Method Detail

addModelListener

public void addModelListener( l)

Registers a model listener with this model. A model listener listens for changes in the availability of data and for changes in the underlying data. The view calls this method to register itself as a listener. Application developers do not need to call this method.

Parameters:

l - The listener to add.

removeModelListener

public void removeModelListener( l)

Removes a model listener from the list of listeners for this model. The view calls this method to remove itself from the list of listeners. Application developers do not need to call this method.

Parameters:

l - The listener to remove.

addDataListener

public void addDataListener(DataListener l)

Registers a data listener with this model. A data listener listens for changes that a user requests in the data, such as drilling and pivoting.

Parameters:

l - The listener to add.

removeDataListener

public void removeDataListener(DataListener l)

Removes the data listener from this model.

Parameters:

l - The listener to remove.

setDataSource

public void setDataSource(DataSource ds)

Specifies the data source for this view.

Parameters:

ds - The data source for this view.

getDataSource

public DataSource getDataSource()

Retrieves the data source for this view.

Returns:

The data source for this view. This method can return null if no data source has been specified for this view.

setDataDirector

public void setDataDirector(DataDirector dd)

Specifies the data director for this view. The data director is the part of the data source that manipulates the data.

Parameters:

dd - A DataDirector implementation that has been initialized.

getDataDirector

public DataDirector getDataDirector()

Retrieves the data director for this view. The data director is the part of the data source that manipulates the data.

Returns:

The data director for this view.

setDataAccess

public void setDataAccess(DataAccess dp)

Specifies the data access for this view. The data access is the part of the data source that feeds data to the view. It is, essentially, a cursor of data.

Parameters:

dp - An implementation of the DataAccess interface.

getDataAccess

public DataAccess getDataAccess()

Get the data access for this view. The data access is the part of the data source that feeds data to the view. It is, essentially, a cursor of data.

Returns:

The DataAccess for this view. This method can return null if no data access has been specified for this view.

setDrillingEnabled

public void setDrillingEnabled(boolean b)

Specifies whether drilling is allowed in this view.

Parameters:

b - true to enable drilling, false to disable drilling.

isDrillingEnabled

public boolean isDrillingEnabled()

Indicates whether drilling is allowed in this view.

Returns:

true if drilling is enabled, false if not.
