Class CommandLineArgsFactory

java.lang.Object

com.facebook.buck.core.rules.actions.lib.args.CommandLineArgsFactory

public class CommandLineArgsFactory
extends Object

Factory class that returns more efficient implementations of CommandLineArgs depending on what type of arguments are available (e.g. a list of args may return a different concrete class than a single arg)

This should be the public way to construct CommandLineArgs objects.
