Invoke methods on Java object references. These functions provide a mechanism for invoking various Java object methods directly from R.
invoke(jobj, method, ...)invoke_static(sc, class, method, ...)
invoke_new(sc, class, ...)
An R object acting as a Java object reference (typically, a spark_jobj).
The name of the method to be invoked.
Optional arguments, currently unused.
A spark_connection.
The name of the Java class whose methods should be invoked.
Use each of these functions in the following scenarios:
invoke | Execute a method on a Java object reference (typically, a spark_jobj). | invoke_static |
| Execute a static method associated with a Java class. | invoke_new | Invoke a constructor associated with a Java class. |
