Constructor Detail

ArgGroupSpec

ArgGroupSpec(CommandLine.Model.ArgGroupSpec.Builder builder)

Method Detail

builder

public static CommandLine.Model.ArgGroupSpec.Builder builder()

Returns a new CommandLine.Model.ArgGroupSpec.Builder.

Returns:

a new ArgGroupSpec.Builder instance

builder

public static CommandLine.Model.ArgGroupSpec.Builder builder(CommandLine.Model.IAnnotatedElement annotatedElement)

Returns a new CommandLine.Model.ArgGroupSpec.Builder associated with the specified annotated element.

Parameters:

annotatedElement - the annotated element containing @Option and @Parameters

Returns:

a new ArgGroupSpec.Builder instance

exclusive

public boolean exclusive()

Returns whether this is a mutually exclusive group; true by default. If false, this is a co-occurring group. Ignored if validate() is false.

See Also:

CommandLine.ArgGroup.exclusive()

multiplicity

public CommandLine.Range multiplicity()

Returns the multiplicity of this group: how many occurrences it may have on the command line; "0..1" (optional) by default. A group can be made required by specifying a multiplicity of "1". For a group of mutually exclusive arguments, being required means that one of the arguments in the group must appear on the command line, or a MissingParameterException is thrown. For a group of co-occurring arguments, being required means that all arguments in the group must appear on the command line. Ignored if validate() is false.

See Also:

CommandLine.ArgGroup.multiplicity()

validate

public boolean validate()

Returns whether picocli should validate the rules of this group: for a mutually exclusive group this means that no more than one arguments in the group is specified on the command line; for a co-ocurring group this means that all arguments in the group are specified on the command line. true by default.

See Also:

CommandLine.ArgGroup.validate()

order
