OptionsResolverInterface ^deprecated

$this setDefaults(array $defaultValues)

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.

Parameters

array

$defaultValues

a list of option names as keys and default values or closures as values

Return Value

$this

$this replaceDefaults(array $defaultValues)

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.

Parameters

array

$defaultValues

a list of option names as keys and default values or closures as values

Return Value

$this

$this setOptional(array $optionNames)

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.

Parameters

array

$optionNames

A list of option names

Return Value

$this

$this setRequired(array $optionNames)

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.

Parameters

array

$optionNames

A list of option names

Return Value

$this

$this setAllowedValues(array $allowedValues)

Sets allowed values for a list of options.

Parameters

array

$allowedValues

a list of option names as keys and arrays with values acceptable for that option as values

Return Value

$this

Exceptions

InvalidOptionsException

if an option has not been defined (see {@link isKnown()}) for which an allowed value is set

$this addAllowedValues(array $allowedValues)

Adds allowed values for a list of options.

The values are merged with the allowed values defined previously.

Parameters

array

$allowedValues

a list of option names as keys and arrays with values acceptable for that option as values

Return Value

$this

Exceptions

InvalidOptionsException

if an option has not been defined (see {@link isKnown()}) for which an allowed value is set

$this setAllowedTypes(array $allowedTypes)

Sets allowed types for a list of options.

Parameters

array

$allowedTypes

a list of option names as keys and type names passed as string or array as values

Return Value

$this

Exceptions

InvalidOptionsException

if an option has not been defined for which an allowed type is set

$this addAllowedTypes(array $allowedTypes)

Adds allowed types for a list of options.

The types are merged with the allowed types defined previously.

Parameters

array

$allowedTypes

a list of option names as keys and type names passed as string or array as values

Return Value

$this

Exceptions

InvalidOptionsException

if an option has not been defined for which an allowed type is set

$this setNormalizers(array $normalizers)

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.

Parameters

array

$normalizers

An array of closures

Return Value

$this

bool isKnown(string $option)

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.

Parameters

string

$option

The name of the option

Return Value

bool	Whether the option is known

bool isRequired(string $option)

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.

Parameters

string

$option

The name of the option

Return Value

bool	Whether the option is required

array resolve(array $options = array())

Returns the combination of the default and the passed options.

Parameters

array

$options

The custom option values

Return Value

array

A list of options and their values

Exceptions

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
