Field Detail

_INTERNAL_REPETITIONS

protected static java.lang.String _INTERNAL_REPETITIONS

The name of the internal repetitions parameter.

_REPETITIONS

protected static java.lang.String _REPETITIONS

The name of the total repetitions parameter.

Constructor Detail

PthalesAtomicActor

public PthalesAtomicActor()
                   throws IllegalActionException,
                          NameDuplicationException

Construct an actor in the default workspace with an empty string as its name. The object is added to the workspace directory. Increment the version number of the workspace.

Throws:

IllegalActionException - If the actor cannot be contained by the proposed container.

NameDuplicationException - If the container already has an actor with this name.

PthalesAtomicActor

public PthalesAtomicActor(CompositeEntity container,
                          java.lang.String name)
                   throws NameDuplicationException,
                          IllegalActionException

Create a new actor in the specified container with the specified name. The name must be unique within the container or an exception is thrown. The container argument must not be null, or a NullPointerException will be thrown.

Parameters:

container - The container.

name - The name of this actor within the container.

Throws:

IllegalActionException - If this actor cannot be contained by the proposed container (see the setContainer() method).

NameDuplicationException - If the name coincides with an entity already in the container.

PthalesAtomicActor

public PthalesAtomicActor(Workspace workspace)
                   throws IllegalActionException,
                          NameDuplicationException

Construct an actor in the specified workspace with an empty string as a name. You can then change the name with setName(). If the workspace argument is null, then use the default workspace. The object is added to the workspace directory. Increment the version number of the workspace.

Parameters:

workspace - The workspace that will list the entity.

Throws:

IllegalActionException - If the actor cannot be contained by the proposed container.

NameDuplicationException - If the container already has an actor with this name.

Method Detail

public FloatToken[] convertReal(float[] realOut)

Convert from an array used in a JNI function to Tokens.

Parameters:

realOut - The array used in a JNI function.

Returns:

An arry of Tokens.

convertToken

public float[] convertToken(Token[] tokensIn)

Convert from Tokens to array to be used in a JNI function.

Parameters:

tokensIn - The tokens to be converted.

Returns:

The array to be used in a JNI function.

newPort

public Port newPort(java.lang.String name)
             throws NameDuplicationException

Overrides:

newPort in class TypedAtomicActor

Parameters:

name - The name for the new port.

Returns:

The new port.

Throws:

Parameters:

totalRepetitions - The array of total repetitions.

internalRepetitions - The array of internal repetitions, where an internal repetition is the loop inside the C function.

Returns:

external iteration numbers

_initialize

                                                       java.lang.String name)

Return a data structure giving the dimension data contained by a parameter with the specified name in the specified port or actor. The dimension data is indexed by dimension name and contains two integers, a value and a stride, in that order.

Parameters:

actor - The name of the actor

name - The name of the parameter

Returns:

The dimension data, or an empty array if the parameter does not exist.
