Method Details

argument

public SubsequenceInputTypeStrategy.SubsequenceStrategyBuilder argument(ArgumentTypeStrategy argumentTypeStrategy)

Defines that we expect a single argument at the next position.

argument

public SubsequenceInputTypeStrategy.SubsequenceStrategyBuilder argument(String argumentName,
 ArgumentTypeStrategy argumentTypeStrategy)

Defines that we expect a single named argument at the next position.

subsequence

public SubsequenceInputTypeStrategy.SubsequenceStrategyBuilder subsequence(InputTypeStrategy inputTypeStrategy)

Defines a common InputTypeStrategy for the next arguments. Given input strategy must expect a constant number of arguments. That means that both the minimum and maximum number of arguments must be defined and equal to each other.

If you need a varying logic use finishWithVarying(InputTypeStrategy).

finishWithVarying

public InputTypeStrategy finishWithVarying(InputTypeStrategy inputTypeStrategy)

Defines a common InputTypeStrategy for the next arguments. Given input strategy must expect a varying number of arguments. That means that the maximum number of arguments must not be defined.

finish

public InputTypeStrategy finish()

Constructs the given strategy.
