decideTruth

public static boolean decideTruth(java.lang.String target,
                                  boolean defaultValue)

Decide truth only if target is not null and is one or more characters (any value). If it is null, the defaultValue will be returned as the truth. This is not case sensitive. Leading and trailing whitespace is ignored. The following is true: 'TRUE', 'T', 'YES', 'y', integer numbers 1 or more. The following is false: 'FALSE', 'F', 'NO', 'n', number 0 or negative, floating point numbers.
It will never throw an exception, since any problem means it is false.

Parameters:

target - The statement to examine. This will be treated like a 7-bit ascii string!

defaultValue - the default value.

Returns:

How true (in English) the statement is.
