Overloads

Remove(Object)

Removes the mapping for a key from this map if it is present (optional operation).

[Android.Runtime.Register("remove", "(Ljava/lang/Object;)Ljava/lang/Object;", "GetRemove_Ljava_lang_Object_Handler:Java.Util.IMapInvoker, Mono.Android, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null")]
public Java.Lang.Object? Remove (Java.Lang.Object? key);
[<Android.Runtime.Register("remove", "(Ljava/lang/Object;)Ljava/lang/Object;", "GetRemove_Ljava_lang_Object_Handler:Java.Util.IMapInvoker, Mono.Android, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null")>]
abstract member Remove : Java.Lang.Object -> Java.Lang.Object

Parameters

key
Object

key whose mapping is to be removed from the map

Returns

Object

the previous value associated with key, or null if there was no mapping for key.

Attributes
RegisterAttribute

Exceptions

UnsupportedOperationException

if removing from this Map is not supported.

Remarks

Removes the mapping for a key from this map if it is present (optional operation). More formally, if this map contains a mapping from key k to value v such that Objects.equals(key, k), that mapping is removed. (The map can contain at most one such mapping.)

Returns the value to which this map previously associated the key, or null if the map contained no mapping for the key.

If this map permits null values, then a return value of null does not necessarily indicate that the map contained no mapping for the key; it's also possible that the map explicitly mapped the key to null.

The map will not contain a mapping for the specified key once the call returns.
