Interface CacheableTableModel

All Superinterfaces:

TableModel

All Known Implementing Classes:

AbstractDatabaseTableModel, CachedListTableModel, CachedTableModel, DefaultDatabaseTableModel, DefaultPivotTableModel, DistinctDatabaseTableModel, MSAccessPivotTableModel

public interface CacheableTableModel
extends TableModel

CacheableTableModel defines methods for retrieving the non-cached data of a TableModel. This is achieved by specifying the range of rows we want to retrieve.

Method Summary

List	getUncachedRows(int from, int to) Retrieves the rows from the table model by specifying a row interval.
boolean	isCountCached() Determines whether the row count has been evaluated.
boolean	isRangedModel() Determines whether the cache model can fetch data in ranges.
boolean	isValueCached(int row, int column) Determines whether the value at the specified cell has been evaluated.

Method Detail

getUncachedRows

List getUncachedRows(int from,
                     int to)

Retrieves the rows from the table model by specifying a row interval. The following condition must be true: from >= to. The List returned must contain the row elements starting at from. However, the List may contain less elements than those specified in the range.

Parameters:

from - the starting row

to - the ending row

Returns:

a list of objects, each element of which contains a row from the table model

isCountCached

boolean isCountCached()

Determines whether the row count has been evaluated.

Returns:

true if the model's row count has already been evaluated.

isValueCached

boolean isValueCached(int row,
                      int column)

Determines whether the value at the specified cell has been evaluated.

Parameters:

row - the cell's row index

column - the cell's column index

Returns:

true if the cell value at (row, column) has already been evaluated.

isRangedModel

boolean isRangedModel()

Determines whether the cache model can fetch data in ranges.

Returns:

true if the cache model can fetch ranged data.
