clear
public void clear(int initialCapacity) -
tryPut
Description copied from interface:JenaMap
Try to put a key-value pair into the map. If the key is already present, the value is updated. -
put
Description copied from interface:JenaMap
Put a key-value pair into the map. If the key is already present, the value is updated. -
get
Description copied from interface:JenaMap
Get the value associated with the provided key. -
getOrDefault
Description copied from interface:JenaMap
Get the value associated with the provided key, or a default value if the key is not present.- Specified by:
getOrDefault
in interfaceJenaMap<K,
V> - Parameters:
key
- the key to look updefaultValue
- the default value to return if the key is not present- Returns:
- the value associated with the key, or the default value if the key is not present
-
computeIfAbsent
Description copied from interface:JenaMap
Compute a value for a key if the key is not present. The value is automatically put into the map.- Specified by:
computeIfAbsent
in interfaceJenaMap<K,
V> - Parameters:
key
- the key whose value is to retrieved or computedabsentValueSupplier
- the function to compute a value for the key, if the key is not present- Returns:
- the value associated with the key, or the value computed by the function if the key is not present
-
compute
Description copied from interface:JenaMap
Compute a value for a key.- Specified by:
compute
in interfaceJenaMap<K,
V> - Parameters:
key
- the key to compute a value forvalueProcessor
- the function to compute a value for the key. The function is passed the current value associated with the key, or null if the key is not present. The function should return the new value to associate with the key, or null if the key should be removed from the map.
-
valueIterator
Description copied from interface:JenaMap
Get an iterator over the values in the map.- Specified by:
valueIterator
in interfaceJenaMap<K,
V> - Returns:
- an iterator over the values in the map
-
valueSpliterator
Description copied from interface:JenaMap
Get a spliterator over the values in the map.- Specified by:
valueSpliterator
in interfaceJenaMap<K,
V> - Returns:
- a spliterator over the values in the map
-
