Class DotSite

java.lang.Object
  orc.runtime.values.Value
      orc.runtime.sites.Site
          orc.runtime.sites.DotSite

All Implemented Interfaces:

Callable, TraceableValue

Direct Known Subclasses:

BoundedBuffer.BufferInstance, Buffer.BufferInstance, Cell.CellInstance, Datasite, FieldProxy, Ref.RefInstance, Semaphore.SemaphoreInstance, SyncChannel.SyncChannelInstance, TupleValue

public abstract class DotSite
extends Site
implements TraceableValue

Dot-accessible sites should extend this class and declare their Orc-available methods using addMembers(). The code is forward-compatible with many possible optimizations on the field lookup strategy. A dot site may also have a default behavior which allows it to behave like a normal site. If its argument is not a message, it displays that default behavior, if implemented. If there is no default behavior, it raises a type error.
