The $string must be defined. Otherwize an exception is thrown.
utf8_length
static method utf8_length : int ($string : string)
Gets the length as a UTF-8 string from the $string, and returns it.
Exceptions:
The $string must be defined. Otherwize an exception is thrown.
If the $string contains an invalid Unicode code point, an exception is thrown.
Examples:
# 3
my $utf8_length = Fn->utf8_length("あいう");
utf8_substr
static method utf8_substr : string ($string : string, $utf8_offset : int, $utf8_length : int = -1);
Gets the substring from the $string. The extracting range of the string is from the $utf8_offset to the position proceeded by the $utf8_length, and returns it.
If the length is less than 0, the length to the end of the string is calculated from the length of the $string and the $utf8_offset.
Exceptions:
The $string must be defined. Otherwize an exception is thrown.
If the $string contains an invalid Unicode code point, an exception is thrown.
The $utf8_offset + the $utf8_length must be less than or equal to the UTF-8 length of the $string. Otherwize an exception is thrown.
Examples:
# "いえ"
my $utf8_substr = Fn->utf8_substr("あいうえ", 1, 2);
merge_options
static method merge_options : object[] ($options1 : object[], $options2 : object[]);
Creates a new any object array merging the $options1 and the $options2, and returns it.
If the $options2 contains the same key of the $options1, the key of the $options1 is overwritten by the key of $options2.
Exceptions:
The $options1 must be defined. Otherwise an exception is thrown.
The $options2 must be defined. Otherwise an exception is thrown.
The length of the $options1 must be an even number. Otherwise an exception is thrown.
The length of the $options2 must be an even number. Otherwise an exception is thrown.
The key of the $options1 must be defined. Otherwise an exception is thrown.
The key of the $options1 must be the string type. Otherwise an exception is thrown.
The key of the $options2 must be defined. Otherwise an exception is thrown.
The key of the $options2 must be the string type. Otherwise an exception is thrown.
Exceptions of the Hash class can be thrown.
Examples:
my $merged_options = Fn->merge_options({foo => 1, bar => 2}, {baz => 5});
object_to_int
static method object_to_int : int ($object : object);
Converts the address of the $object to a value of the int type, and returns it.

Returns the version number of the SPVM language.
get_version_number
static method get_version_number : double ($class_name : string);
Returns the version number of a class.
Exceptions:
The $class_name must be defined. Otherwise an exception is thrown.
The class specified by the $class_name must be loaded. Otherwise an exception is thrown.
