Method Detail

saveState

public void saveState(String prefix,
             Properties properties)

Description copied from interface: IPersistable

Saves the state to the given Properties using the specified prefix. Note: The prefix must be prepended to the property key to support multiple states within one Properties instance.

Specified by:

saveState in interface IPersistable

Overrides:

saveState in class AbstractLayerTransform

Parameters:

prefix - The prefix to use for the state keys. Is also used as the state configuration name.

properties - The Properties instance to save the state to.

loadState

public void loadState(String prefix,
             Properties properties)

Description copied from class: AbstractLayerTransform

Underlying layers must load state first. If this is not done, IStructuralChangeEvent from underlying layers will reset caches after state has been loaded

Specified by:

loadState in interface IPersistable

Overrides:

loadState in class AbstractLayerTransform

Parameters:

prefix - The prefix to use for the state keys. Is also used as the state configuration name.

properties - The Properties instance to load the state from.

isColumnIndexHidden

public boolean isColumnIndexHidden(int columnIndex)

Description copied from class: AbstractColumnHideShowLayer

Will check if the column at the specified index is hidden or not. Checks this layer and also the sublayers for the visibility. Note: As the ColumnGroupModel.ColumnGroups are created index based, this method only works correctly with indexes rather than positions.

Specified by:

isColumnIndexHidden in class AbstractColumnHideShowLayer

Parameters:

columnIndex - The column index of the column whose visibility state should be checked.

Returns:

true if the column at the specified index is hidden, false if it is visible.

getHiddenColumnIndexes

public Collection<Integer> getHiddenColumnIndexes()

Description copied from class: AbstractColumnHideShowLayer

Will collect and return all indexes of the columns that are hidden in this layer. Note: It is not intended that it also collects the column indexes of underlying layers. This would cause issues on calculating positions as every layer is responsible for those calculations itself.

Specified by:

getHiddenColumnIndexes in class AbstractColumnHideShowLayer

Returns:

Collection of all column indexes that are hidden in this layer.

hideColumnPositions

public void hideColumnPositions(Collection<Integer> columnPositions)

showColumnIndexes

public void showColumnIndexes(Collection<Integer> columnIndexes)

showAllColumns

public void showAllColumns()
