Annotation Type Language

@Retention(value=CLASS)
 @Target(value={METHOD,FIELD,PARAMETER,LOCAL_VARIABLE,ANNOTATION_TYPE})
public @interface Language

Specifies that an element of the program represents a string that is a source code on a specified language. Code editors may use this annotation to enable syntax highlighting, code completion and other features inside the literals that assigned to the annotated variables, passed as arguments to the annotated parameters, or returned from the annotated methods. This annotation also could be used as a meta-annotation, to define other annotations for convenience. E.g. the following annotation could be defined to annotate the strings that represent Java methods:

   @Language(value = "JAVA", prefix = "class X{", suffix = "}")
   @interface JavaMethod {}

Element Detail

value

@NonNls
public abstract java.lang.String value

Language name like "JAVA", "HTML", "XML", "RegExp", etc. The complete list of supported languages is not specified. However, at least the following languages should be recognized:

• "JAVA" - Java programming language
• "HTML" - HTML
• "XML" - XML
• "RegExp" - Regular expression supported by Java Pattern

prefix

@NonNls
public abstract java.lang.String prefix

A constant prefix that is assumed to be implicitly added before the literal. This helps to apply proper highlighting when the program element represents only a part of the valid program. E.g. if the method parameter accepts a Java method, it could be annotated as void methodProcessor(@Language(value="JAVA", prefix="class X {", suffix="}").

Default:

""

suffix

@NonNls
public abstract java.lang.String suffix

A constant suffix that is assumed to be implicitly added after the literal. See prefix() for details.

Default:

""
