static PJConverter |
allocate(Configuration config,
ItemType itemType,
int cardinality,
java.lang.Class targetClass)
Factory method to instantiate a converter from a given XPath type to a given Java class
|
static PJConverter |
allocateNodeListCreator(Configuration config,
java.lang.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)
|
java.lang.String |
compile(java.lang.String var,
java.lang.Class targetClass,
CodeGeneratorService compiler)
Generate Java code to implement the type conversion
|
abstract java.lang.Object |
convert(ValueRepresentation value,
java.lang.Class targetClass,
XPathContext context)
Convert an XPath value to a Java value of a specified class
|
static SequenceType |
getEquivalentItemType(java.lang.Class javaClass)
Get the nearest XPath equivalent to a Java class.
