override
addEntries(Iterable<MapEntry<K, V>> newEntries) → void
Adds all key/value pairs of newEntries to this map.

Available on JsonRow, provided by the SqlRowExtensions extension

Generates a WHERE clause for the given map of column names and values.
cast<RK, RV>() → Map<RK, RV>
Provides a view of this map as having RK keys and RV instances, if necessary.
override
clear() → void
Removes all entries from the map.
override

Whether this map contains the given key.
override
containsValue(Object? value) → bool
Whether this map contains the given value.
override
forEach(void action(K key, V value)) → void
Applies action to each key/value pair of the map.
override
generateSqlCall(String procedureName, String dataBaseProvider, [bool nullAsBlank = false, dynamic quoteChar]) → String

Available on JsonRow, provided by the SqlRowExtensions extension

Generates a SQL call string for a given stored procedure and database provider.
map<K2, V2>(MapEntry<K2, V2> transform(K key, V value)) → Map<K2, V2>
Returns a new map where all entries of this map are transformed by the given convert function.
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
putIfAbsent(K key, V ifAbsent()) → V
Look up the value of key, or add a new entry if it isn't there.
override
remove(Object? key) → V?
Removes key and its associated value, if present, from the map.
override
removeWhere(bool test(K key, V value)) → void
Removes all entries of this map that satisfy the given test.
override
toJson() → Map<String, dynamic>
Returns a JSON representation of the map.
toJsonString() → string
