Method Detail

self

protected abstract THIS self()

Specified by:

self in class Types.Builder<THIS extends Types.BasePrimitiveBuilder<P,THIS>,P>

length

public THIS length(int length)

Adds the length for a FIXED_LEN_BYTE_ARRAY.

Parameters:

length - an int length

Returns:

this builder for method chaining

precision

@Deprecated
public THIS precision(int precision)

Deprecated.

use Types.Builder.as(LogicalTypeAnnotation) with the corresponding decimal type instead

Adds the precision for a DECIMAL.

This value is required for decimals and must be less than or equal to the maximum number of base-10 digits in the underlying type. A 4-byte fixed, for example, can store up to 9 base-10 digits.

Parameters:

precision - an int precision value for the DECIMAL

Returns:

this builder for method chaining

scale

@Deprecated
public THIS scale(int scale)

Deprecated.

use Types.Builder.as(LogicalTypeAnnotation) with the corresponding decimal type instead

Adds the scale for a DECIMAL.

This value must be less than the maximum precision of the type and must be a positive number. If not set, the default scale is 0.

The scale specifies the number of digits of the underlying unscaled that are to the right of the decimal point. The decimal interpretation of values in this column is: value*10^(-scale).

Parameters:

scale - an int scale value for the DECIMAL

Returns:

this builder for method chaining

columnOrder

public THIS columnOrder(ColumnOrder columnOrder)

Adds the column order for the primitive type.

In case of not set the default column order is ColumnOrder.ColumnOrderName.TYPE_DEFINED_ORDER except the type PrimitiveType.PrimitiveTypeName.INT96 and the types annotated by OriginalType.INTERVAL where the default column order is ColumnOrder.ColumnOrderName.UNDEFINED.

Parameters:

columnOrder - the column order for the primitive type

Returns:

this builder for method chaining

build

protected PrimitiveType build(String name)

Specified by:

build in class Types.Builder<THIS extends Types.BasePrimitiveBuilder<P,THIS>,P>

decimalMetadata

protected DecimalMetadata decimalMetadata()
