Class ChainedArgs

java.lang.Object
de.intarsys.tools.functor.ChainedArgs
All Implemented Interfaces:
IArgs
public class ChainedArgs extends Object implements IArgs
An IArgs implementation allowing to concat two IArgs together. Lookup will be performed in "args" first. If nothing is found, lookup is done in "fallbackArgs".

      Parameters:
      args - The main IArgs to use for lookup
      fallbackArgs - The fallback IArgs for lookup
