Overview
A Checkstyle configuration specifies which modules to plug in and apply to Java source files. Modules are structured in a tree whose root is the Checker module. The next level of modules contains:
Modules
A module element in the configuration XML document specifies a module identified by the element's name attribute.
Properties
Properties of a module control how the module performs its task. Each module property has a default value, and you are not required to define a property in the configuration document if the default value is satisfactory.
TreeWalker
FileSetCheck TreeWalker checks individual Java source files and defines properties that are applicable to checking such files.
TreeWalker Checks
The TreeWalker module creates a syntax tree for a Java source file and invokes its submodules, called Checks, during a walk, or traversal, of the nodes of the tree. Every node of the syntax tree has a token. A visit to a node during the traversal triggers all Checks that are configured for its token.
Severity
Each module has a severity property that a Checkstyle audit assigns to all violations of the check. The default severity level of a check is error .
tabWidth
Each module has a tabWidth property that can specify how many spaces a tab character uses. The default width by all modules is 8 spaces. Overriding the width for a parent module, will apply those changes automatically to the children. This is only used to control the spacing when violations from modules are printed.
