public class SLReadArgumentNode
extends SLExpressionNode

Reads a function argument. Arguments are passed in as an object array.

Arguments are not type-specialized. To ensure that repeated accesses within a method are specialized and can, e.g., be accessed without unboxing, all arguments are loaded into local variables

Method Details

executeGeneric

public Object executeGeneric(com.oracle.truffle.api.frame.VirtualFrame frame)

Description copied from class: SLExpressionNode

The execute method when no specialization is possible. This is the most general case, therefore it must be provided by all subclasses.
