DefaultIntervalModificator

public DefaultIntervalModificator()

Method Detail

isApplicable

public boolean isApplicable(TimeBarRow row,
                            de.jaret.util.date.Interval interval)

Decides whether the interval modificator is responsible for a given interval in a row.

Specified by:

isApplicable in interface IntervalModificator

Parameters:

row - row of the interval

interval - interval in question

Returns:

true if this modificator should be questioned

isSizingAllowed

public boolean isSizingAllowed(TimeBarRow row,
                               de.jaret.util.date.Interval interval)

Decide whether a given interval in a row is allowed to be sized.

Specified by:

isSizingAllowed in interface IntervalModificator

Parameters:

row - row of the interval

interval - interval in question

Returns:

true if the interval may be sized

newBeginAllowed

public boolean newBeginAllowed(TimeBarRow row,
                               de.jaret.util.date.Interval interval,
                               de.jaret.util.date.JaretDate newBegin)

Decide whether a given interval in a given row can change the begin date.

Specified by:

newBeginAllowed in interface IntervalModificator

Parameters:

row - row of the interval

interval - interval to be modified

newBegin - new begin date

Returns:

true if the modification is allowed

newEndAllowed

public boolean newEndAllowed(TimeBarRow row,
                             de.jaret.util.date.Interval interval,
                             de.jaret.util.date.JaretDate newEnd)

Decide whether a given interval in a given row can change the end date.

Specified by:

newEndAllowed in interface IntervalModificator

Parameters:

row - row of the interval

interval - interval to be modified

newEnd - new end date

Returns:

true if the modification is allowed

isShiftingAllowed
