Class LongFactory3D

  • All Implemented Interfaces:
    Serializable, Cloneable


    public class LongFactory3Dextends PersistentObject
    Factory for convenient construction of 3-d matrices holding int cells. Use idioms like LongFactory3D.dense.make(4,4,4) to construct dense matrices, LongFactory3D.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:
      LongFactory3D F = LongFactory3D.dense;  F.make(4,4,4);  F.descending(10,20,5);  F.random(4,4,5);  ...

      • ascending

        public LongMatrix3D ascending(int slices,                     int rows,                     int columns)
        Constructs a matrix with cells having ascending values. For debugging purposes.
      • descending

        public LongMatrix3D descending(int slices,                      int rows,                      int columns)
        Constructs a matrix with cells having descending values. For debugging purposes.
      • make

        public LongMatrix3D make(long[][][] 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 uniformly distributed values in (0,1) (exclusive).
