Modifier and Type	Method	Description

- Method Detail
  - appliesToWidget
```
boolean appliesToWidget(Widget widget)
```
    Checks whether or not this selector applies to the given widget.
    
    Parameters:
    
    widget - the widget to test.
    
    Returns:
    
    true if this selectors applies to the given widget, false otherwise.
  - getSpecificity
```
int getSpecificity()
```
    Returns the specificity of this selector.
    The specificity allows to determine in which order the rules of a stylesheet should be applied.
    A specificity is composed of four numbers (defined by CSS2 specification):
    
    count 1 if the declaration is from is a 'style' attribute rather than a rule with a selector, 0 otherwise (= a)
    
    count the number of ID attributes in the selector (= b)
    
    count the number of other attributes and pseudo-classes in the selector (= c)
    
    count the number of widget names and pseudo-widgets in the selector (= d)
    
    Concatenating the four numbers a-b-c-d (in a number system with a large base) gives the specificity. In this implementation, each number is stored on a byte in an integer. SelectorHelper provides a method to compute the specificity of a selector.
    Returns:
    
    the specificity of this selector.
  - equals
```
boolean equals(@Nullable
               java.lang.Object obj)
```
    Overrides:
    
    equals in class java.lang.Object
