Examples of macromedia.asc.semantics.Slot

macromedia.asc.semantics.Slot
A slot gives a compile-time description of an operation. This includes: - type of the resulting value - expected types of the operands - var_index if used to access a particular variable - objValue, value, or intValue if used to store a constant value - method_id if used to identify a native method or operation - call_seq used to invoke @author Jeff Dyer
