properties
Description copied from interface:ObjectConverter
Returns the manner in which source values (S) are mapped to target values (T). Some possible function properties are:- Injective if no pair of S can produce
the same T value (e.g.: conversions from
Integer
toString
). - Surjective if every values of T can be
created from one or many values of S (e.g.: conversions from
String
toInteger
). - Bijective if there is a one-to-one relationship between the S and T values.
- Order preserving if any sequence of
increasing S values (in the sense of
Comparable
) is mapped to a sequence of increasing T values. - Order reversing if any sequence of
increasing S values (in the sense of
Comparable
) is mapped to a sequence of decreasing T values.

method returnsnull
for unconvertible source values, then this properties set cannot containFunctionProperty.INJECTIVE
because more than one source value could be converted to the samenull
target value.- Specified by:

in interfaceObjectConverter<Locale,

- the manners in which source values are mapped to target values. May be an empty set, but never null.

getSourceClass
Description copied from interface:ObjectConverter
Returns the type of objects to convert.- Specified by:
getSourceClass
in interfaceObjectConverter<Locale,
PT_Locale> - Returns:
- the type of objects to convert.

getTargetClass
Description copied from interface:ObjectConverter
Returns the type of converted objects.- Specified by:

in interfaceObjectConverter<Locale,

- the type of converted objects.

apply
Description copied from interface:ObjectConverter
Converts the given object from the source type S to the target type T. If the given object cannot be converted, then this method may either returnsnull
or throws an exception, at implementation choice (except for injective functions, which must throw an exception - see the class Javadoc for more discussion about function properties).Example: in Apache SIS implementation, converters fromString
toNumber
distinguish two kinds of unconvertible objects:- Null or empty source string result in a
null
value to be returned. - All other kind of unparsable strings results in an exception to be thrown.
""
value is unconvertible but nevertheless considered as part of the converter domain, and is mapped to "no number". All other unparsable strings are considered outside the converter domain. - Null or empty source string result in a

inverse
Description copied from interface:ObjectConverter
Returns a converter capable to convert instances of T back to instances of S. Before to invoke this method, callers can verify if this converter is invertible as below:- Specified by:
inverse
in interfaceObjectConverter<Locale,
PT_Locale> - Returns:
- a converter for converting instances of T back to instances of S.
