Annotation Type Syntax

@Documented
 @TypeQualifier(applicableTo=String.class)
 @Retention(value=RUNTIME)
public @interface Syntax

This annotation a value that is of a particular syntax, such as Java syntax or regular expression syntax. This can be used to provide syntax checking of constant values at compile time, run time checking at runtime, and can assist IDEs in deciding how to interpret String constants (e.g., should a refactoring that renames method x() to y() update the String constant "x()").

• "Java"
• "RegEx"
• "JavaScript"
• "Ruby"
• "Groovy"
• "SQL"
• "FormatString"

Syntax names can be followed by a colon and a list of key value pairs, separated by commas. For example, "SQL:dialect=Oracle,version=2.3". Tools should ignore any keys they don't recognize.
