overlapping-date-ranges - A Java Overlapping Verificator

overlapping-date-ranges is a library to centralize and help people dealing with overlapping date ranges verifications!

Compatibility

• Requires JDK 1.8 or higher;

Adding overlapping-date-ranges to your build

To add a dependency on overlapping-date-ranges using Maven, use the following:

<dependency>
  <groupId>com.github.mawippel</groupId>
  <artifactId>overlapping-date-ranges</artifactId>
  <version>1.0.5</version>
</dependency>

To add a dependency using Gradle:

dependencies {
  implementation 'com.github.mawippel:overlapping-date-ranges:1.0.5'
}

Examples

Using LocalDate

In this case, the toCompare period overlaps the comparable one, so, it returns true as it's overlapping.

LocalDate comparableInit = LocalDate.of(2019, 05, 01);
LocalDate comparableEnd = LocalDate.of(2019, 05, 05);
LocalDate toCompareInit = LocalDate.of(2019, 05, 03);
LocalDate toCompareEnd = LocalDate.of(2019, 05, 10);

boolean isOverlap = OverlappingVerificator.isOverlap(comparableInit, comparableEnd, toCompareInit, toCompareEnd);

Using LocalDateTime

In this case, the toCompare time period overlaps the comparable one, so, it returns true as it's overlapping.

LocalDateTime comparableInit = LocalDateTime.of(2019, 05, 05, 9, 10);
LocalDateTime comparableEnd = LocalDateTime.of(2019, 05, 05, 10, 15);
LocalDateTime toCompareInit = LocalDateTime.of(2019, 05, 05, 10, 00);
LocalDateTime toCompareEnd = LocalDateTime.of(2019, 05, 05, 11, 00);

boolean isOverlap = OverlappingVerificator.isOverlap(comparableInit, comparableEnd, toCompareInit, toCompareEnd);

Exceptions

If some of the end dates is before of the initial dates, a DateTimeException will be thrown, as shown bellow

LocalDate comparableInit = LocalDate.of(2019, 05, 02);
LocalDate comparableEnd = LocalDate.of(2019, 05, 03);
LocalDate toCompareInit = LocalDate.of(2019, 05, 05);
LocalDate toCompareEnd = LocalDate.of(2019, 05, 04);
OverlappingVerificator.isOverlap(comparableInit, comparableEnd, toCompareInit, toCompareEnd);

The behavior for the LocalDateTime's method is the same.
