Method Detail

natural

public static <T> ElementOrderMethod<T> natural()

Get the natural ordering method

Type Parameters:

T - the element type

Returns:

the natural ordering method

internal

public static <T> ElementOrderMethod<T> internal()

Get the internal ordering method. This represents the method of explicitly maintaining a map from the elements to long integers. Thus, it incurs a penalty in space and in lookups.

Type Parameters:

T - the element type

Returns:

the internal ordering method

comparator

public static <T> ElementOrderMethod<T> comparator(java.util.Comparator<T> comparator)

Get the comparator ordering method.

Type Parameters:

T - the element type

Parameters:

comparator - the actual comparator

Returns:

the comparator ordering method

guavaComparator

public static <T> ElementOrderMethod<T> guavaComparator()

Get the guava comparator ordering method.

Type Parameters:

T - the element type

Returns:

the comparator ordering method

comparator

public java.util.Comparator<T> comparator()

Get the comparator. Returns null if the method does not use an explicit comparator.

Returns:

the comparator or null if the method does not use an explicit comparator

getType

public ElementOrderMethod.Type getType()

Get the type

Returns:

the type
