run

public void run(ArgumentParser parser,
 Argument arg,
 Map<String,Object> attrs,
 String flag,
 Object value)

Description copied from interface: ArgumentAction

Executes this action.

If the objects derived from RuntimeException are thrown in this method because of invalid input from command line, subclass must catch these exceptions and wrap them in ArgumentParserException and give simple error message to explain what happened briefly.

Specified by:

run in interface ArgumentAction

Parameters:

parser - The parser.

arg - The argument this action attached to.

attrs - Map to store attributes.

flag - The actual option flag in command line if arg is a named arguments. null if arg is a positional argument.

value - The attribute value. This may be null if this action does not consume any arguments.

 Argument arg,
 Map<String,Object> attrs,
 String flag,
 Object value,
 Consumer<Object> valueSetter)

Description copied from interface: ArgumentAction

Executes this action.

If the objects derived from RuntimeException are thrown in this method because of invalid input from command line, subclass must catch these exceptions and wrap them in ArgumentParserException and give simple error message to explain what happened briefly.

Specified by:

run in interface ArgumentAction

Parameters:

parser - The parser.

arg - The argument this action attached to.

attrs - The current map of attributes. Implementations may read from this map, but may not change it. Implementations must call the valueSetter with the actual value to be set.

flag - The actual option flag in command line if arg is a named arguments. null if arg is a positional argument.

value - The attribute value. This may be null if this action does not consume any arguments.

valueSetter - The consumer that will set the actual value determined by this action in the result.
