HuffmanBasic(CompositeEntity container,
java.lang.String name)
Construct an actor with the given container and name.
|
| Modifier and Type | Method and Description |
|---|---|
void |
attributeChanged(Attribute attribute)
If the attribute being changed is pmf, then verify
all the elements are positive and their sum is 1.0.
|
java.lang.Object |
clone(Workspace workspace)
Override the base class to set type constraints.
|
void |
fire()
Generate the Huffman codebook for the given pmf, and
encode the input into booleans and send them to the output port.
|
java.lang.String[] |
generateCodeBook(double[] pmf)
Generate the Huffman code book given the probability
mass function.
|
void |
initialize()
Initialize the actor by resetting the _parametersInvalid to true.
