Constructor Detail

XmlUnmarshallingContext

public XmlUnmarshallingContext(int groupDepth)

Constructs a new XmlUnmarshallingContext

Parameters:

groupDepth - the maximum depth of an element mapped to a Group in the DOM

Method Detail

setRecordValue

public void setRecordValue(Object value)

Description copied from class: UnmarshallingContext

Sets the value of the record returned from the RecordReader

Specified by:

setRecordValue in class UnmarshallingContext

Parameters:

value - the record value read by a record reader

See Also:

RecordReader

pushIteration

public void pushIteration(Iteration b)

Description copied from class: ParsingContext

Pushes an Iteration onto a stack for adjusting field positions and indices.

Overrides:

pushIteration in class ParsingContext

Parameters:

b - the Iteration to push

See Also:

ParsingContext.popIteration()

popIteration

public Iteration popIteration()

Description copied from class: ParsingContext

Pops the last Iteration pushed onto the stack.

Overrides:

popIteration in class ParsingContext

See Also:

ParsingContext.pushIteration(Iteration)

getPreviousElement

public Element getPreviousElement()

Returns the last parsed DOM element for a field or bean collection.

Returns:

the last parsed element

setPreviousElement

public void setPreviousElement(Element e)

Sets the last parsed DOM element for a field or bean collection.

Parameters:

e - the last parsed element

getDocument

public Document getDocument()

Returns the XML document object model (DOM) for the current record.

Returns:

the XML document object model

getPosition

public Element getPosition()

Returns the current unmarshalled position in the DOM tree, or null if a node has not been matched yet.

Returns:

the current parent DOM node

See Also:

pushPosition(XmlNode, int, boolean), pushPosition(XmlNode)

pushPosition

public Element pushPosition(XmlNode node,
                            int depth,
                            boolean isGroup)

Updates position by finding a child of the current position that matches a given node. If isGroup is true, the node is indexed by its depth so that calls to this method for subsequent records in the same group can update position according to the depth of the record.

Parameters:

node - the XmlNode to match

depth - the depth of the node in the DOM tree

isGroup - whether the node is mapped to a Group

Returns:

the matched node or null if not matched

pushPosition

public Element pushPosition(XmlNode node)

Updates position by finding a child of the current position that matches a given node.

Parameters:

node - the XmlNode to match

Returns:

the matching element, or null if not found

See Also:

getPosition()

popPosition

public void popPosition()

Updates position to its parent (element), or null if the parent element is the document itself.

See Also:

getPosition()

findElement

public Element findElement(XmlNode node)

Finds a child element of the current position.

Parameters:

node - the XmlNodeUtil

Returns:

the matched element or null if not found

toRecordValue

public Object toRecordValue(Node node)

Description copied from class: UnmarshallingContext

Converts a Node to a record value.

Overrides:

toRecordValue in class UnmarshallingContext

Parameters:

node - the Node to convert

Returns:

the record value, or null if not supported
