Description

StackList is a library implementing a generic, dynamic stack (linked list version) for the Arduino.

It is created to help adding LIFO (Last In - First Out) Abstract Data Structure to a program for any use.

StackList library is part of the "Data Structures & Algorithms" libraries.

Installation

Download here: StackList.zip

Put the "StackList" directory in "libraries" directory.

In the Arduino IDE, create a new sketch and select from the menubar "Sketch->Import Library->StackList".

Once the library is imported, an "#include <StackList.h>" line will appear at the top of your Sketch.

Creation

Replace "T" with the data type you want to use.

StackList <T> stack;

Create instance (object) of a StackList class.

Methods

Replace "T" with the data type you want to use.

void push (const T item)

Push an item with data type "T" to the stack.

T pop ()

Pop an item with data type "T" from the stack.

T peek ()

Get an item with data type "T" from the stack.

bool isEmpty ()

Check if the stack is empty.

int count ()

Get the number of items in the stack.

void setPrinter (Print & printer)

Sets the printer of the stack.

Examples

Swapping strings by using a generic, dynamic stack data structure.

FAQ

  • How do I use multiple stacks?

StackList is a class. Therefore to use multiple stacks, you must create an instance for each of them.
