Interface CtYieldStatement

  • All Superinterfaces:

    public interface CtYieldStatement
extends CtCFlowBreak
    This code element defines a yield statement. Example: 
         int x = 0;
     x = switch ("foo") {
         default -> {
                                        x=x+1;
                                        yield x; //<--- yield statement
                                        }
     };
    A yield statement is implicit in the following example: Example: 
         int x = 0;
     x = switch ("foo") {
         default -> 4; //<---  implicit yield statement
     };
    the example wouldn't be allowed without the brackets at the default case, because java syntax defines case -> [expression] or case -> [blockStatement] and yield is not a expression.

    • Method Detail

      • getExpression

        CtExpression<?> getExpression()
        Gets the expression of the yield statement. Example: case 1 -> {yield 10}; (This syntax is available as a feature since Java 14)

      • setExpression

        <T extends CtYieldStatement> T setExpression​(CtExpression<?> expression)
        Gets the expression of the yield statement. Example: case 1 -> {yield 10}; (This syntax is available as a feature since Java 14)
