SYNOPSYS
use SPVM::Hash;
# Book Data
my $book = SPVM::Hash->new;
$book->set_int(id => 4);
$book->set(name => "Perl");
$book->set_int(price => 300);
my $id = (int)$book->get_int("id");
my $name = (string)$book->get("name");
my $price = (int)$book->get_int("price");
# Create Book data with array
my $book = SPVM::Hash->newa([(object)id => 4, name => "Perl"]);
# Option Data
my $opt = SPVM::Hash->new;
$opt->set_int(limit => 10);
$opt->set(caption => "Perl is Good Plain Old Language");
$opt->set_double(rate => 0.95);DESCRIPTION

STATIC METHODS
new
sub new : SPVM::Hash ()Create a new SPVM::Hash object.
newa
sub newa : SPVM::Hash ($key_values : oarray)Create a new SPVM::Hash object with array.
# Create Book data with object array
my $book = SPVM::Hash->newa([(object)id => 4, name => "Perl"]);
# Create Book data with string array
my $book = SPVM::Hash->newa([foo => "4px", bar => "5px"]);INSTANCE METHODS
count
count : int ($self : self)Count keys.
copy
copy : SPVM::Hash ($self : self)Copy hash.
This is not deep copy. Address of keys and values is copied into new hash.
delete
delete : object ($self : self, $key : string)Delete a key value pair. Deleted value is returned.
exists
exists : int ($self : self, $key : string)Specify the key and check if the value exists. If exists, return 1, otherwise 0.
keys
keys : string[] ($self : self)Get keys. This method do not copy the strings.
values
values : object[] ($self : self)Get values.
get
get : object ($self : self, $key : string)Get a value.
get_byte
get_byte : byte ($self : self, $name : string)Set value with a key. the value is converted to byte type.
