StringList is dynamic string array.
static method new : StringList ($array : string[])
Create a new StringList object with specific string array.
string
Internally, new array is created, and each element of argument array is copied to internal array.
If array is undef, 0-length internal array is created.
static method new_len : StringList ($length : int)
Create a new StringList object with array length.
method get : string ($index : int)
Get the value with index.
static method length : int ()
Get list length.
method insert : void ($index : int, $value : string)
Insert a element to the specific index.
method pop : string ()
Pops and returns the last value of the list, shortening the array by one element If there are no elements in the list, exception occur.
method push : void ($value : string)
Appending the value to the end of list.
method remove : string ($index : int)
Remove and return the element which is specified by the index.
method resize : void ($new_length : int)
Resize this list. If the new length is shorter than the current length, the list is truncated to the new length. If the new length is shorter than the current length, the list is truncated to the new length. If the new length is same as the current length, there is nothing to do. If the new length is longer than the current length, the list grows to the new length, and the values of the added elements are set to undef.
New length must be more than or equals to 0, otherwise a exception occur.
method set : void ($index : int, $value : string)
Set the value with index.
method set_array : void ($array : string[])
Set a array. Each elements of the array is copied to the correspoinding index of the array this list has. Note that this copy is address copy. Array must be defined, otherwise a exception occurs.
The length of argument array must be same as the length of current list array, otherwise a exception occures.
method shift : string ()
Shifts the first value of the list off and returns it, shortening the array by 1 and moving everything down. If there are no elements in the list, exception occur.
method to_array : string[] ()
Convert StringList to string array.
method unshift : void ($value : string)
Appending the value to the top of list.
