Class ObjectFactory3D

java.lang.Object
cern.colt.PersistentObject
cern.colt.matrix.ObjectFactory3D
All Implemented Interfaces:
Serializable, Cloneable

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);

    • 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().

      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.
