Method Detail

isVarLength

public boolean isVarLength()

Description copied from interface: SwitchOrArgument

Does this argument or switch have a variable length? This is only allowed for the last argument/switch in the command line.

Returns:

true: this argument or switch consumes the remaining items in the command line
false: this argument or switch just consumes 1 item (for arguments) or 2 items (for switches) from the command line

getMinimalCount

public int getMinimalCount()

Description copied from interface: Argument

Get the minimum number of times this argument might appear on the command line. The default implementation returns 1.

Returns:

minimum number of appearances of this argument

getMaximalCount

public int getMaximalCount()

Description copied from interface: Argument

Get the maximum number of times this argument might appear on the command line. The default implementation returns the value of Argument.getMinimalCount()

Returns:

maximum number of appearances of this argument, use Integer.MAX_VALUE for infinity
