Annotation Type Subst

@Retention(CLASS) @Target({METHOD,FIELD,LOCAL_VARIABLE,PARAMETER}) public @interface Subst
Specifies the replacement value for non-constant variables and method return values. This may help static analyzers to properly parse the concatenation of several values which is used in @Language or Pattern context.

Example: 

@Subst("Tahoma")
final String font = new JLabel().getFont().getName();

@Language("HTML")
String message = "<html><span style='font: " + font + "; font-size:smaller'>"
  + ... + "</span></html>";

Here the parser assumes that when font appears in the concatenation it's value is "Tahoma", so it can continue parsing the concatenation.
