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)
