Class StandaloneReadableTuple

java.lang.Object
com.linkedin.feathr.common.tensor.StandaloneReadableTuple
All Implemented Interfaces:
ReadableTuple
public class StandaloneReadableTuple extends 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 Details

    • 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.
