Method Detail

has

public boolean has(java.lang.String option)

Tells whether the given option was detected.

Parameters:

option - the option to search for

Returns:

true if the option was detected

See Also:

has(OptionSpec)

has

public boolean has(OptionSpec<?> option)

Tells whether the given option was detected.

This method recognizes only instances of options returned from the fluent interface methods.

Specifying a default argument value for an option does not cause this method to return true if the option was not detected on the command line.

Parameters:

option - the option to search for

Returns:

true if the option was detected

See Also:

has(String)

hasArgument

public boolean hasArgument(java.lang.String option)

Tells whether there are any arguments associated with the given option.

Parameters:

option - the option to search for

Returns:

true if the option was detected and at least one argument was detected for the option

See Also:

hasArgument(OptionSpec)

hasArgument

public boolean hasArgument(OptionSpec<?> option)

Tells whether there are any arguments associated with the given option.

This method recognizes only instances of options returned from the fluent interface methods.

Specifying a default argument value for an option does not cause this method to return true if the option was not detected on the command line, or if the option can take an optional argument but did not have one on the command line.

Parameters:

option - the option to search for

Returns:

true if the option was detected and at least one argument was detected for the option

Throws:

java.lang.NullPointerException - if option is null

See Also:

hasArgument(String)

valueOf

public java.lang.Object valueOf(java.lang.String option)

Gives the argument associated with the given option. If the option was given an argument type, the argument will take on that type; otherwise, it will be a String.

Specifying a default argument value for an option will cause this method to return that default value even if the option was not detected on the command line, or if the option can take an optional argument but did not have one on the command line.

Parameters:

option - the option to search for

Returns:

the argument of the given option; null if no argument is present, or that option was not detected

Throws:

java.lang.NullPointerException - if option is null

OptionException - if more than one argument was detected for the option

valueOf

public <V> V valueOf(OptionSpec<V> option)

Gives the argument associated with the given option.

This method recognizes only instances of options returned from the fluent interface methods.

Type Parameters:

V - represents the type of the arguments the given option accepts

Parameters:

option - the option to search for

Returns:

the argument of the given option; null if no argument is present, or that option was not detected

Throws:

OptionException - if more than one argument was detected for the option

java.lang.NullPointerException - if option is null

java.lang.ClassCastException - if the arguments of this option are not of the expected type

valuesOf

public java.util.List<?> valuesOf(java.lang.String option)

Gives any arguments associated with the given option. If the option was given an argument type, the arguments will take on that type; otherwise, they will be Strings.

Parameters:

option - the option to search for

Returns:

the arguments associated with the option, as a list of objects of the type given to the arguments; an empty list if no such arguments are present, or if the option was not detected

Throws:

java.lang.NullPointerException - if option is null

valuesOf

public <V> java.util.List<V> valuesOf(OptionSpec<V> option)

Gives any arguments associated with the given option. If the option was given an argument type, the arguments will take on that type; otherwise, they will be Strings.

This method recognizes only instances of options returned from the fluent interface methods.

Type Parameters:

V - represents the type of the arguments the given option accepts

Parameters:

option - the option to search for

Returns:

the arguments associated with the option; an empty list if no such arguments are present, or if the option was not detected

Throws:

java.lang.NullPointerException - if option is null

OptionException - if there is a problem converting the option's arguments to the desired type; for example, if the type does not implement a correct conversion constructor or method

nonOptionArguments

public java.util.List<java.lang.String> nonOptionArguments()

Returns:

the detected non-option arguments

equals

public boolean equals(java.lang.Object that)

Overrides:

equals in class java.lang.Object

hashCode
