Method Detail

toMap
public java.util.Map<java.lang.String,java.lang.String> toMap()
Description copied from interface:ReadOnlyStringMap
Returns a non-null
mutableMap<String, String>
containing a snapshot of this data structure.- Specified by:
toMap
in interfaceReadOnlyStringMap
- Returns:
- a mutable copy of this data structure in
Map<String, String>
form.
-
containsKey
public boolean containsKey(java.lang.String key)
Description copied from interface:ReadOnlyStringMap
Returnstrue
if this data structure contains the specified key,false
otherwise.- Specified by:
containsKey
in interfaceReadOnlyStringMap
- Parameters:
key
- the key whose presence to check. May benull
.- Returns:
true
if this data structure contains the specified key,false
otherwise.
-
forEach
public <V> void forEach(BiConsumer<java.lang.String,? super V> action)
Description copied from interface:ReadOnlyStringMap
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.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
'sBiConsumer.accept(Object, Object)
accept} method may cause aConcurrentModificationException
to be thrown.- Specified by:
forEach
in interfaceReadOnlyStringMap
- Type Parameters:
V
- type of the value.- Parameters:
action
- The action to be performed for each key-value pair in this collection.
-
forEach
public <V,S> void forEach(TriConsumer<java.lang.String,? super V,S> action, S state)
Description copied from interface:ReadOnlyStringMap
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.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.
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
TriConsumer
'saccept
method may cause aConcurrentModificationException
to be thrown.- Specified by:
forEach
in interfaceReadOnlyStringMap
- Type Parameters:
V
- type of the value.S
- type of the third parameter.- Parameters:
action
- The action to be performed for each key-value pair in this collection.state
- the object to be passed as the third parameter to each invocation on the specified triconsumer.
-
getValue
public <V> V getValue(java.lang.String key)
Description copied from interface:ReadOnlyStringMap
Returns the value for the specified key, ornull
if the specified key does not exist in this collection.- Specified by:
getValue
in interfaceReadOnlyStringMap
- Parameters:
key
- the key whose value to return.- Returns:
- the value for the specified key or
null
.
