Class StringArrayOptionHandler

java.lang.Object

org.kohsuke.args4j.spi.OptionHandler<java.lang.String>

org.kohsuke.args4j.spi.StringArrayOptionHandler

public class StringArrayOptionHandler
extends OptionHandler<java.lang.String>

An OptionHandler for greedily mapping a list of tokens into a collection of Strings, such as String[], List<String>, etc.

How it works:

Example for parameter -s, which is String[] type:

 java -jar aaa.jar -s banan hruska jablko
 java -jar aaa.jar -s banan "hruska jablko"
 java -jar aaa.jar -s "banan hruska jablko"
 java -jar aaa.jar -s banan hruska jablko -l 4 -r
 java -jar aaa.jar -t 222 -s banan hruska jablko -r
 

All of them result in a single string array that contains three tokens "banan", "hruska", and "jablko". This OptionHandler scans for parameter which begins with "-". If it found it, it will stop.
