Method Detail

getNegativeInfinity

public static <T> Bound<T> getNegativeInfinity()

Create a new negative infinity of the desired type.

Returns:

an object of type Bound that is smaller than all elements of T.

getPositiveInfinity

public static <T> Bound<T> getPositiveInfinity()

Create a new positive infinity of the desired type.

Returns:

an object of type Bound that is greater than all elements of T.

newInstance

public static <T> Bound<T> newInstance(T base)

Creates a new bound at the specified value.

Parameters:

base - base value used for comparison.

comparatorWithInfinity
