Uses of Class org.apache.mahout.h2obindings.H2OContext (Mahout H2O backend 0.10.1 API)

java.lang.Object
+
- org.apache.mahout.h2obindings.drm.H2OBCast<T>
+

+
+
All Implemented Interfaces:
+
Serializable, org.apache.mahout.math.drm.BCast<T>
+
+
+
+
```
public class H2OBCast<T>
+extends Object
+implements org.apache.mahout.math.drm.BCast<T>, Serializable
```
+
Broadcast class wrapper around Matrix and Vector. + + Use MatrixWritable and VectorWritable internally. + Even though the class is generically typed, we do runtime + enforcement to assert the type is either Matrix or Vector. + + H2OBCast object is created around a Matrix or Vector. Matrix or Vector + objects cannot be freely referred in closures. Instead create and refer the + corresponding H2OBCast object. The original Matrix or Vector can be + obtained by calling the ->value() method on the H2OBCast object within a + closure.
