Interface IGridLinePolicy

All Superinterfaces:

IPolicy

All Known Implementing Classes:

DefaultGridLinePolicy, TimeGranularityGridLinePolicy

public interface IGridLinePolicy
extends IPolicy

The grid line policy controls the behaviour of the major and minor grid lines. In general the GridLayer is capable of displaying either the minor grid lines, or the major grid lines or both at the same time. Usually the major grid lines are located on top of a minor grid lines. Depending on the dateline model however there might be situations where this is not the case (e.g. the TimeGranularityDatelineModel showing major grid lines for months and minor grid lines for 14 days). In these cases it is favourable to not show the major grid lines at all. This kind of logic can be expressed by the grid line policy.

Method Detail

isMajorGridLinesVisible

boolean isMajorGridLinesVisible(IDatelineModel model,
                                GridLineMode mode)

Determines whether the grid lines for the major time units will be shown or not.

Parameters:

model - the dateline model currently used by the dateline

mode - the grid mode (show no grid, minor grid, major grid, combined grid)

Returns:

TRUE if the grid lines for the major time unit are visible

Parameters:

model - the dateline model currently used by the dateline

mode - the grid mode (show no grid, minor grid, major grid, combined grid)

Returns:

TRUE if the grid lines for the minor time unit are visible
