def
getDimensionValue(tuple: ReadableTuple, column: Int): AnyRef
The inverse of
#setDimensionValue.The inverse of
#setDimensionValue. Reads a dimension from a particular column of a tuple.- tuple
the tuple from which to read. Hint: This will often be a
com.linkedin.feathr.common.tensor.TensorIterator- column
the column to read from the tuple
- returns
the value of the dimension

def
getName(): String
Get the name of the DimensionType
Get the name of the DimensionType
- returns
the name
-
def
getShape(): Int
Get the shape.
Get the shape.
- returns
the shape - the number of maximum possible unique values in this dimension. Can be UNKNOWN_SHAPE.

def
setDimensionValue(target: WriteableTuple, column: Int, dimensionValue: Any): Unit
Sets a dimension in a particular column of a target tuple.
Sets a dimension in a particular column of a target tuple. For primitive dimensions, implementations will just copy the value over. (This is the default behavior.) For high-level semantic dimensions that maintain a different set of "outward-facing" and "internal" representations of the dimension values, implementations will apply any necessary translation on the input dimensionValue before inserting into the tuple.
- target
the destination where the dimension value should be set. Hint: This will often be a
com.linkedin.feathr.common.TensorBuilder- column
the column number of the target tuple to be set
- dimensionValue
the value of the dimension
- Exceptions thrown
RuntimeExceptionwill be thrown if value is not valid for this dimension
