table
public Parameter table
- The code table. Its value is a token of type ArrayToken.
The array provides the symbol values to produce on the output.
The number of values in this array must be at least
2wordLength, or an exception
will be thrown. The number of tokens consumed by this actor when
it fires is log2(tableSize), where
tableSize is the length of the table. If all of these
values are false, then the first array entry is produced
as an output. If only the first one is true, then then second
array value is produced. In general, the N inputs consumed
are taken to be a binary digit that indexes the array,
where the first input is taken to be the low-order bit of the array.
The default code table has two entries, -1.0
and 1.0, so that input false values are mapped to -1.0,
and input true values are mapped to +1.0.
wordLength
public Parameter wordLength
- The word length is the number of boolean inputs that are consumed
to construct an index into the table. Its value is an IntToken,
with default value one.
_wordLength
private int _wordLength
_table
private Token[] _table
LineCoder
public LineCoder(CompositeEntity container,
java.lang.String name)
throws NameDuplicationException,
IllegalActionException
- Construct an actor with the given container and name.
- Parameters:
container
- The container.name
- The name of this actor.
- Throws:
IllegalActionException
- If the actor cannot be contained
by the proposed container.
NameDuplicationException
- If the container already has an
actor with this name.
clone
public java.lang.Object clone(Workspace workspace)
throws java.lang.CloneNotSupportedException
- Clone the actor into the specified workspace. This calls the
base class and then resets the type constraints.
- Overrides:
clone
in class AtomicActor
- Parameters:
workspace
- The workspace for the new object.
- Returns:
- A new actor.
- Throws:
java.lang.CloneNotSupportedException
- If a derived class contains
an attribute that cannot be cloned.- See Also:
NamedObj.exportMoML(Writer, int, String)
,
NamedObj.setDeferringChangeRequests(boolean)
fire
public void fire()
throws IllegalActionException
- Consume the inputs and produce the corresponding symbol.
- Specified by:
fire
in interface Executable
- Overrides:
fire
in class AtomicActor
- Throws:
IllegalActionException
- If a runtime type error occurs.
preinitialize
public void preinitialize()
throws IllegalActionException
- Set up the consumption constant.
- Specified by:
preinitialize
in interface Initializable
- Overrides:
preinitialize
in class AtomicActor
- Throws:
IllegalActionException
- If the length of the table is not
a power of two.
