Method Details

start

NumericSequenceSpec<T> start(T start)

Description copied from interface: NumericSequenceGeneratorSpec

Specifies the starting value of the sequence. The default is 1.

Specified by:

start in interface NumericSequenceGeneratorSpec<T extends Number & Comparable<T>>

Parameters:

start - the initial value of the sequence

Returns:

spec builder

next

NumericSequenceSpec<T> next(UnaryOperator<T> next)

Description copied from interface: NumericSequenceGeneratorSpec

Specifies the function for calculating the next sequence value. If unspecified, the default is to increment the sequence by 1.

Specified by:

next in interface NumericSequenceGeneratorSpec<T extends Number & Comparable<T>>

Parameters:

next - a function for calculating the next value

Returns:

spec builder

nullable

NumericSequenceSpec<T> nullable()

Description copied from interface: ValueSpec

Specifies that a null value can be generated

Specified by:

nullable in interface NullableGeneratorSpec<T extends Number & Comparable<T>>

Specified by:

nullable in interface NumericSequenceGeneratorSpec<T extends Number & Comparable<T>>

Specified by:

nullable in interface ValueSpec<T extends Number & Comparable<T>>

Returns:
