All Implemented Interfaces:

Serializable, SwingConstants

public class IlvHourTimeScaleRow
extends IlvBasicTimeScaleRow

This class implements methods from the parent class IlvBasicTimeScaleRow to provide a complete scale displaying hourly intervals. By default, it displays each hourly interval with a text formatted using a java.text.SimpleDateFormat created with the "HH" string. The exact result depends on the time scale Locale, in English "20" for 8:12:34 PM. By default, the text is centered on the interval.

Constructor Detail

IlvHourTimeScaleRow

public IlvHourTimeScaleRow()

This constructor creates and initializes an IlvHourTimeScaleRow object.

Method Detail

setHourStep

public void setHourStep(int value)

Sets the number of hours for an interval. It should be both a positive number and a divisor of 24.

Parameters:

value - The number of hours for a scale interval.

getHourStep

public int getHourStep()

Returns the number of hours in an interval. The default is 1.

Returns:

The number of hours for a scale interval.

createTimeIncrementPolicy

protected IlvTimeIncrementPolicy createTimeIncrementPolicy()

Creates the time increment policy for the row. The policy will determine the time increments used by the row for tick marks and labeling. This method returns an instance of IlvTimeIncrementPolicy.Hour.

Specified by:

createTimeIncrementPolicy in class IlvBasicTimeScaleRow

Returns:

The time increment policy.

Since:

JViews 7.5

IlvBasicTimeScaleRow.getTimeIncrementPolicy()

computeDateText

protected String computeDateText(Date time)

Computes and returns the text that should be drawn for the interval beginning at the specified time. The row's current DateFormat is used to format the time. IlvBasicTimeScaleRow.invalidateDateTextCache() must be invoked whenever a row property changes which affects how this method formats the text.

Overrides:

computeDateText in class IlvBasicTimeScaleRow

Parameters:

time - The start time of the scale interval.

Returns:

The formatted text for the specified interval.
