Constructor Details

ExpVectorIterator

public ExpVectorIterator(int nv)

ExpVector iterator constructor.

Parameters:

nv - number of variables.

ExpVectorIterator

public ExpVectorIterator(int nv,
 long ub)

ExpVector iterator constructor.

Parameters:

nv - number of variables.

ub - upper bound for the components.

ExpVectorIterator

protected ExpVectorIterator(int nv,
 boolean inf,
 long ub)

ExpVector iterator constructor.

Parameters:

nv - number of variables.

inf - true, if all elements between 0 and upper bound are enumerated, false, if only elements of exact upper bund are to be processed.

ub - an upper bound for the entries.

Method Details

hasNext

public boolean hasNext()

Test for availability of a next long.

Specified by:

hasNext in interface Iterator<ExpVector>

Returns:

true if the iteration has more ExpVectors, else false.

next

public ExpVector next()

Get next ExpVector.

Specified by:

next in interface Iterator<ExpVector>

Returns:

next ExpVector.

remove

public void remove()

Remove a tuple if allowed.

Specified by:

remove in interface Iterator<ExpVector>
