Constructor Detail

CachableTableModel

public CachableTableModel(TableModel model)
Method Detail

getColumnName

public String getColumnName(int column)
Specified by:
getColumnName in interface TableModel
Overrides:
getColumnName in class AbstractTableModel

getColumnClass

public Class getColumnClass(int columnIndex)
Specified by:
getColumnClass in interface TableModel
Overrides:
getColumnClass in class AbstractTableModel

getCellDataAttributes

public DataAttributes getCellDataAttributes(int row,
                                            int column)
Description copied from interface: MetaTableModel
Returns the meta-attribute as Java-Object. The object type that is expected by the caller is defined in the TableMetaData property set. It is the responsibility of the implementor to map the native meta-data model into a model suitable for reporting.

Be aware that cell-level attributes do not make it into the designtime dataschema, as this dataschema only looks at the structural metadata available and does not contain any data references.

Specified by:
getCellDataAttributes in interface MetaTableModel
Parameters:
row - the row of the cell for which the meta-data is queried.
column - the index of the column for which the meta-data is queried.
Returns:
the meta-data object.

isCellDataAttributesSupported

public boolean isCellDataAttributesSupported()
Description copied from interface: MetaTableModel
Checks, whether cell-data attributes are supported by this tablemodel implementation.

Specified by:
isCellDataAttributesSupported in interface MetaTableModel
Returns:
true, if the model supports cell-level attributes, false otherwise.

getColumnAttributes

public DataAttributes getColumnAttributes(int column)
Description copied from interface: MetaTableModel
Returns the column-level attributes for the given column.

Specified by:
getColumnAttributes in interface MetaTableModel
Parameters:
column - the column.
Returns:
data-attributes, never null.

getTableAttributes

public DataAttributes getTableAttributes()
Description copied from interface: MetaTableModel
Returns table-wide attributes. This usually contain hints about the data-source used to query the data as well as hints on the sort-order of the data.

Specified by:
getTableAttributes in interface MetaTableModel
Returns:
the table-attributes, never null.

getRowCount

public int getRowCount()
Specified by:
getRowCount in interface TableModel

getColumnCount

public int getColumnCount()
Specified by:
getColumnCount in interface TableModel

getValueAt

public Object getValueAt(int rowIndex,
                         int columnIndex)
Specified by:
getValueAt in interface TableModel

isSafeToCache

public static boolean isSafeToCache(TableModel model)
