All Implemented Interfaces:

EventHandler

public class MatrixModel
extends Object
implements EventHandler

A model container for BFS data files. This class is primarily intended to be used when parsing small data files. It is not recommended to use this class with large files since it may use too much memory.

After parsing data is available as

Method Detail

handleEvent

public <T> void handleEvent(EventType<T> eventType,
                            T eventData,
                            BfsParser parser)

Description copied from interface: EventHandler

The method is called by the parser when it has found something interesting in a BFS file. See the respective parser documentation for documentation about the events that it generates. There is usually some kind of information associated with the event. This information is sent to the event handler as an object. The parser should document what kind of information it sends so that event handler implementation can react and use the information.

It is recommended that event handlers ignore event types they don't know about.

Specified by:

handleEvent in interface EventHandler

Parameters:

eventType - The type of event. See the parser documentation for more information about the event types it generates

eventData - The data that is associated with the event

parser - The parser that is resposible for parsing the file

addRow

public void addRow(String... row)

Add a row of data to the model. The number of array elements in the array should be the same as the number of columns.

getColumnCount

public int getColumnCount()

Get the number of columns.

getRowCount

public int getRowCount()

Get the number of rows.

getData

public String getData(int rowIndex,
                      int colIndex)

Get the data element at a given row and column index.

Parameters:

rowIndex - The row index, a value between 0 and getRowCount()-1

colIndex - The column index, a value between 0 and getColumnCount()-1

Returns:

The data at the given location

getRowByIndex

public String[] getRowByIndex(int rowIndex)
