[<Android.Runtime.Register("remove", "(Ljava/lang/Object;Ljava/lang/Object;)Z", "GetRemove_Ljava_lang_Object_Ljava_lang_Object_Handler:Java.Util.Concurrent.IConcurrentMapInvoker, Mono.Android, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null")>]

Parameters

key

Object

key with which the specified value is associated

value

Object

value expected to be associated with the specified key

Attributes

RegisterAttribute

Exceptions

UnsupportedOperationException

ClassCastException

Remarks

Removes the entry for a key only if currently mapped to a given value. This is equivalent to, for this map:

{@code
            if (map.containsKey(key)
                && Objects.equals(map.get(key), value)) {
              map.remove(key);
              return true;
            } else {
              return false;
            }}

except that the action is performed atomically.
