Method Details

choicesAndResults

VariableValueParameters.DynamicChoicesBuilder<T> choicesAndResults(Supplier<Map<String,? extends T>> choices)

Sets the parameter to get its choices from the supplied Map, where each choice is associated with its own object.

Parameters:

choices - A supplier that returns an appropriate map.

Returns:

This builder, for chaining

choices

VariableValueParameters.DynamicChoicesBuilder<T> choices(Supplier<? extends Collection<String>> choices)

Sets the parameter to get its choices from the supplied Collection.

Parameters:

choices - A supplier that returns the appropriate choices.

Returns:

This builder, for chaining

results

VariableValueParameters.DynamicChoicesBuilder<T> results(Function<String,? extends T> results)

Sets the function which defines what result is returned for a specified choice.

Parameters:

results - A function that returns the appropriate object for the provided choice

Returns:

This builder, for chaining

showInUsage

VariableValueParameters.DynamicChoicesBuilder<T> showInUsage(boolean showInUsage)

Sets what should happen if the usage of this parameter is requested.

If there are 5 or fewer choices available, and "showInUsage" is true, the choices will be shown in the command usage. Otherwise, the usage will only display only the key.

Parameters:

showInUsage - true if the choices should be shown

Returns:

This builder, for chaining

build

ValueParameter<T> build()

Tests for validity and creates this ValueParameter.

Specified by:

build in interface AbstractBuilder<T>

Returns:

The ValueParameter

Throws:

IllegalStateException - if no choices have been specified
