static PJConverter |
allocate(Configuration config,
ItemType itemType,
int cardinality,
Class targetClass)
Factory method to instantiate a converter from a given XPath type to a given Java class |
static PJConverter |
allocateNodeListCreator(Configuration config,
Object node)
Static method to get a converter from an XPath sequence of nodes to the representation of a NodeList in an external object model (this is really a special for DOM, which uses NodeList rather than general purpose Java collection classes) |
abstract Object |
convert(ValueRepresentation<? extends Item> value,
Class targetClass,
XPathContext context)
Convert an XPath value to a Java value of a specified class |
static SequenceType |
getEquivalentItemType(Class javaClass)
