Method Details

convert
Description copied from class:Converter
Convert an atomic value from the source type to the target type- Overrides:
convert
in classStringConverter
- Parameters:
input
- the atomic value to be converted, which the caller guarantees to be of the appropriate type for the converter- Returns:
- the result of the conversion, as an
AtomicValue
, if conversion succeeds, or aValidationFailure
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.
-
convertString
Description copied from class:StringConverter
Convert a string to the target type of this converter.- Specified by:
convertString
in classStringConverter
- Parameters:
input
- the string to be converted- Returns:
- either an
AtomicValue
of the appropriate type for this converter (if conversion succeeded), or aValidationFailure
if conversion failed.
-
isAlwaysSuccessful
public boolean isAlwaysSuccessful()Description copied from class:Converter
Ask if this converter will always succeed- Overrides:
isAlwaysSuccessful
in classConverter
- Returns:
- true if this Converter will never return a ValidationFailure
-
validate
Description copied from class:StringConverter
Validate a string for conformance to the target type, without actually performing the conversion- Overrides:
validate
in classStringConverter
- Parameters:
input
- the string to be validated- Returns:
- null if validation is successful, or a ValidationFailure indicating the reasons for failure if unsuccessful
