BASE_IDENTIFIER

public static final String BASE_IDENTIFIER

Identifier of the unspecified precision numeric type. It corresponds to Java SDK's Schema.FieldType.DECIMAL. It is the underlying representation type of FixedPrecisionNumeric logical type in order to be compatible with existing Java field types.

Method Details

of

public static FixedPrecisionNumeric of(int precision,
 int scale)

Create a FixedPrecisionNumeric instance with specified precision and scale. ``precision=-1`` indicates unspecified precision.

of

public static FixedPrecisionNumeric of(int scale)

Create a FixedPrecisionNumeric instance with specified scale and unspecified precision.

of

public static FixedPrecisionNumeric of(Row row)

Create a FixedPrecisionNumeric instance with specified argument row.
