    • Some

      public Some(T value)
      Creates an instance of a Some record class.
      Parameters:
      value - the value for the value record component

  • Method Details

    • hasSome

      public boolean hasSome()
      Specified by:
      hasSome in interface Maybe<T>

    • flatmap

      public <B> Maybe<B> flatmap(java.util.function.Function<? super T,Maybe<B>> mapper)
      Specified by:
      flatmap in interface Maybe<T>

    • onSome

      public Maybe<T> onSome(java.util.function.Consumer<T> onSuccess)
      Specified by:
      onSome in interface Maybe<T>

    • onNone

      public Maybe<T> onNone(Runnable onNone)

      onNone in interface Maybe<T>

    • orElse

      public T orElse(java.util.function.Supplier<T> t)
      Specified by:
      orElse in interface Maybe<T>

    • toString

      public final 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 Objects::equals(Object,Object).
      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.

    • value

      public T value()
      Returns the value of the value record component.
      Returns:
      the value of the value record component
