Interface EndpointDescriptor

All Superinterfaces:
EndpointType
All Known Implementing Classes:
Endpoint, EndpointDescriptors
public interface EndpointDescriptor extends EndpointType
Interface for a handler that describes the properties of an end point of Range. An endpoint can be either a lower or upper end point, it can be closed or open, and it can have a bound or not. Unbounded end points describe negative or positive infinity and are used for open or half-open ranges such as (-Infinity, +Infinity).

  • Method Details

    • getBoundType

      com.google.common.collect.BoundType getBoundType()
      Specified by:
      getBoundType in interface EndpointType
      Returns:
      Whether the interval end is open or closed.

    • getDirection

      EndpointDirection getDirection()
      Specified by:
      getDirection in interface EndpointType
      Returns:
      Whether the interval end is a lower or upper end.

    • hasBound

      boolean hasBound()
      Returns:
      Whether this end point has a bound with an associated point object, or is unbounded (negative or positive infinity).

    • isLowerPoint

      default boolean isLowerPoint()
      Returns:
      Whether the end point is a lower end point.

    • isUpperPoint

      default boolean isUpperPoint()
      Returns:
      Whether the end point is an upper end point.

    • toAcessor

      default <C extends Comparable> EndpointAccessor<C,C> toAcessor()
      Converts this descriptor into an end point accessor for a given point object.
      Type Parameters:
      C - Type of the end points of a Range.
      Returns:
      An end point accessor with the properties of this descriptor.

    • toEndpoint

      default <C extends Comparable> Endpoint<C> toEndpoint(C point)
      Type Parameters:
      C - Type of the end points of a Range.
      Parameters:
      point - An end point object to use.
      Returns:
      An end point with the properties of this descriptor and the given point object.
