All Methods Instance Methods Abstract Methods Concrete Methods Deprecated Methods
Modifier and Type	Method	Description
`abstract boolean`	`appliesToClassName(String name)`	Deprecated.
`protected void`	`checkNodeAndReport(Object data, Node location, Node expr)`	Deprecated. Checks whether the given expression is a equality/relation expression that compares with a size() call.
