Constructor.

Parameters:

table - a table

column - a column

Method Detail

getLayout

public Layout getLayout()

Returns the layout object managed by this visualization or null if the visualization computes the layout by itself.

Overrides:

getLayout in class DefaultVisualization

Returns:

the layout object managed by this visualization or null.

getName

public String getName()

Returns the column name.

Specified by:

getName in interface Column

Specified by:

getName in class ColumnProxy

Returns:

the column name.

getPreferredSize

public Dimension getPreferredSize(Visualization vis)

Computes and return the preferred size for this layout and this visualization.

Specified by:

getPreferredSize in interface Layout

Parameters:

vis - the visualization

the preferred size for this layout and this visualization.

getColumn

public Column getColumn()

Returns the visualized column.

Returns:

the visualized column.

setColumn

public boolean setColumn(Column column)

Sets the visualized column.

Parameters:

column - the column
