public class BiVariableMap<K,V> extends Object implements Map<K,V>
BiVariable type object.
This map does not permit null or empty key. Each operation of this class is not
synchronized; however, concurrent access to values are synchronized. When
ScriptingContainer is shared by multiple threads, specify thread safe
for a local context scope, which makes a map thread local.
Usage example:
ScriptingContainer container = new ScriptingContainer();
Map map = container.getVarMap();
map.put("@coefficient", new Float(3.14));
or, using a shortcut method:
*
ScriptingContainer container = new ScriptingContainer();
container.put("@coefficient", new Float(3.14));| Constructor and Description |
