Returns:

address dimensions

getValuesInPoint

int getValuesInPoint()

Gets the count of the data columns at each point in the data model.

Returns:

count of data columns at each data point

castToArray

ArrayDataModel castToArray()

Casts the data model to array.

Returns:

array data model

castToMatrix

MatrixDataModel castToMatrix()

Casts the data model to matrix.

matrix data model

fireDataChanged

void fireDataChanged(DataModelChangeEvent event)

Fires notification that data model has changed.

Parameters:

event - data change event

dispose

void dispose()
