All Implemented Interfaces:

MergeHandler

public class MergeHandlerAdapter

public MergeHandler[] getChildren()

Description copied from interface: MergeHandler

Retrieve any child merge handlers associated with this handler. Child merge handlers may be added alter merge behavior for a subsection of the merge area defined by this merge handler.

Specified by:

getChildren in interface MergeHandler

Returns:

child merge handlers

getName

public String getName()

Description copied from interface: MergeHandler

Retrieve the name associated with this merge handlers. Merge handler names are period-delimited numeric strings that define the hierarchical relationship of mergehandlers and their children. For example, "2" could be used to define the second handler in the configuration list and "2.1" would be the name describing the first child handler of "2".

Specified by:

getName in interface MergeHandler

Returns:

the period-delimited numeric string that names this handler

getPriority

public int getPriority()

Description copied from interface: MergeHandler

Retrieve the priority for the handler. Priorities are used by the MergeManager to establish the order of operations for performing merges.

Specified by:

getPriority in interface MergeHandler

Returns:

the priority value

getXPath

public String getXPath()

Description copied from interface: MergeHandler

Retrieve the XPath query associated with this handler. XPath is used by the handler to define to section of the source and patch documents that will be merged.

Specified by:

getXPath in interface MergeHandler

Returns:

the xpath query

merge

public Node[] merge(NodeList nodeList1,
                    NodeList nodeList2,
                    List<Node> exhaustedNodes)

Description copied from interface: MergeHandler

Perform the merge using the supplied list of nodes from the source and patch documents, respectively. Also, a list of nodes that have already been merged is provided and may be used by the implementation when necessary.

Specified by:

merge in interface MergeHandler

Parameters:

nodeList1 - list of nodes to be merged from the source document

nodeList2 - list of nodes to be merged form the patch document

exhaustedNodes - already merged nodes

Returns:

list of merged nodes

setChildren

public void setChildren(MergeHandler[] children)

Description copied from interface: MergeHandler

Set the child merge handlers

Specified by:

setChildren in interface MergeHandler

setName

public void setName(String name)

Description copied from interface: MergeHandler

Set the period-delimited numeric string that names this handler

Specified by:

setName in interface MergeHandler

setPriority

public void setPriority(int priority)

Description copied from interface: MergeHandler

Set the priority for this handler

Specified by:

setPriority in interface MergeHandler

setXPath

public void setXPath(String xpath)

Description copied from interface: MergeHandler

Set the xpath query

Specified by:

setXPath in interface MergeHandler
