totalCount

long totalCount()

Returns the total count.

lowInterval

long lowInterval(int symbol)

Returns the low interval cumulative count of a symbol

highInterval

long highInterval(int symbol)

Returns the high interval cumulative count of a symbol

countToSymbol

int countToSymbol(int cum)

Return the symbol with the cumulative count

reset

void reset()

State reset to the initial values
