InspectionEP.enabledByDefault

getShortName

public java.lang.String getShortName()

Description copied from class: InspectionProfileEntry

buildVisitor

public PsiElementVisitor buildVisitor(ProblemsHolder holder,
                                      boolean isOnTheFly)

Description copied from class: LocalInspectionTool

Override the method to provide your own inspection visitor. Created visitor must not be recursive (e.g. it must not inherit PsiRecursiveElementVisitor) since it will be fed with every element in the file anyway. Visitor created must be thread-safe since it might be called on several elements concurrently.

Overrides:

buildVisitor in class AbstractBaseJavaLocalInspectionTool

Parameters:

holder - where visitor will register problems found.

isOnTheFly - true if inspection was run in non-batch mode

Returns:

not-null visitor for this inspection.

PsiRecursiveVisitor
