boolean |
containsKey(java.lang.String key)
Returns
true if this data structure contains the specified key, false otherwise. |
<V> void |
forEach(BiConsumer<java.lang.String,? super V> action)
Performs the given action for each key-value pair in this data structure
until all entries have been processed or the action throws an exception.
|
<V,S> void |
forEach(TriConsumer<java.lang.String,? super V,S> action,
S state)
Performs the given action for each key-value pair in this data structure
until all entries have been processed or the action throws an exception.
|
<V> V |
getValue(java.lang.String key)
Returns the value for the specified key, or
null if the specified key does not exist in this collection. |
java.util.Map<java.lang.String,java.lang.String> |
toMap()
Returns a non-
null mutable Map<String, String> containing a snapshot of this data structure. |

ReadOnlyStringMap
Some implementations may not support structural modifications (adding new elements or removing elements) while
iterating over the contents. In such implementations, attempts to add or remove elements from the
BiConsumer
's BiConsumer.accept(Object, Object)
accept} method may cause a
ConcurrentModificationException
to be thrown.

- type of the value.action
- The action to be performed for each key-value pair in this collection.public <V,S> void forEach(TriConsumer<java.lang.String,? super V,S> action, S state)
ReadOnlyStringMap
The third parameter lets callers pass in a stateful object to be modified with the key-value pairs, so the TriConsumer implementation itself can be stateless and potentially reusable.
