    • IntRange

      public IntRange(int min, int max)
      Create a new range instance.
      Parameters:
      min - the minimum value of the range
      max - the maximum value of the range
      Throws:
      IllegalArgumentException - if min > max

    • IntRange

      public IntRange(int value)
      Create a new (half-open) range, which contains only the given value: [value, value + 1).
      Parameters:
      value - the value of the created (half-open) integer range

  • Method Details

    • contains

      public boolean contains(int value)
      Checks whether the given value is within the range [min, max).
      Parameters:
      value - the value to check
      Returns:
      true if the value is with the range [min, max), false otherwise
      Since:
      8.0

    • intersect

      public Optional<IntRange> intersect(IntRange other)
      Return the intersection of this range with the other.
      Parameters:
      other - the intersection range or Optional.empty() if there is none
      Returns:
      the range intersection
      Since:
      8.0

    • size

      public int size()
      Return the size of the IntRange: max - min.
      Returns:
      the size of the int range
      Since:
      3.9

    • stream

      public IntStream stream()
      Returns a sequential ordered IntStream from min() (inclusive) to max() (exclusive) by an incremental step of 1.

      An equivalent sequence of increasing values can be produced sequentially using a for loop as follows: 

      for (int i = range.min(); i < range.max(); ++i) {
    // ...
}
      Returns:
      a sequential IntStream for the range of int elements
      Since:
      3.4

    • toString

      public String toString()
      Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.
      Specified by:
      toString in class Record
      Returns:
      a string representation of this object

    • hashCode

      public final int hashCode()
      Returns a hash code value for this object. The value is derived from the hash code of each of the record components.
      Specified by:
      hashCode in class Record
      Returns:
      a hash code value for this object

    • equals

      public final boolean equals(Object o)
      Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with the compare method from their corresponding wrapper classes.
      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
      Returns:
      true if this object is the same as the o argument; false otherwise.

    • min

      public int min()
      Returns the value of the min record component.
      Returns:
      the value of the min record component

    • max

      public int max()
      Returns the value of the max record component.
      Returns:
      the value of the max record component
