Constructor Detail

AbstractInterval

public AbstractInterval(E left,
                        E right)

AbstractInterval

public AbstractInterval(E left,
                        E right,
                        boolean bLeftClosed,
                        boolean bRightClosed,
                        boolean bReverse)

Method Detail

checkArgs

private void checkArgs(E left,
                       E right)

getLeftEndpoint

public E getLeftEndpoint()

Specified by:

getLeftEndpoint in interface IInterval<E extends java.lang.Comparable<E>,ME extends AbstractInterval<E,ME>>

Returns:

The left endpoint of this interval where the left <= right

getRightEndpoint

public E getRightEndpoint()

Specified by:

getRightEndpoint in interface IInterval<E extends java.lang.Comparable<E>,ME extends AbstractInterval<E,ME>>

Returns:

The right endpoint of this interval where the left <= right

isLeftClosed

public boolean isLeftClosed()

Specified by:

isLeftClosed in interface IInterval<E extends java.lang.Comparable<E>,ME extends AbstractInterval<E,ME>>

Returns:

True if this interval includes the left endpoint. E.g., x >= foo indicates a left-closed interval starting with and including foo. Conversely, x > foo is said to be left-open because the interface starts with, but excludes foo i.e., there is no minimum value defined in the interval, rather the interval is open with foo as the limit of minimum values.

isRightClosed

public boolean isRightClosed()

Specified by:

isRightClosed in interface IInterval<E extends java.lang.Comparable<E>,ME extends AbstractInterval<E,ME>>

Returns:

True if this interval includes the right endpoint. E.g., x <= foo indicates a right-closed interval ending with and including foo. Conversely, x < foo is said to be right-open because the interface ends with, but excludes foo i.e., there is no maximum value defined in the interval, rather the interval is open with foo as the limit of maximum values.

contains

public boolean contains(E e)

Specified by:

contains in interface IInterval<E extends java.lang.Comparable<E>,ME extends AbstractInterval<E,ME>>

Parameters:

e - An element to test

Returns:

True if elem is a proper element in the set of elements defining this interval.

contains

public boolean contains(ME interval)

Specified by:

contains in interface IInterval<E extends java.lang.Comparable<E>,ME extends AbstractInterval<E,ME>>

Parameters:

interval - An interval to test for containment

Returns:

True if interval's endpoints are proper elements in the set of elements defining this interval.

isReverse

public boolean isReverse()

Specified by:

isReverse in interface IInterval<E extends java.lang.Comparable<E>,ME extends AbstractInterval<E,ME>>

Returns:

True if this interval iterates from the right by default e.g., if the interval is specified in reverse order: 10..1, Gosu will create a reverse intervall
