Method Detail

self

protected Types.PrimitiveBuilder<P> self()

Specified by:

self in class Types.Builder<Types.PrimitiveBuilder<P>,P>

length

public Types.PrimitiveBuilder<P> length(int length)

Adds the length for a FIXED_LEN_BYTE_ARRAY.

Parameters:

length - an int length

Returns:

this builder for method chaining

precision

public Types.PrimitiveBuilder<P> precision(int precision)

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

public Types.PrimitiveBuilder<P> scale(int scale)

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

build

protected PrimitiveType build(String name)

Specified by:

build in class Types.Builder<Types.PrimitiveBuilder<P>,P>

decimalMetadata

protected DecimalMetadata decimalMetadata()
