Constructor Details

Mapping

public Mapping(ISemIm semIm,
 Parameter parameter,
 Matrix matrix,
 int i,
 int j)

Constructs matrix new mapping using the given freeParameters.

Parameters:

parameter - The parameter that this maps.

matrix - The array containing matrix[i][j], the element to be manipulated.

i - Left coordinates of matrix[i][j].

j - Right coordinate of matrix[i][j].

Method Details

serializableInstance

public static Mapping serializableInstance()

Generates a simple exemplar of this class to test serialization.

getValue

public double getValue()

Returns:

the value of the array element at (i, j).

setValue

public void setValue(double x)

Sets the value of the array element at the stored coordinates (i, j). If the array is symmetric sets two elements.

getParameter

public Parameter getParameter()

Returns:

the paramter that this mapping maps.

toString

public String toString()

Overrides:

toString in class Object

Returns:

a String containing information (array name and values of subscripts) about the array element associated with this mapping.
