Interface IntIndexMap<E>

Type Parameters:

E - the element type

All Superinterfaces:

Collection<E>, Iterable<E>, ToIntFunction<E>

All Known Implementing Classes:

IntIndexHashMap

public interface IntIndexMap<E>
extends Iterable<E>, ToIntFunction<E>, Collection<E>

A map which is indexed by integer value and thus acts similarly to a set.

Method Detail

containsKey

boolean containsKey(int index)

Determine whether the given index is contained in the map.

Parameters:

index - the index

Returns:

true if it is contained in the map

get

E get(int index)

Get the value for the given index.

Parameters:

index - the index

Returns:

the corresponding value

removeKey

E removeKey(int index)

Remove and return a value for the given index.

Parameters:

index - the index

Returns:

the value

put

E put(E value)

Put a value into the map, replacing and returning any existing mapping.

Parameters:

value - the value to add

Returns:

the old value, or null if the old value was null or was not present

remove

boolean remove(Object o)

Specified by:

remove in interface Collection<E>

putIfAbsent

E putIfAbsent(E value)

Put a value into the map if there is not already an existing mapping for it.

Parameters:

value - the value to add

Returns:

the existing value, if any, or null if the existing value was null or the value was added successfully

computeIfAbsent

E computeIfAbsent(int key,
                  IntFunction<E> producer)

Compute a map value if no mapping exists.

Parameters:

key - the key

producer - the producer which creates a new value

Returns:

the existing or new value

replace

E replace(E value)

Put a value into the map only if there is an existing mapping for it.

Parameters:

value - the value to store

Returns:

the previous value (may be null) or null if there was no mapping to replace

replace

boolean replace(E oldValue,
                E newValue)

Replace an old value with a new value.

Parameters:

oldValue - the value to replace

newValue - the value to replace with

Returns:

true if the replacement succeeded, or false if the old value was not present in the map
