Method Details

getKey
Get the key- Returns:
- the key (of the single entry in this map)
-
getValue
Get the value- Returns:
- the value (of the single entry in this map)
-
get
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
Get the set of all key values in the map. -
keyValuePairs
Get the set of all key-value pairs in the map- Specified by:
keyValuePairs
in classMapItem
- Returns:
- an iterable containing all the key-value pairs
-
addEntry
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
Remove an entry from the map -
conforms
Ask whether the map conforms to a given map type -
getItemType
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:
getItemType
in classMapItem
- Parameters:
th
- the type hierarchy cache- Returns:
- the type of this map
-
getKeyUType
Get the lowest common item type of the keys in the map- Specified by:
getKeyUType
in classMapItem
- Returns:
- the most specific type to which all the keys belong. If the map is empty, return UType.VOID
