Method Detail

resetDefaults

public static void resetDefaults()

It resets the static defaults for the standard representation.

The following defaults will be reapplied:

• maxLengthForSingleLineDescription = 80
• maxElementsForPrinting = 1000

setMaxLengthForSingleLineDescription

public static void setMaxLengthForSingleLineDescription(int value)

getMaxLengthForSingleLineDescription

public static int getMaxLengthForSingleLineDescription()

setMaxElementsForPrinting

public static void setMaxElementsForPrinting(int value)

registerFormatterForType

public static <T> void registerFormatterForType(Class<T> type,
                                                Function<T,String> formatter)

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:

toStringOf in interface Representation

Parameters:

object - the given object.

Returns:

the toString representation of the given object.

customFormat

hasCustomFormatterFor

protected boolean hasCustomFormatterFor(Object object)

unambiguousToStringOf

public String unambiguousToStringOf(Object obj)

Description copied from interface: Representation

Returns the String representation of the given object with its type and hexadecimal hash code so that it can be differentied from other objects with the same Representation.toStringOf(Object) representation.

Specified by:

Parameters:

obj - the object to represent.

Returns:

the toString representation of the given object.

fallbackToStringOf

Parameters:

o - the object that is expected to be an array.

Returns:

the String representation of the given array.
