                                                                AtomicType viaType,

setNamespaceResolver

public Converter<F,T> setNamespaceResolver(NamespaceResolver resolver)

Description copied from class: Converter

Provide a namespace resolver, needed for conversion to namespace-sensitive types such as QName and NOTATION. The resolver is ignored if the target type is not namespace-sensitive

Overrides:

setNamespaceResolver in class Converter<F extends AtomicValue,T extends AtomicValue>

Parameters:

resolver - the namespace resolver to be used

Returns:

a new Converter customised with the supplied namespace context. The original Converter is unchanged (see bug 2754)

convert

public ConversionResult convert(F input)

Description copied from class: Converter

Convert an atomic value from the source type to the target type

Specified by:

convert in class Converter<F extends AtomicValue,T extends AtomicValue>

Parameters:

input - the atomic value to be converted, which the caller guarantees to be of the appropriate type for the converter. The results are undefined if the value is of the wrong type; possible outcomes are (apparent) success, or a ClassCastException.

Returns:

the result of the conversion, as an AtomicValue, if conversion succeeds, or a ValidationFailure object describing the reasons for failure if conversion is not possible. Note that the ValidationFailure object is not (and does not contain) an exception, because it does not necessarily result in an error being thrown, and creating exceptions on non-failure paths is expensive.
