AxiomParentNodeWrapper

protected AxiomParentNodeWrapper(org.apache.axiom.om.OMContainer node)

Method Detail

getUnderlyingNode

public org.apache.axiom.om.OMContainer getUnderlyingNode()

Get the underlying Axiom node, to implement the VirtualNode interface

Specified by:

getUnderlyingNode in interface VirtualNode

Returns:

The underlying node.

atomize

public AtomicSequence atomize()

Get the typed value.

Specified by:

atomize in interface Item

Specified by:

atomize in interface NodeInfo

Overrides:

atomize in class AbstractNodeWrapper

Returns:

the typed value. If requireSingleton is set to true, the result will always be an AtomicValue. In other cases it may be a Value representing a sequence whose items are atomic values.

getStringValueCS

public java.lang.CharSequence getStringValueCS()

Get the value of the item as a CharSequence. This is in some cases more efficient than the version of the method that returns a String.

Specified by:

getStringValueCS in interface GroundedValue

Specified by:

getStringValueCS in interface Item

Returns:

the string value of the item

See Also:

Item.getStringValue()

hasChildNodes

public boolean hasChildNodes()

Determine whether the node has any children.

Note: the result is equivalent to getEnumeration(Axis.CHILD, AnyNodeTest.getInstance()).hasNext()

Specified by:

hasChildNodes in interface NodeInfo

Overrides:

hasChildNodes in class AbstractNodeWrapper

Returns:

True if the node has one or more children

generateId

public void generateId(FastStringBuffer buffer)

Get a character string that uniquely identifies this node. Note: a.isSameNode(b) if and only if generateId(a)==generateId(b)

Specified by:

generateId in interface NodeInfo

Parameters:

buffer - a buffer to contain a string that uniquely identifies this node, across all documents

iterateChildren

protected final AxisIterator iterateChildren(java.util.function.Predicate<? super NodeInfo> nodeTest)

Description copied from class: AbstractNodeWrapper

Return an iterator over the children of this node. This method is only called after checking that the node is an element or document.

Specified by:

iterateChildren in class AbstractNodeWrapper

Parameters:

nodeTest - a test that the returned attributes must satisfy

Returns:

an iterator over the child nodes, in document order.

iterateDescendants

protected AxisIterator iterateDescendants(java.util.function.Predicate<? super NodeInfo> nodeTest,
                                          boolean includeSelf)

Description copied from class: AbstractNodeWrapper

Return an iterator over the descendants of this node. This method is only called after checking that the node is an element or document node.

Overrides:

iterateDescendants in class AbstractNodeWrapper

Parameters:

nodeTest - a test that the returned descendants must satisfy

includeSelf - true if this node is to be included in the result

Returns:

an iterator over the sibling nodes, in axis order.
