ArgumentAcceptingOptionSpec (geode-joptsimple 1.0.0-incubating.M2 API)

java.lang.Object
- joptsimple.ArgumentAcceptingOptionSpec<V>

Type Parameters:

V - represents the type of the arguments this option accepts

All Implemented Interfaces:

OptionDescriptor, OptionSpec<V>
```
public abstract class ArgumentAcceptingOptionSpec<V>
extends java.lang.Object
```
Specification of an option that accepts an argument.

Instances are returned from OptionSpecBuilder methods to allow the formation of parser directives as sentences in a "fluent interface" language. For example:
```
   
   OptionParser parser = new OptionParser();
   parser.accepts( "c" ).withRequiredArg().ofType( Integer.class );
   
 
```
If no methods are invoked on an instance of this class, then that instance's option will treat its argument as a String.

```
public final <T> ArgumentAcceptingOptionSpec<T> ofType(java.lang.Class<T> argumentType)
```
    Specifies a type to which arguments of this spec's option are to be converted.
    
    JOpt Simple accepts types that have either:
    1. a public static method called valueOf which accepts a single argument of type String and whose return type is the same as the class on which the method is declared. The java.lang primitive wrapper classes have such methods.
    2. a public constructor which accepts a single argument of type String.
    This class converts arguments using those methods in that order; that is, valueOf would be invoked before a one-String-arg constructor would.
    
    Invoking this method will trump any previous calls to this method or to withValuesConvertedBy(ValueConverter).
    Type Parameters:
    
    T - represents the runtime class of the desired option argument type
    
    Parameters:
    
    argumentType - desired type of arguments to this spec's option
    
    Returns:
    
    self, so that the caller can add clauses to the fluent interface sentence
    
    Throws:
    
    java.lang.NullPointerException - if the type is null
    
    java.lang.IllegalArgumentException - if the type does not have the standard conversion methods
  - withValuesConvertedBy
```
public final <T> ArgumentAcceptingOptionSpec<T> withValuesConvertedBy(ValueConverter<T> aConverter)
```
    Specifies a converter to use to translate arguments of this spec's option into Java objects. This is useful when converting to types that do not have the requisite factory method or constructor for ofType(Class).
    
    Invoking this method will trump any previous calls to this method or to ofType(Class).
    
    Type Parameters:
    
    T - represents the runtime class of the desired option argument type
    
    Parameters:
    
    aConverter - the converter to use
    
    Returns:
    
    self, so that the caller can add clauses to the fluent interface sentence
    
    Throws:
    
    java.lang.NullPointerException - if the converter is null
  - describedAs
```
public final ArgumentAcceptingOptionSpec<V> describedAs(java.lang.String description)
```
    Specifies a description for the argument of the option that this spec represents. This description is used when generating help information about the parser.
    
    Parameters:
    
    description - describes the nature of the argument of this spec's option
    
    Returns:
    
    self, so that the caller can add clauses to the fluent interface sentence
  - withValuesSeparatedBy
```
public final ArgumentAcceptingOptionSpec<V> withValuesSeparatedBy(char separator)
```
    Specifies a value separator for the argument of the option that this spec represents. This allows a single option argument to represent multiple values for the option. For example:
```
   
   parser.accepts( "z" ).withRequiredArg()
       .withValuesSeparatedBy( ',' );
   OptionSet options = parser.parse( new String[] { "-z", "foo,bar,baz", "-z",
       "fizz", "-z", "buzz" } );
   
 
```
    Then options.valuesOf( "z" ) would yield the list [foo, bar, baz, fizz, buzz].
    
    You cannot use Unicode U+0000 as the separator.
    Parameters:
    
    separator - a character separator
    
    Returns:
    
    self, so that the caller can add clauses to the fluent interface sentence
    
    Throws:
    
    java.lang.IllegalArgumentException - if the separator is Unicode U+0000
  - withValuesSeparatedBy
```
public final ArgumentAcceptingOptionSpec<V> withValuesSeparatedBy(java.lang.String separator)
```
    Specifies a value separator for the argument of the option that this spec represents. This allows a single option argument to represent multiple values for the option. For example:
```
   
   parser.accepts( "z" ).withRequiredArg()
       .withValuesSeparatedBy( ":::" );
   OptionSet options = parser.parse( new String[] { "-z", "foo:::bar:::baz", "-z",
       "fizz", "-z", "buzz" } );
   
 
```
    Then options.valuesOf( "z" ) would yield the list [foo, bar, baz, fizz, buzz].
    
    You cannot use Unicode U+0000 in the separator.
    Parameters:
    
    separator - a string separator
    
    Returns:
    
    self, so that the caller can add clauses to the fluent interface sentence
    
    Throws:
    
    java.lang.IllegalArgumentException - if the separator contains Unicode U+0000
  - defaultsTo
```
public ArgumentAcceptingOptionSpec<V> defaultsTo(V value,
                                                 V... values)
```
    Specifies a set of default values for the argument of the option that this spec represents.
    
    Parameters:
    
    value - the first in the set of default argument values for this spec's option
    
    values - the (optional) remainder of the set of default argument values for this spec's option
    
    Returns:
    
    self, so that the caller can add clauses to the fluent interface sentence
    
    Throws:
    
    java.lang.NullPointerException - if value, values, or any elements of values are null
  - defaultsTo
```
public ArgumentAcceptingOptionSpec<V> defaultsTo(V[] values)
```
    Specifies a set of default values for the argument of the option that this spec represents.
    
    Parameters:
    
    values - the set of default argument values for this spec's option
    
    Returns:
    
    self, so that the caller can add clauses to the fluent interface sentence
    
    Throws:
    
    java.lang.NullPointerException - if values or any elements of values are null
  - required
```
public ArgumentAcceptingOptionSpec<V> required()
```
    Marks this option as required. An OptionException will be thrown when OptionParser.parse(java.lang.String...) is called, if an option is marked as required and not specified on the command line.
