Method Detail

getName

public java.lang.String getName()

getParam

public java.lang.String getParam()

stringToColor

public static java.awt.Color stringToColor(java.lang.String name)

Returns the color constant with the given name. The match is not case sensitive, so "LightGray", "LIGHTGRAY", and "light_gray" all return the color constant referred to as Color.LightGray or Color.LIGHT_GRAY. If no matching color constant could be found, this method returns null.

splitPairs

public static StringValueMap splitPairs(java.lang.String s)

Splits the given string into name=value pairs. The returned map associates key strings with string, Integer or int[] values. The input string is expected to be a white-space-delimited list of name=value pairs with no space within the name. If the value contains space, then it is expected to be enclosed in double quotes. if the value can be interpreted as an int, it will be stored in the map as an Integer object. If the value is enclosed in square brackets, and consists entirely of comma and white-space-delimited integer values, it is stored as an int array. Otherwise, it is returned as a string. Any tokens that are found that do not contain an equals sign are returned as a concatenated, space-delimited string using the empty string as the key. All names are converted to lower case.

toString

public java.lang.String toString()
