    • resetDefaults

      public static void resetDefaults()
      It resets the static defaults for the standard representation.

      The following defaults will be reapplied:

      • maxElementsForPrinting = 1000

    • setMaxLengthForSingleLineDescription

      public static void setMaxLengthForSingleLineDescription(int value)

    • getMaxLengthForSingleLineDescription

      public static int getMaxLengthForSingleLineDescription()

      public static int getMaxStackTraceElementsDisplayed()

    • setMaxStackTraceElementsDisplayed

      public static void setMaxStackTraceElementsDisplayed(int value)

    • getMaxElementsForPrinting

      public static int getMaxElementsForPrinting()

    • 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

      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.

      toStringOf in interface Representation
      Parameters:
      object - the given object.
      Returns:
      the toString representation of the given object.

    • unambiguousToStringOf

      public String unambiguousToStringOf(Object obj)
      Returns the String representation of the given object with its type and hexadecimal identity hash code so that it can be differentiated from other objects with the same toStringOf(Object) representation.
      Specified by:
      unambiguousToStringOf in interface Representation
      Parameters:
      obj - the object to represent.
      Returns:
      the unambiguous toString representation of the given object.

      protected boolean hasAlreadyAnUnambiguousToStringOf(Object obj)
      Determine whether the given object's type has a representation that is not ambiguous.
      Parameters:
      obj - the object to check
      Returns:
      true if the given object's type has a representation that is not ambiguous, false otherwise.

    • fallbackToStringOf

      protected String fallbackToStringOf(Object object)
      Returns the String representation of the given object. This method is used as a last resort if none of the StandardRepresentation predefined string representations were not called.
