Class MojoFrame

java.lang.Object

ai.h2o.mojos.runtime.frame.MojoFrame

public class MojoFrame
extends java.lang.Object

Container for MojoColumns as well as some additional meta data. MojoFrames are mostly immutable; it’s column/row count, column references, and associated names for said references cannot be modified once created. The data of a individual column can be modified, however, through the getColumnData method.

MojoFrames can only be constructed through a MojoFrameBuilder (see MojoFrameBuilder for more details).
