Package cern.colt.matrix
Class ObjectFactory3D
java.lang.Object
cern.colt.PersistentObject
cern.colt.matrix.ObjectFactory3D
- All Implemented Interfaces:
Serializable
,Cloneable
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); ... |

Method Details

make
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().
