OptionsResolverInterface | addAllowedTypes(array $allowedTypes) Adds allowed types for a list of options. | |

bool | isKnown(string $option) Returns whether an option is known. | |
bool | isRequired(string $option) Returns whether an option is required. | |
array | resolve(array $options = array()) Returns the combination of the default and the passed options. |
Sets default option values.
The options can either be values of any types or closures that evaluate the option value lazily. These closures must have one of the following signatures:
function (Options $options)
function (Options $options, $value)
The second parameter passed to the closure is the previously set default value, in case you are overwriting an existing default value.
The closures should return the lazily created option value.
array | $defaultValues | A list of option names as keys and default values or closures as values. |
OptionsResolverInterface | The resolver instance. |
Replaces default option values.
Old defaults are erased, which means that closures passed here cannot access the previous default value. This may be useful to improve performance if the previous default value is calculated by an expensive closure.
array | $defaultValues | A list of option names as keys and default values or closures as values. |
OptionsResolverInterface | The resolver instance. |
Sets optional options.
This method declares valid option names without setting default values for them. If these options are not passed to {@link resolve()} and no default has been set for them, they will be missing in the final options array. This can be helpful if you want to determine whether an option has been set or not because otherwise {@link resolve()} would trigger an exception for unknown options.
array | $optionNames | A list of option names. |
OptionsResolverInterface | The resolver instance. |
Sets required options.
If these options are not passed to {@link resolve()} and no default has been set for them, an exception will be thrown.
array | $optionNames | A list of option names. |
OptionsResolverInterface | The resolver instance. |
Sets allowed values for a list of options.
array | $allowedValues | A list of option names as keys and arrays with values acceptable for that option as values. |
OptionsResolverInterface | The resolver instance. |
InvalidOptionsException | If an option has not been defined (see {@link isKnown()}) for which an allowed value is set. |
Adds allowed values for a list of options.
The values are merged with the allowed values defined previously.
array | $allowedValues | A list of option names as keys and arrays with values acceptable for that option as values. |
OptionsResolverInterface | The resolver instance. |
InvalidOptionsException | If an option has not been defined (see {@link isKnown()}) for which an allowed value is set. |
Sets allowed types for a list of options.
array | $allowedTypes | A list of option names as keys and type names passed as string or array as values. |
OptionsResolverInterface | The resolver instance. |
InvalidOptionsException | If an option has not been defined for which an allowed type is set. |
Adds allowed types for a list of options.
The types are merged with the allowed types defined previously.
array | $allowedTypes | A list of option names as keys and type names passed as string or array as values. |
OptionsResolverInterface | The resolver instance. |
InvalidOptionsException | If an option has not been defined for which an allowed type is set. |
Sets normalizers that are applied on resolved options.
The normalizers should be closures with the following signature:
function (Options $options, $value)
The second parameter passed to the closure is the value of the option.
The closure should return the normalized value.
array | $normalizers | An array of closures. |
OptionsResolverInterface | The resolver instance. |
Returns whether an option is known.
An option is known if it has been passed to either {@link setDefaults()}, {@link setRequired()} or {@link setOptional()} before.
string | $option | The name of the option. |
bool | Whether the option is known. |
Returns whether an option is required.
An option is required if it has been passed to {@link setRequired()}, but not to {@link setDefaults()}. That is, the option has been declared as required and no default value has been set.
string | $option | The name of the option. |
bool | Whether the option is required. |
Returns the combination of the default and the passed options.
array | $options | The custom option values. |
array | A list of options and their values. |
InvalidOptionsException | If any of the passed options has not been defined or does not contain an allowed value. |
MissingOptionsException | If a required option is missing. |
OptionDefinitionException | If a cyclic dependency is detected between two lazy options. |
