Non-boolean method name must not start with question word

Reports non-boolean methods whose names start with a question word. Such method names may be confusing.

Non-boolean methods that override library methods are ignored by this inspection.

Example:

public void hasName(String name) {
  assert names.contains(name);
}

A quick-fix that renames such methods is available only in the editor.

Configure the inspection:

Use the Boolean method name prefixes list to specify the question words that should be used only for boolean methods.
Use the Ignore methods with 'java.lang.Boolean' return type option to ignore methods with java.lang.Boolean return type.
Use the Ignore methods overriding/implementing a super method option to ignore methods which have supers.
