public static java.lang.String toString(@Nullable
                                                 java.lang.Object o)

An improved version of String.valueOf(Object).

Objects are converted to strings in a Java-like format:

Character:

'\n'

Byte, Short, Long, Float, Double:

3B 3S 3L 3F 3D

String:

"abc\n"
"abcdef"... (123 chars)

Other CharSequence:

StringBuilder "abc\n"

Char array:

char[4] 'abc\n'
char[99] 'abcdef'...

Other array:

int[3] { 1, 2, 3 }
short[199] { 1, 2, 3, 4, 5, 6, ... }

Nested array:

Object[3][] { [self], null, Object[2] { "abc", [parent] } }

Any other object:

The string returned by Object.toString()

Large objects are abbreviated with an ellipsis as shown above:

Char array:

CHAR_ARRAY_ELLIPSIS chars

Other array:

ARRAY_ELLIPSIS elements

CharSequence:

CHAR_SEQUENCE_ELLIPSIS chars

As the result string exceeds TOTAL_LENGTH_ELLIPSIS characters, all remaining arrays and CharSequences are abbreviated, so the result string will effectively not be much longer than TOTAL_LENGTH_ELLIPSIS characters.
