Interface ELLambdaBody

All Known Subinterfaces:
ELLambdaBody.Binary, ELLambdaBody.Nullary, ELLambdaBody.Ternary, ELLambdaBody.Unary
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface @Internal public interface ELLambdaBody
The compiled body of a Jakarta Expression Language lambda expression.

The parameters of the lambda expression are the parameters of the body, so that the generated code reads them as Java locals rather than through ELContext.getLambdaArgument(String). The nested interfaces are the forms the generated code implements, one per arity up to three, the general form takes the arguments as an array.
