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.

Specific commands or tools from the interface will be identified as follows:

Select the Save button.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "We can include other contexts through the use of the include directive."

A block of code is set as follows:

INFO  [org.jboss.as] (Controller Boot Thread) WFLYSRV0025: WildFly Full 10.1.0.Final (WildFly Core 2.2.0.Final) started in 20718ms - Started 580 of 816 services (405 services are lazy, passive or on-demand)

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

asyncInvoker.get(new InvocationCallback<Response>() {
   @Override
   public void completed(Response response) {
    ...

Any command-line input or output is written as follows:

vi $USER_HOME/.bash_profile

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Clicking the Next button moves you to the next screen."
