INSTANCE

public static final FractionConverter INSTANCE

The unique instance of this converter.

Constructor Details

FractionConverter

public FractionConverter()

Creates a new converter. Only one instance is enough, but this constructor needs to be public for allowing invocation by ServiceLoader.

Method Details

unique

public ObjectConverter<Fraction,Integer> unique()

Returns the unique instance of this converter.

Overrides:

unique in class SystemConverter<Fraction,Integer>

Returns:

the unique instance of this converter.

• ObjectToString.unique()

properties

public Set<FunctionProperty> properties()

Declares that this converter is injective, surjective, invertible and preserve order.

Returns:

the properties of this bijective converter.

apply

public Integer apply(Fraction value)
              throws UnconvertibleObjectException

Converts the given fraction to an integer.

Parameters:

value - the fraction to convert.

Returns:

the given fraction as an integer.

Throws:

UnconvertibleObjectException - if the given fraction is not an integer.

inverse

public ObjectConverter<Integer,Fraction> inverse()

Returns the converter from integers to fractions.

Specified by:

inverse in interface ObjectConverter<Fraction,Integer>

Overrides:

inverse in class SystemConverter<Fraction,Integer>

Returns:

the inverse converter.
