Description copied from class: AtomicCoercionPlan

Promote an atomic value to the required atomic type. This handles, for example, decimal to string conversion or base64Binary to hexBinary. It also handles down-casting to derived atomic types. The default implementation returns the supplied value unchanged.

Overrides:

promote in class AtomicCoercionPlan

Parameters:

atom - the untyped atomic value to be converted

requiredType - the required atomic type

request - details of the coercion request for diagnostics

Returns:

the converted atomic value

Throws:

XPathException - if conversion fails
