public Immutables()

Method Details

immutableListConvert

public static <T> List<T> immutableListConvert(Collection<? extends T> source)

Converts a Collection to an immutable List by copying it.

Parameters:

source - the collection to convert

Returns:

a copied/converted immutable list

immutableTypedProperties

public static TypedProperties immutableTypedProperties(TypedProperties properties)

Creates an immutable copy of the properties.

Parameters:

properties - the TypedProperties to copy

Returns:

the immutable copy

immutableListWrap

public static <T> List<T> immutableListWrap(T... array)

Wraps an array with an immutable list. There is no copying involved.

Parameters:

array - the array to wrap

Returns:

a list containing the array

immutableListAdd

public static <T> ImmutableListCopy<T> immutableListAdd(List<T> list,
 int position,
 T element)

immutableListReplace

public static <T> ImmutableListCopy<T> immutableListReplace(List<T> list,
 int position,
 T element)

immutableListRemove

public static <T> List<T> immutableListRemove(List<T> list,
 int position)

immutableSetWrap

public static <T> Set<T> immutableSetWrap(Set<? extends T> set)

Wraps a set with an immutable set. There is no copying involved.

Parameters:

set - the set to wrap

Returns:

an immutable set wrapper that delegates to the original set

immutableMapWrap

public static <K,
V> Map<K,V> immutableMapWrap(Map<? extends K,? extends V> map)

Wraps a map with an immutable map. There is no copying involved.

Parameters:

map - the map to wrap

Returns:

an immutable map wrapper that delegates to the original map
