Constructor Detail

ExternalTextEffigy

public ExternalTextEffigy(Workspace workspace)

Create a new effigy in the specified workspace with an empty string for its name.

Parameters:

workspace - The workspace for this effigy.

ExternalTextEffigy

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

Create a new effigy in the given directory with the given name.

Parameters:

container - The directory that contains this effigy.

name - The name of this effigy.

Throws:

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

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

Method Detail

attributeChanged

public void attributeChanged(Attribute attribute)
                      throws IllegalActionException

If the argument is the identifier parameter, then tell the external editor to finally open the file specified by the identifier (as opposed to at newTextEffigy(container, text) time at which the document file is not yet specified. This greatly simplifies the interaction with the external text editor: instead of first telling it to create a text buffer with some name and no file attached, the buffer, its associated file name, and any text saved by newTextEffigy(container, text) is given to the text editor in one transaction. NOTE: This depends on TextEditorTableau.createTableau(effigy) setting the identifier expression after newTextEffigy(container, text).

Overrides:

attributeChanged in class Effigy

Parameters:

attribute - The attribute that changed.

Throws:

IllegalActionException - If the base class throws it.

newTextEffigy

public static TextEffigy newTextEffigy(CompositeEntity container,
                                       java.lang.String text)
                                throws java.lang.Exception

Create a new effigy in the given container containing the specified text. The new effigy will have a new instance of DefaultStyledDocument associated with it.

Parameters:

container - The container for the effigy.

text - The text to insert in the effigy.

Returns:

A new instance of TextEffigy.

Throws:

java.lang.Exception - If the text effigy cannot be contained by the specified container, or if the specified text cannot be inserted into the document.

newTextEffigy

public static TextEffigy newTextEffigy(CompositeEntity container,
                                       java.net.URL base,
                                       java.net.URL in)
                                throws java.lang.Exception

Create a new ExternalTextEffigy.

Parameters:

container - The container for the effigy.

base - The base for relative file references, or null if there are no relative file references. This is ignored in this class.

in - The input URL, or null if there is none.

Returns:

A new instance of TextEffigy.

Throws:

java.lang.Exception - If the URL cannot be read, or if the data is malformed in some way.

setModifiable

public void setModifiable(boolean flag)

Pass the modifiable flag onto the external text editor.

Overrides:

setModifiable in class Effigy

Parameters:

flag - False to prevent writing to the URI.

See Also:

Effigy.masterEffigy(), Effigy.isModifiable(), Effigy.isModified(), Effigy.setModified(boolean)

show

public void show()

Signal the external text editor to (re)display its buffer associated with this effigy.
