:
hashCode

-
testNode
public boolean testNode(NodeTest test)
Description copied from class:NodePointer
Checks if this Pointer matches the supplied NodeTest.- Overrides:
testNode
in classNodePointer
- Parameters:
test
- the NodeTest to execute- Returns:
- true if a match
-
compareChildNodePointers
public int compareChildNodePointers(NodePointer pointer1, NodePointer pointer2)
Description copied from class:NodePointer
Compares two child NodePointers and returns a positive number, zero or a positive number according to the order of the pointers.- Specified by:
compareChildNodePointers
in classNodePointer
- Parameters:
pointer1
- first pointer to be comparedpointer2
- second pointer to be compared- Returns:
- int per Java comparison conventions
