public class Title
extends StringParameter
implements WebExportable

Attribute specifying a title for a model or a component in a model. This attribute provides a visual title in the model, rendered more suitably for a title than a normal annotation. Moreover, if you export to web, this is used as the title for the containing component and for any exported web page. By default, the title is not shown on the web page except as part of the image of the model. If you wish for the title to also be shown in the HTML text before the image, then set the showTitleInHTML parameter to true.

Constructor Detail

Title

public Title(NamedObj container,
             java.lang.String name)
      throws IllegalActionException,
             NameDuplicationException

Create an instance of this parameter.

Parameters:

container - The container.

name - The name.

Throws:

IllegalActionException - If the superclass throws it.

NameDuplicationException - If the superclass throws it.

Method Detail

attributeChanged

public void attributeChanged(Attribute attribute)
                      throws IllegalActionException

React to a changes in the attributes by changing the icon.

Overrides:

attributeChanged in class Variable

Parameters:

attribute - The attribute that changed.

Throws:

IllegalActionException - If the change is not acceptable to this container (should not be thrown).

clone

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

Clone the object into the specified workspace.

Overrides:

clone in class Parameter

Parameters:

workspace - The workspace for the new object.

Returns:

A new AbstractTextAttribute.

Throws:

java.lang.CloneNotSupportedException - If any of the attributes cannot be cloned.

See Also:

Object.clone()

getMimeType

public java.lang.String getMimeType()

A title is of type text/html.

Specified by:

getMimeType in interface WebExportable

Returns:

The string text/html

isOverwriteable

public boolean isOverwriteable()

Return true, since new title content should overwrite old title content.

Specified by:

isOverwriteable in interface WebExportable

Returns:

True, since new title content should overwrite old title content.

moveToFirst

public int moveToFirst()
                throws IllegalActionException

Move this object to the first position in the list of attributes of the container. This overrides the base class to create an attribute named "_renderFirst" and to remove an attribute named "_renderLast", if it is present. This attribute is recognized by vergil, which then renders this attribute before entities, connections, and other attributes. This method gets write access on workspace and increments the version.

Specified by:

moveToFirst in interface Moveable

Overrides:

moveToFirst in class Attribute

Returns:

The index of the specified object prior to moving it, or -1 if it is not moved.

Throws:

IllegalActionException - If this object has no container.

moveToLast

public int moveToLast()
               throws IllegalActionException

Move this object to the last position in the list of attributes of the container. This overrides the base class to create an attribute named "_renderLast" and to remove an attribute named "_renderFirst" if it is present. This attribute is recognized by vergil, which then renders this attribute after entities, connections, and other attributes. This method gets write access on workspace and increments the version.

Specified by:

moveToLast in interface Moveable

Overrides:

moveToLast in class Attribute

Returns:

The index of the specified object prior to moving it, or -1 if it is not moved.

Throws:

IllegalActionException - If this object has no container.

provideContent

public void provideContent(WebExporter exporter)
                    throws IllegalActionException

Return a title for the model. The title can be returned as an attribute or an element, but not a document.

Specified by:

provideContent in interface WebExportable

Parameters:

exporter - The web exporter to which to write content.

Throws:

IllegalActionException - If there is a problem creating the content or setting the attribute.

_provideAttributes

protected void _provideAttributes(WebExporter exporter)
                           throws IllegalActionException

Provide a title for this object to the specified web exporter.

Parameters:

exporter - The WebExporter to add content to

Throws:

IllegalActionException - If something is wrong with the specification of the content.

validate

public java.util.Collection validate()
                              throws IllegalActionException

Override the base class to set the text to be displayed in the icon.

Specified by:

validate in interface Settable

Overrides:

validate in class Variable

Returns:

The current list of value listeners, which are evaluated as a consequence of this call to validate().

Throws:

IllegalActionException - If this variable or a variable dependent on this variable cannot be evaluated (and is not lazy) and the model error handler throws an exception. Also thrown if the change is not acceptable to the container.
