Detailed Description

Proxy aggregator. Mirrors and forwards calls to the corresponding Java aggregator. The constructor creates a new reference to the Java object (so that it doesn't get garbage collected.) The destructor will delete the reference to allow the corresponding Java object to be garbaged collected. The copy constructor clones the Java object.

Constructor & Destructor Documentation

proxy_aggregator::proxy_aggregator	(	JNIEnv *	env,
		jobject &	java_aggregator
	)

Constructor for proxy aggregator. Initializes this object with the associated Java org.graphlab.Updater object.

Parameters:

[in]	env	JNI environment - used to create a new reference to javaUpdater.
[in]	java_aggregator	Java org.graphlab.Aggregator object. This constructor will create a new reference to the object to prevent garbage collection.

Definition at line 63 of file org_graphlab_Aggregator.cpp.

proxy_aggregator::proxy_aggregator

(

)

The default constructor does nothing

Definition at line 66 of file org_graphlab_Aggregator.cpp.

proxy_aggregator::proxy_aggregator

(

const proxy_aggregator &

other

)

Copy constructor for proxy_aggregator. If other has a mobj, creates a new reference to it.

Definition at line 70 of file org_graphlab_Aggregator.cpp.

proxy_aggregator::~proxy_aggregator

(

)

Deletes the reference to the Java object so that it may be garbage collected.

Definition at line 92 of file org_graphlab_Aggregator.cpp.

Definition at line 46 of file java_any.cpp.

proxy_aggregator & proxy_aggregator::operator=

(

const proxy_aggregator &

other

)

Copy assignment operator for proxy_aggregator. If other has a mobj, creates a new reference to it.

Definition at line 84 of file org_graphlab_Aggregator.cpp.

void java_any::set_obj ( jobject  obj )

protectedinherited

Deletes the current ref (if any) and creates a new ref if obj is not null.

Parameters:

[in]

obj

replaces current object ref
