All Implemented Interfaces:

Serializable, Cloneable

public class DenseLargeIntMatrix3D
extends WrapperIntMatrix3D

Dense 3-d matrix holding int elements. First see the package summary and javadoc tree view to get the broad picture.

Implementation:

This data structure allows to store more than 2^31 elements. Internally holds one three-dimensional array, elements[slices][rows][columns]. Note that this implementation is not synchronized.

Time complexity:

O(1) (i.e. constant time) for the basic operations get, getQuick, set, setQuick and size.

Constructor Detail

DenseLargeIntMatrix3D

public DenseLargeIntMatrix3D(int slices,
                             int rows,
                             int columns)

Method Detail

getQuick

public int getQuick(int slice,
                    int row,
                    int column)

Description copied from class: IntMatrix3D

Returns the matrix cell value at coordinate [slice,row,column].

Provided with invalid parameters this method may return invalid objects without throwing any exception. You should only use this method when you are absolutely sure that the coordinate is within bounds. Precondition (unchecked): slice<0 || slice>=slices() || row<0 || row>=rows() || column<0 || column>=column().

Overrides:

getQuick in class WrapperIntMatrix3D

Parameters:

slice - the index of the slice-coordinate.

row - the index of the row-coordinate.

column - the index of the column-coordinate.

Returns:

the value at the specified coordinate.

setQuick

public void setQuick(int slice,
                     int row,
                     int column,
                     int value)

Description copied from class: IntMatrix3D

Sets the matrix cell at coordinate [slice,row,column] to the specified value.

Provided with invalid parameters this method may access illegal indexes without throwing any exception. You should only use this method when you are absolutely sure that the coordinate is within bounds. Precondition (unchecked): slice<0 || slice>=slices() || row<0 || row>=rows() || column<0 || column>=column().

Overrides:

setQuick in class WrapperIntMatrix3D

Parameters:

slice - the index of the slice-coordinate.

row - the index of the row-coordinate.

column - the index of the column-coordinate.

value - the value to be filled into the specified cell.

elements

public int[][][] elements()

Description copied from class: IntMatrix3D

Returns the elements of this matrix.

Overrides:

elements in class WrapperIntMatrix3D

Returns:

the elements

like

public IntMatrix3D like(int slices,
                        int rows,
                        int columns)

Description copied from class: IntMatrix3D

Construct and returns a new empty matrix of the same dynamic type as the receiver, having the specified number of slices, rows and columns. For example, if the receiver is an instance of type DenseIntMatrix3D the new matrix must also be of type DenseIntMatrix3D, if the receiver is an instance of type SparseIntMatrix3D the new matrix must also be of type SparseIntMatrix3D, etc. In general, the new matrix should have internal parametrization as similar as possible.

Overrides:

like in class WrapperIntMatrix3D

Parameters:

slices - the number of slices the matrix shall have.

rows - the number of rows the matrix shall have.

columns - the number of columns the matrix shall have.

Returns:

a new empty matrix of the same dynamic type.
