Constructor Detail

SequenceIterator

public SequenceIterator(int length)

Creates a new SequenceIterator with maximal length.

Parameters:

length - the maximal length

Method Detail

next

public boolean next()

Changes the internal sequence representation to the next sequence.

Returns:

true if the new sequence is correct, otherwise false

reset

public void reset()

Resets the internal sequence representation. So the sequence iterator starts again.

setBounds

public void setBounds(int[] bounds)

This method sets the bounds for each position. It does not copy the array and it doesnot proof bounds.length <= length. This has to be ensured by the user

Parameters:

bounds -

skip

public boolean skip(int firstPos)

This method skips some position.

Parameters:

firstPos - the first position that is interesting.

Returns:

true if the internal sequence is from the scope.
