How to use the eltype method with CircularDeque in Julia
Programming Bytes
Overview
The eltype method is used to get the type of items of the CircularDeque object.
Note: The
CircularDeque objectobject is a double-ended queue implementation using a circular buffer of fixed capacity (while creating the deque, the capacity should be provided). It supports insertion and deletion on both ends.
Syntax
eltype!deque_object)
Julia eltype function syntax
Parameter
This method takes a CircularDeque object and the values to be inserted as arguments.
Return value
This method returns the data type of the elements of the CircularDeque object.
Example
using DataStructures
#create a new CircularDeque object for 5 elements
deque = CircularDeque{Int}(5);
push!(deque,2);
push!(deque, 3);
push!(deque, 4);
println("\nDeque -> $(deque)")
# print the data type of the elements of the deque
println("\nDeque -> $(eltype(deque))")Using the eltype method to get the datatype of the CircularDeque elements
Explanation
- Line 4: We create a
CircularDequeobject with the name,deque. For this object, we set the capacity as5, meaning it can hold 5 elements. Also, we set the elements ofdequeto be an integer datatype. - Lines 6–8: We add three integer elements,
2,3, and4, todequeusing thepush!method. - Line 13: We use the
eltypemethod to get the datatype of thedequeelements. We getInt64as a result.
