All Implemented Interfaces:

Representable, Serializable

public final class PrimitiveDimensionType
extends DimensionType

The most basic type of a dimension. Only specifies the primitive type and an optional shape ("size"), without any high-level metadata.

Method Details

withShape

public PrimitiveDimensionType withShape(int shape)

Parameters:

shape - the shape of the new type.

Returns:

a copy of this type with a new shape.

getShape

public int getShape()

Description copied from class: DimensionType

Get the shape.

Overrides:

getShape in class DimensionType

Returns:

the shape - the number of maximum possible unique values in this dimension. Can be UNKNOWN_SHAPE.

getRepresentation

public Primitive getRepresentation()

getName

public String getName()

Description copied from class: DimensionType

Get the name of the DimensionType

Overrides:

getName in class DimensionType

Returns:

the name

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

setDimensionValue

public void setDimensionValue(WriteableTuple target,
 int column,
 Object dimensionValue)

Description copied from class: DimensionType

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.

Overrides:

setDimensionValue in class DimensionType

Parameters:

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

toString

public String toString()

Overrides:

toString in class Object
