SPVM::StringList - Dynamic string array
Usage
use StringList;
# Create a string list
my $list = StringList->new;
my $list = StringList->new(["abc", "def", "ghi"]);
# Create a string list
my $list = StringList->new_len(10);
# Get list length
my $length = $list->length;
# Push string value
$list->push("abc");
# Pop string value.
my $element = $list->pop;
# Unshift string value.
$list->unshift("abc");
# Shift string value.
my $element = $list->shift;
# Set string value.
$list->set(2, "abc");
# Get string value.
my $element = $list->get(2);
# Insert string value
$list->insert(1, "abc");
# Remove string value
my $element = $list->remove(1);
# Convert StringList to string array.
my $array = $list->to_array;Description
StringList is a dynamic string array.
Enumerations
enum {
DEFAULT_CAPACITY = 4,
}DEFAULT_CAPACITY
The default capacity. The value is 4.
Fields
capacity
has capacity : ro int;The capacity. This is the length of the internally reserved elements to extend the length of the list.
length
has length : ro int;The length of the list.
Class Methods
new
static method new : StringList ($array : string[] = undef, $capacity : int = -1);
Create a new StringList object using "new_len".
The passed length to "new_len" is the length of the array. If the array is undef, the length is 0.
The element's addresses of the string array are copied to the values of the the created array.
Examples:
my $list = StringList->new;
my $list = StringList->new(["abc", "def", "ghi"]);new_len
static method new_len : StringList ($length : int, $capacity : int = -1);
Creates a new StringList object with $length and $capacity.
If $capacity is less than 0, the capacity is set to the value of "DEFAULT_CAPACITY".
If $length is greater than $capacity, $capacity is set to $length.
Exceptions:
$length must be greater than or equal to 0. Otherwise an exception is thrown.
Instance Methods
get
method get : string ($index : int);
Gets the element of the position of $index.
Exceptions:
$index must be greater than or equal to 0. Otherwise an exception is thrown.
$index must be less than the length of $list. Otherwise an exception is thrown.
insert
method insert : void ($index : int, $element : string);
Inserts an $element to the position of $index.
Exceptions:
$index must be greater than or equal to 0. Otherwise an exception is thrown.
$index must be less than or equal to the length of $list. Otherwise an exception is thrown.
pop
method pop : string ();
Removes the last element and return it.
Exceptions:
The length of $list must be greater than 0. Otherwise an exception is thrown.
push
method push : void ($element : string);
Adds an $element after the end of the list.
remove
method remove : string ($index : int);
Removes the element at the position of $index and return it.
Exceptions:
$index must be greater than or equal to 0. Otherwise an exception is thrown.
$index must be less than the length of $list. Otherwise an exception is thrown.
replace
method replace : void ($offset : int, $remove_length : int, $replace : string[]);
Replaces the elements of the range specified by $offset and $lenght with $replace array.
Exceptions:
$offset must be greater than or equal to 0. Otherwise an exception is thrown.
$remove_length must be greater than or equal to 0. Otherwise an exception is thrown.
$offset + $removing lenght must be less than or equal to the length of $list.
reserve
method reserve : void ($new_capacity : int);
Reserves the elements with $new_capacity.
If $new_capacity is greater than the capacity of the list, the capacity of the list is extended to $new_capacity.
Note that "values" is replaced with the new values and the values of the original list are copied to the new values in the above case.
Exceptions:
$new_capacity must be greater than or equal to 0. Otherwise an exception is thrown.
resize
method resize : void ($new_length : int);
Resizes the list with $new_length.
Exceptions:
$new_length must be greater than or equal to 0. Otherwise an exception is thrown.
set
method set : void ($index : int, $element : string);
Sets $element at the position of $index.
Exceptions:
$index must be greater than or equal to 0. Otherwise an exception is thrown.
$index must be less than the length of $list. Otherwise an exception is thrown.
set_array
method set_array : void ($array : string[]);
Sets an $array. Each element of $array is copied to the element of the list.
Exceptions:
$array must be defined.
The length of $array must be equal to the length of $list. Otherwise an exception is thrown.
shift
method shift : string ();
Removes the first element and return it.
Exceptions:
The length of $list must be greater than 0. Otherwise an exception is thrown.
to_array
method to_array : string[] ();
Converts the list to an array.
get_array_unsafe
method get_array_unsafe : string[] ();
Gets the internally array.
This array is unsafe because it continues to point to the old array if the internal array is extended.
unshift
method unshift : void ($element : string);
Inserts an $element at the beginning of the list.
