Interface ISequence

All Known Implementing Classes:

AbstractSequence, ListSizeSequence, Sequence, SimpleSequence

public interface ISequence

Interface for sequence specifications. A sequence in the interval of integer numbers: [getStart(), getStart()+getStep(), getStart()+2*getStep(), ..., getEnd()]

Method Summary

Modifier and Type	Method and Description
int	getEnd() Get the end index for this sequence
int[]	getIndices() Get the generated sequence of indices for this ISequence.
int	getStart() Get the start index for this sequence
int	getStep() The step for calculating the next index in the sequence.
void	setListSize(int size) Sets the list size of the current used list in the generics library.

Method Detail

getEnd

int getEnd()

Get the end index for this sequence

Returns:

the endOffset of this sequence + 1;

getIndices

int[] getIndices()

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

Returns:

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

getStart

int getStart()

Get the start index for this sequence

Returns:

the start offset of this sequence;

getStep

int getStep()

The step for calculating the next index in the sequence.

Returns:

the step size of this sequence;

setListSize

void setListSize(int size)

Sets the list size of the current used list in the generics library. Sometimes this setting is used by special sequence implementations.

Parameters:

size -
