Method Detail

getStep

public int getStep()

The step for calculating the next index in the sequence.

Specified by:

getStep in interface ISequence

Returns:

the step size of this sequence;

getIndices

public int[] getIndices()

Get the generated sequence of indices for this ISequence. Especially useful for unit tests to check the sequence implementation.

Specified by:

getIndices in interface ISequence

Returns:

[getStart(), getStart()+getStep(), getStart()+2*getStep(), ..., getEnd()]
