Registers new formatter for the given type. All instances of the given type will be formatted with the provided formatter.

Type Parameters:

T - the type to register a formatter for

Parameters:

type - the class of the type to register a formatter for

formatter - the formatter

removeAllRegisteredFormatters

public static void removeAllRegisteredFormatters()

Clear all formatters registered per type with registerFormatterForType(Class, Function).

toStringOf

public String toStringOf(Object object)

Returns standard the toString representation of the given object. It may or not the object's own implementation of toString.

Specified by:
