## cern.colt.matrix.objectalgo
Class Formatter

    java.lang.Object
      cern.colt.PersistentObject

              cern.colt.matrix.objectalgo.Formatter

All Implemented Interfaces:
  Cloneable, Serializable

public class Formatter
extends AbstractFormatter

Flexible, well human readable matrix print formatting. Each cell is converted using `Object.toString()`. For examples see `doublealgo.Formatter` which is just the same except that it operates on doubles.

Constructor Detail

### Formatter

    public Formatter()

  Constructs and returns a matrix formatter with alignment `LEFT`.

### Formatter

    public Formatter(String alignment)

  Constructs and returns a matrix formatter.

Parameters:
  `alignment` - the given alignment used to align a column.

Method Detail

### toSourceCode

    public String toSourceCode(ObjectMatrix1D matrix)

  Returns a string `s` such that `Object[] m = s` is a legal Java statement.

  Parameters:
    `matrix` - the matrix to format.

### toSourceCode

    public String toSourceCode(ObjectMatrix2D matrix)

  Returns a string `s` such that `Object[] m = s` is a legal Java statement.

  Parameters:
    `matrix` - the matrix to format.

### toSourceCode

    public String toSourceCode(ObjectMatrix3D matrix)

  Returns a string `s` such that `Object[] m = s` is a legal Java statement.

  Parameters:
    `matrix` - the matrix to format.

### toString

    public String toString(ObjectMatrix1D matrix)

  Returns a string representation of the given matrix.

  Parameters:
    `matrix` - the matrix to convert.

### toString

    public String toString(ObjectMatrix2D matrix)

  Returns a string representation of the given matrix.

  Parameters:
    `matrix` - the matrix to convert.

### toString

    public String toString(ObjectMatrix3D matrix)

  Returns a string representation of the given matrix.

  Parameters:
    `matrix` - the matrix to convert.

### toTitleString

    public String toTitleString(ObjectMatrix2D matrix,
                                String[] rowNames,
                                String[] columnNames,

                                String title)

  Returns a string representation of the given matrix with axis as well as rows and columns labeled. Pass `null` to one or more parameters to indicate that the corresponding decoration element shall not appear in the string converted matrix.

  Parameters:
    `matrix` - The matrix to format.
    `rowNames` - The headers of all rows (to be put to the left of the matrix).
    `columnNames` - The headers of all columns (to be put to above the matrix).
    `rowAxisName` - The label of the y-axis.
    `columnAxisName` - The label of the x-axis.
    `title` - The overall title of the matrix to be formatted.
  Returns:
    the matrix converted to a string.

### toTitleString
