Description copied from interface: SequenceIncrementStep

Specifies an increment value. It may be as positive as negative

Specified by:

increment in interface SequenceIncrementStep

Parameters:

increment - value which will be added to the current sequence, when the a new value will created.

Returns:

the next step

incrementBy

public final SequenceImpl incrementBy(long increment)

Description copied from interface: SequenceIncrementStep

Specifies an increment value. It may be as positive as negative

Specified by:

incrementBy in interface SequenceIncrementStep

Parameters:

increment - value which will be added to the current sequence, when the a new value will created.
