public class BitsToInt
- extends SDFConverter
This actor converts a sequence of BooleanTokens into a single IntToken.
The number of Boolean tokens is specified by the numberOfBits
parameter and should be a positive integer not larger than 32. Let k
denotes the value of the numberOfBits parameter. The output
integer is ranged from -2k to 2k - 1.
The first boolean token received indicates the sign of the integer. If
it is "false", the output integer is a non-negative number. If it is "true",
the output integer is a negative number. The least significant bit is
the last boolean token received.

numberOfBits
public Parameter numberOfBits
- The number of bits that is converted to the output integer.
It should be a positive integer no more than 32.
BitsToInt
public BitsToInt(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.
attributeChanged
public void attributeChanged(Attribute attribute)
throws IllegalActionException
- If the argument is the numberOfBits parameter, then
set the production rate of the output port.
- Overrides:
attributeChanged
in class NamedObj
- Parameters:
attribute
- The attribute that has changed.
- Throws:
IllegalActionException
- If the parameter is out of range.
fire
public final void fire()
throws IllegalActionException
- Consume numberOfBits BooleanTokens on the input.
Output a single IntToken which is representing by the
BooleanTokens.
The first token consumed is the most significant bit (The sign bit).
The last token consumed is the least significant bit
- Specified by:
fire
in interface Executable
- Overrides:
fire
in class AtomicActor
- Throws:
IllegalActionException
- If there is no director.
