public class MatrixViewer
extends AbstractPlaceableActor

An actor that displays the contents of a matrix input. This actor has a single input port, which only accepts MatrixTokens. One token is consumed per firing (in postfire()). The data in the MatrixToken is displayed in a table format with scrollbars, using the swing JTable class.

Field Detail

input

public TypedIOPort input

The input port.

width

public Parameter width

The width of the table in pixels. This must contain an integer. If the table is larger than this specified width, then scrollbars will appear, or the column width is adjusted. The default value is 500.

height

public Parameter height

The height of the table in pixels. This must contain an integer. If the table is larger than this specified width, then scrollbars will appear. The default value is 300.

Constructor Detail

MatrixViewer

public MatrixViewer(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

attributeChanged

public void attributeChanged(Attribute attribute)
                      throws IllegalActionException

Notification that an attribute has changed. If the attribute is width or height then read the value of the attribute.

Overrides:

attributeChanged in class NamedObj

Parameters:

attribute - The attribute that changed.

Throws:

IllegalActionException - If the expression of the attribute cannot be parsed or cannot be evaluated.

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 removes association with graphical objects belonging to the original class.

Overrides:

clone in class AbstractPlaceableActor

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:

Object.clone()

initialize

public void initialize()
                throws IllegalActionException

Initialize this matrix viewer. If place() has not been called with a container into which to place the display, then create a new frame into which to put it.

Specified by:

initialize in interface Initializable

Overrides:

initialize in class AtomicActor<TypedIOPort>

Throws:

IllegalActionException - If the parent class throws it.

place

public void place(java.awt.Container container)

Specify the container in which the data should be displayed. An instance of JTable will be added to that container. The table is configured such that a user cannot reorder the columns of the table. Also, the table maintains a fixed preferred size, and will employ scrollbars if the table is larger than the preferred size. If this method is not called, the JTable will be placed in its own frame. The table is also placed in its own frame if this method is called with a null argument. The background of the table is set equal to that of the container (unless it is null).

Specified by:

place in interface Placeable

Specified by:

place in class AbstractPlaceableActor

Parameters:

container - The container into which to place the table.

postfire

public boolean postfire()
                 throws IllegalActionException

Consume a matrix token from the input port and display the token in a table. If a token is not available, do nothing.

Specified by:

postfire in interface Executable

Overrides:

postfire in class AtomicActor<TypedIOPort>

Returns:

True if execution can continue into the next iteration.

Throws:

IllegalActionException - If there is no director, or if the base class throws it.

setContainer

public void setContainer(CompositeEntity container)
                  throws IllegalActionException,
                         NameDuplicationException

Override the base class to remove the display from its graphical container if the argument is null.

Overrides:

setContainer in class AtomicActor<TypedIOPort>

Parameters:

container - The proposed container.

Throws:

IllegalActionException - If the base class throws it.

NameDuplicationException - If the base class throws it.

See Also:

ComponentEntity.getContainer()

setDisplayName

public void setDisplayName(java.lang.String name)

Set a name to present to the user.

If the MatrixViewer window has been rendered, then the title of the MatrixViewer window will be updated to the value of the name parameter.

Overrides:

setDisplayName in class NamedObj

Parameters:

name - A name to present to the user.

See Also:

NamedObj.getDisplayName()

setFrame

public void setFrame(javax.swing.JFrame frame)

Specify the associated frame and set its properties (size, etc.) to match those stored in the _windowProperties attribute. In this class, if the frame is null, close the tableau and set it to null. Once closed, the matrix window will not reopen unless _tableau is null.

Overrides:

setFrame in class AbstractPlaceableActor

Parameters:

frame - The associated frame.

setName

public void setName(java.lang.String name)
             throws IllegalActionException,
                    NameDuplicationException

Set or change the name. If a null argument is given the name is set to an empty string. Increment the version of the workspace. This method is write-synchronized on the workspace.

If the MatrixViewer window has been rendered, then the title of the MatrixViewer window will be updated to the value of the name parameter.

Specified by:

setName in interface Nameable

Overrides:

setName in class ComponentEntity<TypedIOPort>

Parameters:

name - The new name.

Throws:

IllegalActionException - If the name contains a period or if the object is a derived object and the name argument does not match the current name.

NameDuplicationException - Not thrown in this base class. May be thrown by derived classes if the container already contains an object with this name.

NamedObj.getName(), NamedObj.getName(NamedObj)
