public class DotNetObjectValue
extends ObjectValue

Method Detail

convertPrimitive

public ConversionResult convertPrimitive(BuiltInAtomicType requiredType,
                                boolean validate,
                                XPathContext context)

Convert to target data type

Overrides:

convertPrimitive in class ObjectValue

Parameters:

requiredType - the required atomic type. This must either be a primitive type, or a built-in type derived from the same primitive type as this atomic value.

validate - true if validation is required. If set to false, the caller guarantees that the value is valid for the target data type, and that further validation is therefore not required. Note that a validation failure may be reported even if validation was not requested.

context - The conversion context to be used. This is required at present only when converting to xs:Name or similar types: it determines the NameChecker to be used.

Returns:

the result of the conversion, if successful. If unsuccessful, the value returned will be a ValidationFailure. The caller must check for this condition. No exception is thrown, instead the exception information will be encapsulated within the ValidationFailure.

getItemType

public ItemType getItemType(TypeHierarchy th)

Determine the data type of the expression

Overrides:

getItemType in class ObjectValue

Parameters:

th - the type hierarchy cache

Returns:

Type.OBJECT
