Class ComplexData

java.lang.Object
  com.multicorebsp.util.MatrixData<ComplexData>
      com.multicorebsp.util.ComplexData

All Implemented Interfaces:

com.multicorebsp.core.CompulsaryCloneable<ComplexData>, java.lang.Cloneable

public class ComplexData
extends MatrixData<ComplexData>

Enables storage of complex data in matrices.

Field Summary

double[]	imag Stores the complex values in double precision.
double[]	real Stores the real values in double precision.

Constructor Summary

	ComplexData() Base constructor, all data arrays remain null.
protected	ComplexData(ComplexData toCopy) Deep copy constructor.
	ComplexData(double[] _R, double[] _I) Base constructor, copies data handle by reference(!).
	ComplexData(int length) Base constructor, initialises zero data.

Method Summary

void	add(int i, int j) Adds the values of two nonzeroes and saves it at the last index available.
void	parseAndWrite(int i, java.util.Scanner s) Parses an input stream and writes the contect to the i'th index.
void	removeDuplicates(int nr) Removes duplicates from the data structure.
ComplexData	safeClone()
ComplexData	safeClone(int i, int j) Clones only a subset of the data.
void	swap(int i, int j) Swaps data elements.

Method Detail

add

public void add(int i,
                int j)

Description copied from class: MatrixData

Adds the values of two nonzeroes and saves it at the last index available.

Specified by:

add in class MatrixData<ComplexData>

Parameters:

i - First nonzero index (will remain unchanged).

j - Second nonzero index (will be replaced by sum).

removeDuplicates

public void removeDuplicates(int nr)

Description copied from class: MatrixData

Removes duplicates from the data structure. Assumed is all duplicates reside at the last part of the data structure.

Specified by:

removeDuplicates in class MatrixData<ComplexData>

Parameters:

nr - Number of elements to remove.

swap

public void swap(int i,
                 int j)

Description copied from class: MatrixData

Swaps data elements.

Specified by:

swap in class MatrixData<ComplexData>

Parameters:

i - First index

j - Second index

safeClone

public ComplexData safeClone()

safeClone

public ComplexData safeClone(int i,
                             int j)

Description copied from class: MatrixData

Clones only a subset of the data.

Specified by:

safeClone in class MatrixData<ComplexData>

Parameters:

i - Lower bound of the index to copy.

j - Upper bound on the index to copy.

Returns:

Partial clone of the current object.

parseAndWrite

public void parseAndWrite(int i,
                          java.util.Scanner s)

Description copied from class: MatrixData

Parses an input stream and writes the contect to the i'th index.

Specified by:

parseAndWrite in class MatrixData<ComplexData>

Parameters:

i - At what index to save input.

s - Where to get the input from.
