| GradientFormatter | | public GradientFormatter(float maxScore, String minForegroundColor, String maxForegroundColor, String minBackgroundColor, String maxBackgroundColor)(Code) | | Sets the color range for the IDF scores
Parameters:
maxScore - The score (and above) displayed as maxColor (SeeQueryScorer.getMaxWeight which can be used to callibrate scoringscale)
Parameters:
minForegroundColor - The hex color used for representing IDF scores of zero eg #FFFFFF(white) or null if no foreground color required
Parameters:
maxForegroundColor - The largest hex color used for representing IDF scores eg #000000(black) or null if no foreground color required
Parameters:
minBackgroundColor - The hex color used for representing IDF scores of zero eg #FFFFFF(white) or null if no background color required
Parameters:
maxBackgroundColor - The largest hex color used for representing IDF scores eg #000000(black) or null if no background color required |

| hexToInt | | final public static int hexToInt(String hex)(Code) | | Converts a hex string into an int. Integer.parseInt(hex, 16) assumes the
input is nonnegative unless there is a preceding minus sign. This method
reads the input as twos complement instead, so if the input is 8 bytes
long, it will correctly restore a negative int produced by
Integer.toHexString() but not neccesarily one produced by
Integer.toString(x,16) since that method will produce a string like '-FF'
for negative integer values.
Parameters:
hex - A string in capital or lower case hex, of no more then 16characters.
throws:
NumberFormatException - if the string is more than 16 characters long, or if anycharacter is not in the set [0-9a-fA-f] |
