Method Detail

setLine

public static void setLine(BitSet[] data,
                           int lineNr,
                           int setTo)

Sets a line in an array of SampleDatas to represent an integer using little endian. SampleDatas stacked vertically so a line is the set of all items of same index in each them.

Parameters:

data - where to encode this integer

lineNr - at what line to encode it

setTo - the integer to encode

getLine

public static int getLine(BitSet[] data,
                          int lineNr,
                          int start,
                          int end)

A kind of reverse of setLine will decode a binary integer from a line in an array of SampleDatas. Little endian is used.

Parameters:

data - where to decode the integer from.

lineNr - what line to decode it from.

start - what SampleData to start reading from.

end - up to what SampleData to read inclusive.

getLine

public static int getLine(BitSet[] data,
                          int lineNr)

Same as getLine( data, lineNr, 0, data.length - 1 )

getChunks

public static BitSet[] getChunks(BitSet[] data,
                                 int startY,
                                 int secLenY,
                                 int firstX,
                                 int lastX)

Extracts sections out SampleDatas in an array.

Parameters:

data - The SampleDatas we're getting stuff from.

startY - Index within SampleDatas at which to start extracting.

secLen - Length of section within SampleDatas we want to extract.

firstX - Index of first SampleData to include in output.

lastX - Index of last SampleData to include in output inclusive.

Returns:

Sections of the SampleDatas in data in an array.

getChunks

public static BitSet[] getChunks(BitSet[] data,
                                 int start,
                                 int secLen)

Same as getChunks( data, start, secLen, 0, data.length - 1 )

binomialCoefficient

public static int binomialCoefficient(int n,
                                      int r)

fact

public static int fact(int n)

sampleDatasToString

public static java.lang.String sampleDatasToString(SampleData[] as,
                                                   SampleData[] bs)

Will print these SampleDatas side by side. Array elements in X axis, SampleData bits in Y axis. Takes into account difference in SampleSeparation but ASSUMES bs HAS SAMPLESEPARATION = 1.

getLines

public static SampleData[] getLines(SampleData[] src,
                                    int firstInc,
                                    int howMany)

stretch

public static BitSet stretch(BitSet what,
                             int factor)

indexOf

public static int indexOf(java.lang.Object pin,
                          java.lang.Object[] hay)

indexOf

public static int indexOf(int pin,
                          int[] hay)

int2BinStr

public static java.lang.String int2BinStr(int num,
                                          int width)

log2
