AbstractMap
Provides a skeletal implementation of the read-only Map interface.
The implementor is required to implement entries property, which should return read-only set of map entries.
Since Kotlin
1.1Parameters
the type of map keys. The map is invariant in its key type.
the type of map values. The map is covariant in its value type.

Functions
Returns true
if the map contains the specified key.
Returns true
if the map maps one or more keys to the specified value.
Returns a single list of all elements yielded from results of transform function being invoked on each entry of original map.
Returns a single list of all elements yielded from results of transform function being invoked on each entry of original map.
Appends all elements yielded from results of transform function being invoked on each entry of original map, to the given destination.
Appends all elements yielded from results of transform function being invoked on each entry of original map, to the given destination.
Returns the value to which the specified key is mapped, or defaultValue if this map contains no mapping for the key.
Returns the value for the given key or throws an exception if there is no such key in the map.
Returns the value of the property for the given object from this read-only map.
Populates the given destination map with entries having the keys obtained by applying the transform function to each entry in this Map and the values of this map.
Populates the given destination map with entries having the keys of this map and the values obtained by applying the transform function to each entry in this Map.
Returns the largest value among all values produced by selector function applied to each entry in the map.
Returns the largest value according to the provided comparator among all values produced by selector function applied to each entry in the map or null
if there are no entries.
Returns the first entry having the largest value according to the provided comparator or null
if there are no entries.
Returns the smallest value among all values produced by selector function applied to each entry in the map.
Returns the smallest value according to the provided comparator among all values produced by selector function applied to each entry in the map or null
if there are no entries.
Returns a map containing all entries of the original map except the entry with the given key.
Returns a map containing all entries of the original map except those entries the keys of which are contained in the given keys array.
Returns a map containing all entries of the original map except those entries the keys of which are contained in the given keys collection.
Returns a map containing all entries of the original map except those entries the keys of which are contained in the given keys sequence.
Returns the first entry having the smallest value according to the provided comparator or null
if there are no entries.
Creates a new read-only map by replacing or adding entries to this map from a given array of key-value pairs.
Creates a new read-only map by replacing or adding an entry to this map from a given key-value pair.
Creates a new read-only map by replacing or adding entries to this map from a given collection of key-value pairs.
Creates a new read-only map by replacing or adding entries to this map from another map.
Creates a new read-only map by replacing or adding entries to this map from a given sequence of key-value pairs.
Returns a new read-only map containing all key-value pairs from the original map.
Populates and returns the destination mutable map with key-value pairs from the given map.
Returns a new mutable map containing all key-value pairs from the original map.
Converts this Map to a Properties object.
Converts this Map to a SortedMap. The resulting SortedMap determines the equality and order of keys according to their natural sorting order.
Converts this Map to a SortedMap. The resulting SortedMap determines the equality and order of keys according to the sorting order provided by the given comparator.
