Class DelimitedOptionHandler<T>

java.lang.Object

org.kohsuke.args4j.spi.OptionHandler<T>

org.kohsuke.args4j.spi.DelimitedOptionHandler<T>

Direct Known Subclasses:

MultiFileOptionHandler, MultiPathOptionHandler

public abstract class DelimitedOptionHandler<T>
extends OptionHandler<T>

Partial OptionHandler implementation that takes a single value to the option, which is then gets split into individual tokens by looking at a fixed delimiter.

This class is marked as abstract even though it has no abstract method, to signify the fact that the class by itself cannot be used in Option.handler() due to the extra argument that it takes.
