Constructor Detail

CSD

public CSD(Holder holder)

CSD class constructor

Parameters:

holder - Holder object that will be manipulated

Method Detail

scanForOne

private int scanForOne()

Scan representation for the next one bit

Returns:

bit number if a one is found or -1 if not.

peekForOne

private boolean peekForOne()

Peek to see if there is another one in the representation

Returns:

true if there is another one bit; false otherwise

createReplacementRun

private int[] createReplacementRun(int count)

Create an array of integers destined to replace the run in the representation.

Parameters:

count - is the number of ones in the run

Returns:

an array of ints containing the run replacement.

replaceRun

private boolean replaceRun()

Scans the representation replacing any runs of ones found

Returns:

true if a replacement was made; false if not

convertToCSD

public void convertToCSD()

Convert a normal representation into a CSD representation. A conversion is performed on both the decimal and fraction portions of the representation (as long as they are not zero).
