def toColumnMetaData(descriptorValue: String): OpVectorColumnMetadata

Transform transient feature into column metadata with an explicit descriptor value specified.
Transform transient feature into column metadata with an explicit descriptor value specified. Descriptor values are used for groupings that are not one-hot encoded, eg. text lengths or x/y coords of circle transformed dates.
descriptorValue
is the metadata created for descriptor column
returns
OpVectorColumnMetadata for vector feature
def toColumnMetaData(isNull: Boolean = false): OpVectorColumnMetadata

Transform transient feature into column metadata for use vectors (for when each feature creates one column of a vector)

def toVectorMetaData(size: Int, fieldName: Option[String] = None): OpVectorMetadata

Transform transient feature into vector metadata for use vectors (for when each feature creates multiple columns of a vector) assigns indicator group to feature name since multiple columns are created from single feature - does not provide indicator values since that needs the transform information (can copy this output with known values when available)
