Constructor Detail

IlvDataContainerDocument

public IlvDataContainerDocument()

Constructs an empty IlvDataContainerDocument.

Method Detail

initializeDocument

public boolean initializeDocument(Object userData)

Initializes a new data container document. If the specified userData is an IlvDataContainer instance, it will be associated with the document with the method setDataContainer(ilog.views.appframe.docview.project.IlvDataContainer). Otherwise, a new data container is created with the method createDataContainer(java.lang.Object) and associated with the document.

Specified by:

initializeDocument in interface IlvDocument

Overrides:

initializeDocument in class IlvAbstractDocument

Parameters:

userData - The user data to initialize the document with - can be null or an IlvDataContainer instance.

Returns:

false if the document could not create a new data container; true otherwise.

See Also:

IlvApplication.newDocument(java.lang.Object, boolean), IlvApplication.newDocument(), IlvApplication.newDocument(IlvDocumentTemplate, boolean, Object)

getDataContainer

public IlvDataContainer getDataContainer()

Returns the data container associated with this document.

Specified by:

getDataContainer in interface IlvDataContainerProvider

See Also:

setDataContainer(ilog.views.appframe.docview.project.IlvDataContainer), DATA_CONTAINER_PROPERTY

setDataContainer

public void setDataContainer(IlvDataContainer dataContainer)

Sets the data container of this document. Triggers a property change event for the DATA_CONTAINER_PROPERTY.

Parameters:

dataContainer - The new data container of the document.

See Also:

getDataContainer(), DATA_CONTAINER_PROPERTY

readDocument

                            IlvFileFilter filter)

Initializes the document data from the specified file url. By default, a reader is created from the specified URL and is given as the parameter to the readDocument(Reader, IlvFileFilter) method.

Specified by:

readDocument in interface IlvFileDocument

Overrides:

readDocument in class IlvAbstractFileDocument

createDataContainer

protected IlvDataContainer createDataContainer(Object userData)

Factory method for creating a new data container to associate with this document. By default, the method creates an instance of IlvDefaultDataContainer. It can be overridden to create other data container types.

Parameters:

userData - The user data parameter of the initializeDocument(java.lang.Object) method - can be null.

Returns:

The newly created IlvDataContainer instance.

initializeDataContainer

protected void initializeDataContainer(IlvDataContainer dataContainer,
                                       Object userData)

Initializes the specified dataContainer. This method is called when the document is initializing with the initializeDocument method and after the method createDataContainer(java.lang.Object) has been called. By default, it does nothing. It can be overridden to create a default hierarchy of data that corresponds to a document just initialized. For example, it is overridden by the IlvProjectDocument to create a project root node that corresponds to the project document.

Parameters:

dataContainer - The data container to initialize.

userData - The user data parameter of the initializeDocument(java.lang.Object) method - can be null.

See Also:

endInitializeDataContainer(ilog.views.appframe.docview.project.IlvDataContainer)

endInitializeDataContainer

protected void endInitializeDataContainer(IlvDataContainer dataContainer)

Finishes initializing the specified dataContainer. This method is called after the document and its associated data container have been initialized, whether with the initializeDocument or readDocument method. By default it does nothing. It should be overridden to finish initializing the data container of the document, whether it was initialized from a file or by default.
For example, it is overridden by the IlvProjectDocument class for adding listeners to the root node of the data container.

Parameters:

dataContainer - The data container to finish initializing.

See Also:

initializeDataContainer(ilog.views.appframe.docview.project.IlvDataContainer, java.lang.Object)

openDocument

public IlvDocument openDocument(Object node)

Opens a document associated with the specified data container node.

If a document was previously created for this node, it would be reactivated with its views. If its views have been closed, new views will be created and activated.

If no document was previously created for this node, a new one would be created, together with the views for editing it.

Parameters:

node - The node to create a document for.

Returns:

The associated document or null if a document cannot be created for the specified node.

canOpenDocument

public boolean canOpenDocument(Object node)

Determines whether a new document can be opened and associated with the specified data container node. By default, it returns true.

Returns:

true if the node can be opened; false otherwise.

areNodeDocumentsAttached

public boolean areNodeDocumentsAttached()

Determines whether the node documents are attached to the data container document.

If node documents are attached to this document, they will be closed when this document closes. Otherwise, they must be closed by the application user after this document is closed and node file documents appear in the Most Recently Used file list managed by the application.

In both modes, the application user can close the node document.

Returns:

true if the documents associated with data container nodes are attached to this document; false otherwise.

See Also:

attachNodeDocuments(boolean), IlvApplication.attachDocument(ilog.views.appframe.docview.IlvDocument, ilog.views.appframe.docview.IlvDocument), NODE_DOCUMENTS_ATTACHED_PROPERTY, attachNodeDocuments(boolean)

public void attachNodeDocuments(boolean attach)

Attaches or detaches the document created by this document for associating with the data container nodes.

Triggers a property change event for the NODE_DOCUMENTS_ATTACHED_PROPERTY.

Parameters:

attach - If true, node documents will be attached to this document. Otherwise, node documents are not attached.

See Also:

areNodeDocumentsAttached(), NODE_DOCUMENTS_ATTACHED_PROPERTY
