public class ArrayRemoveElement
extends TypedAtomicActor

Remove occurrences of a specified element from an array. This actor reads an array from the array input port and an element from the element port-parameter and removes all occurances that match the element from the array. The output may be an empty array, in which case it will have the same type as the input.

Field Detail

array

public TypedIOPort array

Input array. The type of this port is at least an array of the type of the element port.

output

public TypedIOPort output

The resulting output array. Note that the output will be a new array with the same type as the input array.

element

public PortParameter element

The element to be removed.

Constructor Detail

ArrayRemoveElement

public ArrayRemoveElement(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.

Method Detail

clone

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

Override the base class to set type constraints.

Overrides:

clone in class TypedAtomicActor

Parameters:

workspace - The workspace for the cloned object.

Returns:

A new ComponentEntity.

Throws:

java.lang.CloneNotSupportedException - If cloned ports cannot have as their container the cloned entity (this should not occur), or if one of the attributes cannot be cloned.

NamedObj.exportMoML(Writer, int, String), NamedObj.setDeferringChangeRequests(boolean)

fire

public void fire()
          throws IllegalActionException

If there is an array input, consume it and create a new array that contains all elements of the input that are not equal to the value given by the element port-parameter.

Specified by:

fire in interface Executable

Overrides:

fire in class AtomicActor<TypedIOPort>

Throws:

IllegalActionException - Not thrown in this base class.

wrapup

public void wrapup()
            throws IllegalActionException

Clear port parameter value.

Specified by:

wrapup in interface Initializable

Overrides:

wrapup in class AtomicActor<TypedIOPort>

Throws:

IllegalActionException - Not thrown in this base class.
