jobjRef-class.Rd
This class describes a reference to an object held in a JavaVM.
Objects of this class should *not* be created directly. Instead, the function .jnew
should be use to create new Java objects. They can also be created as results of the .jcall
function.
jobj
:Internal identifier of the object (external pointer to be precise)
jclass
:Java class name of the object (in JNI notation)
Java-side attributes are not accessed via slots, but the $
operator instead.
This object's Java methods are not accessed directly. Instead, .jcall
JNI-API should be used for invoking Java methods. For convenience the $
operator can be used to call methods via reflection API.
