Methods

Clear()

Removes all of the mappings from this map (optional operation).

Compute(Object, IBiFunction)
ComputeIfAbsent(Object, IFunction)
ComputeIfPresent(Object, IBiFunction)
ContainsKey(Object)

Returns true if this map contains a mapping for the specified key.

ContainsValue(Object)

Returns true if this map maps one or more keys to the specified value.

CopyOf(IDictionary)

Returns an "#unmodifiable">unmodifiable Map containing the entries of the given Map.

Disposed() (Inherited from IJavaPeerable)
DisposeUnlessReferenced() (Inherited from IJavaPeerable)
Entry(Object, Object)

Returns an immutable Entry containing the given key and value.

EntrySet()

Returns a Set view of the mappings contained in this map.

Equals(Object)

Compares the specified object with this map for equality.

Finalized() (Inherited from IJavaPeerable)
ForEach(IBiConsumer)

Performs the given action for each entry in this map until all entries have been processed or the action throws an exception.

Get(Object)

Returns the value to which the specified key is mapped, or null if this map contains no mapping for the key.

GetHashCode()

Returns the hash code value for this map.

GetOrDefault(Object, Object)

Returns the value to which the specified key is mapped, or defaultValue if this map contains no mapping for the key.

KeySet()

Returns a Set view of the keys contained in this map.

Merge(Object, Object, IBiFunction)

If the specified key is not already associated with a value or is associated with null, associates it with the given non-null value.

Of()

Returns an immutable map containing zero mappings.

Of(Object, Object)

Returns an immutable map containing a single mapping.

Of(Object, Object, Object, Object)

Returns an immutable map containing two mappings.

OfEntries(IMapEntry[])

Returns an immutable map containing keys and values extracted from the given entries.

Put(Object, Object)

Associates the specified value with the specified key in this map (optional operation).

PutAll(IDictionary)

Copies all of the mappings from the specified map to this map (optional operation).

PutIfAbsent(Object, Object)

If the specified key is not already associated with a value (or is mapped to null) associates it with the given value and returns null, else returns the current value.

Remove(Object)

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

Remove(Object, Object)

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

Replace(Object, Object)
Replace(Object, Object, Object)
ReplaceAll(IBiFunction)

Replaces each entry's value with the result of invoking the given function on that entry until all entries have been processed or the function throws an exception.
