Constructor Detail

OWLResultSetTableModel

public OWLResultSetTableModel(TupleOWLResultSet results,
                              PrefixManager prefixman,
                              boolean hideUri,
                              boolean fetchAll,
                              int fetchSizeLimit)
                       throws org.semanticweb.owlapi.model.OWLException

This constructor creates a TableModel from a ResultSet. It is package private because it is only intended to be used by ResultSetTableModelFactory, which is what you should use to obtain a ResultSetTableModel

Throws:

org.semanticweb.owlapi.model.OWLException

Method Detail

isFetching

public boolean isFetching()

Returns whether the table is still being populated by SQL fetched from the result object. Called from the QueryInterfacePanel to decide whether to continue updating the result count

getTabularData

public List<String[]> getTabularData()
                              throws org.semanticweb.owlapi.model.OWLException,
                                     InterruptedException

Fetch all the tuples returned by the result set.

Throws:

org.semanticweb.owlapi.model.OWLException

InterruptedException

close

public void close()

Call this when done with the table model. It closes the ResultSet and the Statement object used to create it.

finalize

protected void finalize()

Automatically close when we're garbage collected

Overrides:

finalize in class Object

getColumnCount

public int getColumnCount()

Specified by:

getColumnCount in interface TableModel

getRowCount

public int getRowCount()

Specified by:

getRowCount in interface TableModel

getColumnName

public String getColumnName(int column)

Specified by:

getColumnName in interface TableModel

getColumnClass

public Class getColumnClass(int column)

Specified by:

getColumnClass in interface TableModel

getValueAt

public Object getValueAt(int row,
                         int column)

This is the key method of TableModel: it returns the value at each cell of the table. We use strings in this case. If anything goes wrong, we return the exception as a string, so it will be displayed in the table. Note that SQL row and column numbers start at 1, but TableModel column numbers start at 0.

Specified by:

getValueAt in interface TableModel

isCellEditable

public boolean isCellEditable(int row,
                              int column)

Specified by:

isCellEditable in interface TableModel

setValueAt

public void setValueAt(Object value,
                       int row,
                       int column)

Specified by:

setValueAt in interface TableModel

addTableModelListener

public void addTableModelListener(TableModelListener l)

Specified by:

addTableModelListener in interface TableModel

removeTableModelListener

public void removeTableModelListener(TableModelListener l)

Specified by:

removeTableModelListener in interface TableModel
