Class VDataPacket

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.lang.Iterable<ADataPacket>, java.util.Collection<ADataPacket>, java.util.List<ADataPacket>, java.util.RandomAccess

public class VDataPacket
extends java.util.Vector<ADataPacket>

Composite data type for use in data packets: DataPacket<VDataPacket>
Note that Vector<VDataPacket> cannot be used as a data packet data type directly because type erasure prevents the distinction between Vector<A> and Vector<B> -- that is, they produce the same Class object.
Usage:

      // make the vector of data packets
      VDataPacket vdp = new VDataPacket();
      vdp.add(datapacket1);
      vdp.add(datapacket2);
      vdp.add(datapacket3);
      // etc
      // make the composite data packet
      ADataPacket vd = new DataPacket<VDataPacket>(VDataPacket.class, vdp);
 

This class is a vector of the abstract data packets, ADataPacket. If a vector of more specific types of data packets is desired, a custom class that is a sub-class of the desired Vector type should be used instead of this class. Composites made as such would be distinguishable as per their held types.

makeMapCmd

public static <R,P> ADataPacketAlgoCmd<java.util.Vector<R>,VDataPacket,P> makeMapCmd(DataPacketAlgo<R,P> algo)

Convenience method that creates a command that maps a visitor over the vector of data packets.
Since the result returned by the returned command is a vector of R, the returned command must be wrapped in another command before it can be used in a recursive algorithm, which would require a return of type R.

Type Parameters:

R - The return type of the given visitor.

P - The vararg input parameter type of the original visitor.

Parameters:

algo - The visitor to be mapped over all the stored data packets.

Returns:

An ADataPacketAlgoCmd whose results are a vector of results from applying the given visitor to each data packet element.
