Method Detail

getDimension

public int getDimension()

iterator

public VectorIterator<LPVectorLabel> iterator()

Description copied from interface: SparseVec

Get an iterator which iterates through all non-zero entries of the vector. The iteration must stop after exactly getNumNonZeroEntries() steps. An implementation may choose to also return zero entries during the iteration. In that case, these entries must also be counted by getNumIterations(); The iteration does not have to return the values in order of increasing indices.

Specified by:

iterator in interface SparseVec<LPVectorLabel>

Returns:

an iterator for the non-zero entries.

getNumIterations

public int getNumIterations()

Description copied from interface: SparseVec

Return the number of entries of the vector through which the iterator returned by getIterator() iterates.

Specified by:

getNumIterations in interface SparseVec<LPVectorLabel>

Returns:

the number of iterations of getIterator.

toString

public String toString()

Overrides:

toString in class Object
