Class DeclaredReturnFrame

java.lang.Object

dev.frostlake.executor.DeclaredReturnFrame

public final class DeclaredReturnFrame
extends Object

The declared RETURNS type of the procedure whose body is running, with the block and compound depths its body started at — what tells a RETURN written directly in that body (the one live converts to the declared type) from one nested in an IF, a loop, a handler or an inner block (kept as it is). A CALL pushes a frame and puts the caller's back afterwards, so nested calls each see their own.
