Field Detail

THE_INSTANCE

public static StringConverter.IdentityConverter THE_INSTANCE
Constructor Detail

StringConverter.IdentityConverter

public StringConverter.IdentityConverter()
Method Detail

convert

public ConversionResult convert(AtomicValue input)
Description copied from class: Converter
Convert an atomic value from the source type to the target type

Overrides:
convert in class StringConverter
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 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.

convertString

public ConversionResult convertString(CharSequence input)
Description copied from class: StringConverter
Convert a string to the target type of this converter.

Specified by:
convertString in class StringConverter
Parameters:
input - the string to be converted
Returns:
either an AtomicValue of the appropriate type for this converter (if conversion succeeded), or a ValidationFailure if conversion failed.

isAlwaysSuccessful

public boolean isAlwaysSuccessful()
Description copied from class: Converter
Ask if this converter will always succeed

Overrides:
isAlwaysSuccessful in class Converter
Returns:
true if this Converter will never return a ValidationFailure

validate

public ValidationFailure validate(CharSequence input)
Description copied from class: StringConverter
Validate a string for conformance to the target type, without actually performing the conversion

Overrides:
validate in class StringConverter
Parameters:
input - the string to be validated
Returns:
null if validation is successful, or a ValidationFailure indicating the reasons for failure if unsuccessful
