Examples of org.jruby.embed.internal.BiVariableMap

org.jruby.embed.internal.BiVariableMap
Ruby-Java bi-directional variable map implementation. Keys of this map should be String, and values should be {@link 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 {@link ScriptingContainer} is shared by multiple threads, specify thread safefor 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));
```
