Field Detail

input

public VisualSim.actor.TypedIOPort input

Input for tokens to be a part of image blocks. This is a single port, and its type is integer matrix.

output

public VisualSim.actor.TypedIOPort output

Output for tokens. The type is inferred form the connections.

Constructor Detail

DCT8x8

public DCT8x8(VisualSim.kernel.CompositeEntity container,
java.lang.String name)
throws VisualSim.kernel.util.IllegalActionException,
VisualSim.kernel.util.NameDuplicationException

Construct an actor in the specified container with the specified name.

Parameters:
container - The container.
name - The name of this adder within the container.
Throws:
VisualSim.kernel.util.IllegalActionException - If the actor cannot be contained by the proposed container.
VisualSim.kernel.util.NameDuplicationException - If the name coincides with an actor already in the container.

Method Detail

clone

public java.lang.Object clone(VisualSim.kernel.util.Workspace workspace)
throws java.lang.CloneNotSupportedException

Override the base class to set type constraints on the ports.
Overrides:

clone in class VisualSim.actor.AtomicActor

Parameters:

workspace - The workspace into which to clone.
Returns:
A new instance of AddSubtract.
Throws:
java.lang.CloneNotSupportedException - If a derived class contains an attribute that cannot be cloned.
