Method Details

build

public M build()

Specified by:

build in interface Factory2D.Builder<N extends Comparable<N>>

count

public long count()

Description copied from interface: Structure2D

count() == countRows() * countColumns()

Specified by:

count in interface Structure1D

Specified by:

count in interface Structure2D

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:
