SPVM::IO::Handle is the SPVM's IO::Handle class for I/O handling.
Usage
use IO::Handle;
my $handle = IO::Handle->new;
$handle->set_autoflush(1);Instance Methods
Fields
fd
has fd : protected int;A file descriptor.
autoflush
has autoflush : rw byte;input_line_number
has input_line_number : int;The current line number of an input file.
opened
has opened : ro protected int;Blocking
has Blocking : rw protected int;Class methods
new
static method new : IO::Handle ($options : object[]);Instance Methods
init
method init : void ($options : object[] = undef);input_line_number
method input_line_number : long ();Gets ""input_line_number" field.
This method is planed to be implemented in a child class.
This method always throws an exception.
Excepsions:
Not implemented.set_input_line_number
method set_input_line_number : void ($input_line_number : long);Sets ""input_line_number" field.
This method is planed to be implemented in a child class.
This method always throws an exception.
Excepsions:
Not implemented.close
method close : int ();eof
method eof : int ();opened
method opened : int ();If the return value of "fileno" is greater than -1, returns 1. Otherwise returns 0.
fileno
method fileno : int ();Gets "fh" field.
getc

method flush : int ();ungetc
method ungetc : int ($c : int);printflush
method printflush : int ($string : string);truncate
method truncate : int ($legnth : long);Truncates to a size of precisely length bytes.
This method is planed to be implemented in a child class.
