## cern.colt.matrix
Class ObjectFactory3D

    java.lang.Object
      cern.colt.PersistentObject
          cern.colt.matrix.ObjectFactory3D

All Implemented Interfaces:
  Cloneable, Serializable

public class ObjectFactory3D
extends PersistentObject

Factory for convenient construction of 3-d matrices holding `Object` cells. Use idioms like `ObjectFactory3D.dense.make(4,4,4)` to construct dense matrices, `ObjectFactory3D.sparse.make(4,4,4)` to construct sparse matrices. If the factory is used frequently it might be useful to streamline the notation. For example by aliasing:

    ObjectFactory3D F = ObjectFactory3D.dense;
    F.make(4,4,4);
    ...

Field Detail

### dense

    public static final ObjectFactory3D dense

  A factory producing dense matrices.

### sparse

    public static final ObjectFactory3D sparse

  A factory producing sparse matrices.

Method Detail

### make

    public ObjectMatrix3D make(Object[][][] values)

  Constructs a matrix with the given cell values. `values` is required to have the form `values[slice][row][column]` and have exactly the same number of slices, rows and columns as the receiver.

  The values are copied. So subsequent changes in `values` are not reflected in the matrix, and vice-versa.

  Parameters:
    `values` - the values to be filled into the cells.
  Returns:
    `this` (for convenience only).
  Throws:
    `IllegalArgumentException` - if `values.length != slices() || for any 0 <= slice < slices(): values[slice].length != rows()`.
    `IllegalArgumentException` - if `for any 0 <= column < columns(): values[slice][row].length != columns()`.

### make

    public ObjectMatrix3D make(int slices,
                               int rows,
                               int columns)

  Constructs a matrix with the given shape, each cell initialized with zero.

### make

    public ObjectMatrix3D make(int slices,
                               int rows,
                               int columns,
                               Object initialValue)

  Constructs a matrix with the given shape, each cell initialized with the given value.
