  • Element Details

    • value

      String value

      The inline format string. Placeholders like $1, $2 etc can be used where the 1..n parameters of the inlined method are used for $1 to $n and the imported() types are used for subsequent indices. The next index $n can be used to insert all type parameters of the original declaration. And finally the last indices refer to the upper bound substitute of the type parameters individually.

      So the order is arguments, imports, all type parameters at once incl. brackets and upper bounds of the individual type parameters without brackets

      For the following signature
      @Inline(value=".." imported = BigDecimal.class) public void <T1, T2> myMethod(String p1, String p2)

      • $1 refers to p1
      • $2 refers to p2
      • $3 refers to BigDecimal
      • $4 refers to <T1, T2>
      • $5 refers to the upper bound of T1
      • $6 refers to the upper bound of T2

    • imported

      Class<?>[] imported
      Types that should be imported to inline the operation.
      Default:
      {}

    • statementExpression

      boolean statementExpression
      Whether the inlined expression is a statement expression (see 14.8 - Statement Expressions in Java Language Specification, Third Edition )
      Default:
      false

    • constantExpression

      boolean constantExpression
      Whether the compiled Java is a constant expression operator. (see 15.28. Constant Expressions in Java Language Specification, Third Edition
      Since:
      2.5
      Default:
      false
