Class StandaloneReadableTuple

java.lang.Object

com.linkedin.feathr.common.tensor.StandaloneReadableTuple

All Implemented Interfaces:

ReadableTuple

public class StandaloneReadableTuple
extends java.lang.Object
implements ReadableTuple

A readable tuple implementation that stores single tensor row data independent of a tensor aka in standalone manner. This implements equality and hashcode methods so it can be used as a key in maps

Constructor Detail

StandaloneReadableTuple

public StandaloneReadableTuple(StandaloneReadableTuple standaloneReadableTuple)

Copies StandaloneReadableTuple. It shares all the underlying data.

Parameters:

standaloneReadableTuple - StandaloneReadableTuple to make copy of

StandaloneReadableTuple

public StandaloneReadableTuple(ReadableTuple readableTuple)

StandaloneReadableTuple

public StandaloneReadableTuple(ReadableTuple readableTuple,
                               boolean dimOnly)

Creates a StandaloneReadableTuple from a ReadableTuple optionally by dropping last value (float/double) columns. Note: this copies all the values from readableTuple so doesn't depend on underlying tensor, if any.

Parameters:

readableTuple - ReadableTuple to convert into StandaloneReadableTuple

dimOnly - value column(s) won't be copied if true, all columns will be copied otherwise.
