DESCRIPTION

Unix standard library.

CLASS METHODS

copy_oarray

sub copy_oarray : object[] ($objects : object[], $cloner : SPVM::Cloner)

Copy object array. You must specify a SPVM::Cloner object to copy each element.

equals_oarray

sub sub equals_oarray : int ($objs1 : oarray, $objs2 : oarray, $equality_checker : SPVM::EqualityChecker)

Check equality of two objects. You must sepecify a SPVM::EqualityChecker object to check the equality of each element.

$objs1 and $objs2 and $equality_checker must be defined, otherwise a exception occur.

Return 1 if the length of $objs1 and $objs2 is same and all element is same, otherwise return 0.

joino

sub joino : string ($sep : string, $objects : oarray, $stringer : SPVM::Stringer)

Stringify all objects and join them by specific separator. You must specify a SPVM::Stringer object to stringify each element.

split

sub split : string[] ($sep : string, $string : string)

Split a string by the specific separator.
