Method Detail

compare

public int compare(java.lang.Comparable left,
                   java.lang.Comparable right)

Specified by:

compare in interface java.util.Comparator<java.lang.Comparable>

Specified by:

compare in class Ordering<java.lang.Comparable>

reverse

public <S extends java.lang.Comparable> Ordering<S> reverse()

Description copied from class: Ordering

Returns the reverse of this ordering; the Ordering equivalent to Collections.reverseOrder(Comparator).

Overrides:

reverse in class Ordering<java.lang.Comparable>

min

public <E extends java.lang.Comparable> E min(E a,
                                              E b)

Description copied from class: Ordering

Returns the lesser of the two values according to this ordering. If the values compare as 0, the first is returned.

Implementation note: this method is invoked by the default implementations of the other min overloads, so overriding it will affect their behavior.

Overrides:

min in class Ordering<java.lang.Comparable>

Parameters:

a - value to compare, returned if less than or equal to b.

b - value to compare.

min

public <E extends java.lang.Comparable> E min(E a,
                                              E b,
                                              E c,
                                              E... rest)

Description copied from class: Ordering

Returns the least of the specified values according to this ordering. If there are multiple least values, the first of those is returned.

Overrides:

min in class Ordering<java.lang.Comparable>

Parameters:

a - value to compare, returned if less than or equal to the rest.

b - value to compare

c - value to compare

rest - values to compare

min

public <E extends java.lang.Comparable> E min(java.util.Iterator<E> iterator)

Description copied from class: Ordering

Returns the least of the specified values according to this ordering. If there are multiple least values, the first of those is returned. The iterator will be left exhausted: its hasNext() method will return false.

Overrides:

min in class Ordering<java.lang.Comparable>

Parameters:

iterator - the iterator whose minimum element is to be determined

min

public <E extends java.lang.Comparable> E min(java.lang.Iterable<E> iterable)

Description copied from class: Ordering

Returns the least of the specified values according to this ordering. If there are multiple least values, the first of those is returned.

Overrides:

min in class Ordering<java.lang.Comparable>

Parameters:

iterable - the iterable whose minimum element is to be determined

max

public <E extends java.lang.Comparable> E max(E a,
                                              E b)

Description copied from class: Ordering

Returns the greater of the two values according to this ordering. If the values compare as 0, the first is returned.

Implementation note: this method is invoked by the default implementations of the other max overloads, so overriding it will affect their behavior.

Overrides:

max in class Ordering<java.lang.Comparable>

Parameters:

a - value to compare, returned if greater than or equal to b.

b - value to compare.

max

public <E extends java.lang.Comparable> E max(E a,
                                              E b,
                                              E c,
                                              E... rest)

Description copied from class: Ordering

Returns the greatest of the specified values according to this ordering. If there are multiple greatest values, the first of those is returned.

Overrides:

max in class Ordering<java.lang.Comparable>

Parameters:

a - value to compare, returned if greater than or equal to the rest.

b - value to compare

c - value to compare

rest - values to compare

max

public <E extends java.lang.Comparable> E max(java.util.Iterator<E> iterator)

Description copied from class: Ordering

Returns the greatest of the specified values according to this ordering. If there are multiple greatest values, the first of those is returned. The iterator will be left exhausted: its hasNext() method will return false.

Overrides:

max in class Ordering<java.lang.Comparable>

Parameters:

iterator - the iterator whose maximum element is to be determined

max

public <E extends java.lang.Comparable> E max(java.lang.Iterable<E> iterable)

Description copied from class: Ordering

Returns the greatest of the specified values according to this ordering. If there are multiple greatest values, the first of those is returned.

Overrides:

max in class Ordering<java.lang.Comparable>

Parameters:

iterable - the iterable whose maximum element is to be determined

readResolve

private java.lang.Object readResolve()

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
