Everyday Data Structures

Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Each chapter of this book will also include a case study, or similar code example, that will be broken down and detailed to explain how the data structure is applied.  As such, this book is full of code examples.

A block of code is set as follows:

    public boolean isEmpty()
    {
        return this._commandStack.empty();
    }

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

    func canAddUser(user: EDSUser) -> Bool 
    { 
        if (_users.contains(user)) 
        { 
            return false; 
        } else {
            return true; 
    }
