Pattern Format
The patterns in this book follow a single template format so they are easier to read in succession. Some patterns will omit some of the sections if they don’t make sense in the context of that pattern.
- Intent
-
This section is a quick description of the problem the pattern is intended to solve.
- Motivation
-
This section explains why you would want to solve this problem or where it would appear. Some use cases are typically discussed in brief.
- Applicability
-
This section contains a set of criteria that must be true to be able to apply this pattern to a problem. Sometimes these are limitations in the design of the pattern and sometimes they help you make sure this pattern will work in your situation.
