Method Details

countColumns

public long countColumns()

Description copied from interface: Structure2D

Only need to implement if the structure may contain more than Integer.MAX_VALUE elements.

Specified by:

countColumns in interface Structure2D

Returns:

The number of columns

countRows

public long countRows()

Description copied from interface: Structure2D

Only need to implement if the structure may contain more than Integer.MAX_VALUE elements.

Specified by:

countRows in interface Structure2D

Returns:

The number of rows

elements

public ElementView1D<N,?> elements()

Description copied from interface: Access1D

Returns an Iterable of ElementView1D. It allows to iterate over the instance's element "positions" without actually extracting the elements (unless you explicitly do so).

Specified by:

elements in interface Access1D<N extends Comparable<N>>

getColDim

public int getColDim()

Specified by:

getColDim in interface Structure2D

Returns:

The number of columns

getRowDim

public int getRowDim()

Specified by:

getRowDim in interface Structure2D

Returns:

The number of rows

nonzeros

public ElementView1D<N,?> nonzeros()

Description copied from interface: Access1D

Similar to Access1D.elements() but avoids elements that are structurally known to be zero. (That does not eliminate all zero-values from this view.) With an arbitrary (dense) unstructured implementation the Access1D.nonzeros() and Access1D.elements() methods do the same thing! Only some specific implementations are able to actually exploit structure/sparsity to view fewer elements.

Specified by:

nonzeros in interface Access1D<N extends Comparable<N>>

supplyTo

public void supplyTo(PhysicalStore<N> receiver)

Specified by:

supplyTo in interface Access2D.Collectable<N extends Comparable<N>, PhysicalStore<N extends Comparable<N>>>

getCurrent

private SparseArray<N> getCurrent()
