apply
public void apply(CallContext ctx) throws Throwable
Description copied from class:Expression
Evaluate the expression. This is named apply rather than eval so it is compatible with the full-tail-call calling convention, and we can stash an Expression in CallContext's proc field. FIXME - are we making use of this?- Overrides:
apply
in classExpression
- Throws:
Throwable
