Class XmlSchemaPathNode<U,V>

java.lang.Object

org.apache.ws.commons.schema.docpath.XmlSchemaPathNode<U,V>

public final class XmlSchemaPathNode<U,V>
extends java.lang.Object

This represents a node in the path when walking an XML or Avro document. As XmlSchemaPathFinder walks through an XML document, it builds XmlSchemaPathNodes representing the path walked, and XmlSchemaDocumentNodes representing where the XML document's elements fall in the XML Schema's sequences, choices, and all groups.

Constructor Detail

XmlSchemaPathNode

XmlSchemaPathNode(XmlSchemaPathNode.Direction dir,
                  XmlSchemaPathNode<U,V> previous,
                  XmlSchemaDocumentNode<U> node)

XmlSchemaPathNode

XmlSchemaPathNode(XmlSchemaPathNode.Direction dir,
                  XmlSchemaPathNode<U,V> previous,
                  XmlSchemaStateMachineNode stateMachine)

Method Detail

getDocumentNode

public XmlSchemaDocumentNode<U> getDocumentNode()

Retrieves the XmlSchemaDocumentNode this XmlSchemaPathNode is visiting.

getStateMachineNode

public XmlSchemaStateMachineNode getStateMachineNode()

Retrieves the XmlSchemaStateMachineNode representing the XML Schema that this XmlSchemaPathNode is visiting. This is equivalent to calling getDocumentNode().getStateMachineNode().

getDirection

public XmlSchemaPathNode.Direction getDirection()

The direction this path travels.

getIteration

public int getIteration()

The iteration through the underlying XmlSchemaDocumentNode. If the path traverses the same XmlSchemaDocumentNode twice, XmlSchemaDocumentNode.getIteration() will return two, and one getIteration() will return one, while the other will return two.

getMinOccurs

public long getMinOccurs()

Shortcut for calling getStateMachineNode().getMinOccurs().

See Also:

XmlSchemaStateMachineNode.getMinOccurs()

getMaxOccurs

public long getMaxOccurs()

Shortcut for calling getStateMachineNode().getMaxOccurs().

See Also:

XmlSchemaStateMachineNode.getMaxOccurs()

getDocIteration

public int getDocIteration()

Shortcut for calling getDocumentNode().getIteration().

See Also:

XmlSchemaDocumentNode.getIteration()

getPrevious

public XmlSchemaPathNode<U,V> getPrevious()

The previous node in the path, or null if at the beginning of the path.

getNext

public XmlSchemaPathNode<U,V> getNext()

The next node in the path, or null if at the end of the path.

getIndexOfNextNodeState

int getIndexOfNextNodeState()

getDocSequencePosition

int getDocSequencePosition()

setIteration

void setIteration(int newIteration)

setDocumentNode

void setDocumentNode(XmlSchemaDocumentNode<U> docNode)

setNextNode

void setNextNode(int nextNodeIndex,
                 XmlSchemaPathNode<U,V> newNext)

setPreviousNode

XmlSchemaPathNode<U,V> setPreviousNode(XmlSchemaPathNode<U,V> newPrevious)

Changes the previous node this one was pointing to. This is useful when cloning prior nodes in the chain.

Parameters:

newPrevious - The new previous node.

Returns:

The old previous node.

update

void update(XmlSchemaPathNode.Direction newDirection,
            XmlSchemaPathNode<U,V> newPrevious,
            XmlSchemaDocumentNode<U> newNode)

Use this method when changing the the XmlSchemaStateMachineNode this DocumentPathNode refers to. The next node in the path is returned, as it will be discarded internally.

Parameters:

newPrevious - The new previous DocumentPathNode this node is traversed from.

newNode - The new XmlSchemaStateMachineNode this node refers to.

update

void update(XmlSchemaPathNode.Direction newDirection,
            XmlSchemaPathNode<U,V> newPrevious,
            XmlSchemaStateMachineNode newStateMachineNode)

getUserDefinedContent

public V getUserDefinedContent()

Retrieves any user-defined content attached to this XmlSchemaPathNode, or null if none.

setUserDefinedContent

public void setUserDefinedContent(V content)

Attaches user-defined content to this XmlSchemaPathNode.
