Method Detail

isInside

static boolean isInside(@Nullable
                        LocalDate aStart,
                        boolean bInclStart,
                        @Nullable
                        LocalDate aEnd,
                        boolean bInclEnd,
                        @Nonnull
                        LocalDate aQuery)

Check if the provided query date is between start and end. A null start means "since forever". A null end means "until eternity and beyond".

Parameters:

aStart - Start date. May be null.

bInclStart - true if "start date" = "query date" should be a match, false if not.

aEnd - End date may be null.

bInclEnd - true if "end date" = "query date" should be a match, false if not.

aQuery - Date to query whether it is inside or not. May not be null.

Returns:

true if query date ≥ start date and ≤ end date

isInPeriod

default boolean isInPeriod(boolean bInclBoundaries,
                           @Nonnull
                           LocalDate aDate)

Check if the provided date is inside this period, assuming that start and end are included in/part of the range.

Parameters:

bInclBoundaries - true if "start date" = "query date" should be a match i.e. if "end date" = "query date" should be a match, false if this should not be a match.

aDate - Date to check. May not be null.

Returns:

true if it is contained, false otherwise.

Since:

10.0.0

isInPeriodIncl

default boolean isInPeriodIncl(@Nonnull
                               LocalDate aDate)

Check if the provided date is inside this period, assuming that start and end are included in/part of the range.

Parameters:

aDate - Date to check. May not be null.

Returns:

true if it is contained, false otherwise.

Since:

8.6.5

isNowInPeriodIncl

default boolean isNowInPeriodIncl()

isInPeriodExcl

default boolean isInPeriodExcl(@Nonnull
                               LocalDate aDate)

Check if the provided date is inside this period, assuming that start and end are excluded from/not part of the range.

Parameters:

aDate - Date to check. May not be null.

Returns:

true if it is contained, false otherwise.

isNowInPeriodExcl

default boolean isNowInPeriodExcl()

hasOverlap

static boolean hasOverlap(@Nullable
                          LocalDate aStart1,
                          @Nullable
                          LocalDate aEnd1,
                          @Nullable
                          LocalDate aStart2,
                          @Nullable
                          LocalDate aEnd2,
                          boolean bInclBoundaries)

Check if the provided range 1 has an overlap with the provided range 2.

Parameters:

aStart1 - Start date of the first range. May be null.

aEnd1 - End date of the first range. May be null meaning it's validity is "until eternity and beyond".

aStart2 - Start date of the second range. May be null.

aEnd2 - End date of the second range. May be null meaning it's validity is "until eternity and beyond".

bInclBoundaries - true if "start date" = "query date" should be a match i.e. if "end date" = "query date" should be a match, false if this should not be a match.

Returns:

true if the 2 ranges have at least one point in time (with duration 0) that they share.
