Conventions

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

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "You can also run the server using the same command line by typing mvn exec:exec once the installation is done."

A block of code is set as follows:

public class RuleFlowProcessInstance implements ProcessInstance {
  public RuleFlowProcess getRuleFlowProcess() { ... }
  public int getState() { ... }
  public void setVariable(String name, Object value) { ... }
  public Collection<NodeInstance> getNodeInstances() { ... }
  public Object getVariable(String name) { ... }
}

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

TaskService taskService = HumanTaskServiceFactory.
        newTaskServiceConfigurator().
        entityManagerFactory(emf).
        userGroupCallback(ugCallback).
        interceptor(priority, new UserLogInterceptor()).
        getTaskService();

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

bin/standalone.sh --server-config=standalone-full.xml

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "Once the Finish button is clicked on, we're directed to the project editor, where we can configure dependencies, KIE bases, KIE sessions, and all the project-relevant components."
