| AbstractFactory | | abstract public class AbstractFactory (Code) | | The
JXPathContext.createPath JXPathContext.createPath() method of
JXPathContext can create missing objects as it traverses an XPath; it
utilizes an AbstractFactory for that purpose. Install a factory on
JXPathContext by calling
JXPathContext.setFactory JXPathContext.setFactory() .
All methods of this class return false. Override any of them to return true
to indicate that the factory has successfully created the described object.

| createObject | | public boolean createObject(JXPathContext context, Pointer pointer, Object parent, String name, int index)(Code) | | The parameters may describe a collection element or an individual
object. It is up to the factory to infer which one it is. If it is a
collection, the factory should check if the collection exists. If not,
it should create the collection. Then it should create the index'th
element of the collection and return true.
Parameters:
context - can be used to evaluate other XPaths, get to variablesetc.
Parameters:
pointer - describes the location of the node to be created
Parameters:
parent - is the object that will server as a parent of the newobject
Parameters:
name - is the name of the child of the parent that needs to becreated. In the case of DOM may be qualified.
Parameters:
index - is used if the pointer represents a collection element. Youmay need to expand or even create the collection to accomodate the newelement. true if the object was successfully created |
| declareVariable | | public boolean declareVariable(JXPathContext context, String name)(Code) | | Declare the specified variable
Parameters:
context - hosts variable pools. See JXPathContext.getVariables JXPathContext.getVariables()
Parameters:
name - is the name of the variable without the "$" sign true if the variable was successfully defined |
