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).

6.5.0

Method Detail

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.
