compareFromValue

public int compareFromValue(Object value)

compareTo

public int compareTo(AbstractRange<? extends Object> range)

Specified by:

compareTo in interface Comparable<AbstractRange<? extends Object>>

protected AbstractRange<?> createNew(Object from,
                         Object to)

equals

public boolean equals(Object other)

Overrides:

equals in class Object

expand

public AbstractRange<?> expand(AbstractRange<?> range)

Create an expanded range if the this range and the other overlap or touch

Parameters:

range -

Returns:

expand

public AbstractRange<?> expand(Object value)

Create an expanded range to include the specified value if possible.

• If the range contains this value return this instance.
• If the value = from - 1 return a new range from value-to
• If the value = to + 1 return a new range from from-value
• Otherwise return null as it is not a consecutive range

Parameters:

hashCode

public int hashCode()

Overrides:

hashCode in class Object

iterator

public Iterator<V> iterator()

Specified by:

iterator in interface Iterable<V>

next

public V next(Object value)

previous

public V previous(Object value)

size

public long size()

toList

public List<V> toList()

toString
