Method Detail
-
get
public GroundedValue get(AtomicValue key)
Get an entry from the Map
-
size
public int size()
Get the size of the map
-
isEmpty
public boolean isEmpty()
Ask whether the map is empty
-
keys
public AtomicIterator keys()
Get the set of all key values in the map.
-
keyValuePairs
public java.lang.Iterable<KeyValuePair> keyValuePairs()
Get the set of all key-value pairs in the map- Specified by:
keyValuePairsin interfaceMapItem- Returns:
- an iterable containing all the key-value pairs
-
addEntry
public MapItem addEntry(AtomicValue key, GroundedValue value)
Create a new map containing the existing entries in the map plus an additional entry, without modifying the original. If there is already an entry with the specified key, this entry is replaced by the new entry.
-
remove
public MapItem remove(AtomicValue key)
Remove an entry from the map
-
conforms
public boolean conforms(AtomicType keyType, SequenceType valueType, TypeHierarchy th)
Ask whether the map conforms to a given map type
-
getItemType
public ItemType getItemType(TypeHierarchy th)
Get the type of the map. This method is used largely for diagnostics, to report the type of a map when it differs from the required type.- Specified by:
getItemTypein interfaceMapItem- Parameters:
th- the type hierarchy cache- Returns:
- the type of this map
-
getKeyUType
public UType getKeyUType()
Get the lowest common item type of the keys in the map- Specified by:
getKeyUTypein interfaceMapItem- Returns:
- the most specific type to which all the keys belong. If the map is empty, return UType.VOID
