Method Detail

convert

public Object convert(ValueRepresentation value,
                      Class targetClass,
                      XPathContext context)
               throws XPathException
Description copied from class: PJConverter
Convert an XPath value to a Java value of a specified class

Specified by:
convert in class PJConverter
Parameters:
value - the supplied XPath value
targetClass - the class of the required Java value
context - the XPath dynamic context
Returns:
the corresponding Java value, which is guaranteed to be an instance of the target class (except that an empty sequence is converted to null)
Throws:
XPathException - if the conversion is not possible or fails

compile

public String compile(String var,
                      Class targetClass,
                      CodeGeneratorService compiler)
Description copied from class: PJConverter
Generate Java code to implement the type conversion

Overrides:
compile in class PJConverter
Parameters:
var - the name of a variable whose value will be the XPath ValueRepresentation to be converted
targetClass - the required class of the Java value
compiler - provides supporting services by callback
Returns:
the text of a Java expression whose result will be a Java object/value of the required type
