* A wrapper around java.util.Collection that implements java.util.Set. This class keeps a pointer to the

|
* Collection and does not persist any data on its own.
|
||
|
|
*
|
||
|
|
* Useful when you need a Set but creating a HashSet is too expensive.
|
||
|
|
*
|
||
|
|
* IMPORTANT: The elements of the Collection *must* be unique! This class does not check.
|

* @hide Only a subset of ICU is exposed in Android
