__construct(mixed $options = null)

Initializes the constraint with options.

from Constraint
__set(string $option, mixed $value)

Sets the value of a lazily initialized option.

from Constraint
mixed __get(string $option)

Returns the value of a lazily initialized option.

from Constraint
addImplicitGroupName(string $group)

Adds the given group if this constraint is in the Default group.

from Constraint
string getDefaultOption()

from Constraint

Details

static string getErrorName(string $errorCode)

Returns the name of the given error code.

Parameters

string $errorCode The error code

Return Value

string The name of the error code

Exceptions

InvalidArgumentException If the error code does not exist

__construct(mixed $options = null)

Initializes the constraint with options.

You should pass an associative array. The keys should be the names of existing properties in this class. The values should be the value for these properties.

Alternatively you can override the method getDefaultOption() to return the name of an existing property. If no associative array is passed, this property is set instead.

You can force that certain options are set by overriding getRequiredOptions() to return the names of these options. If any option is not set here, an exception is thrown.

Parameters

mixed $options The options (as associative array) or the value for the default option (any other type)

Exceptions

InvalidOptionsException When you pass the names of non-existing options
MissingOptionsException When you don't pass any of the options returned by getRequiredOptions()
ConstraintDefinitionException When you don't pass an associative array, but getDefaultOption() returns null

__set(string $option, mixed $value)

Sets the value of a lazily initialized option.

Corresponding properties are added to the object on first access. Hence this method will be called at most once per constraint instance and option name.

Parameters

string $option The option name
mixed $value The value to set

Exceptions

InvalidOptionsException If an invalid option name is given

mixed __get(string $option)

Returns the value of a lazily initialized option.

Corresponding properties are added to the object on first access. Hence this method will be called at most once per constraint instance and option name.

Parameters

string $option The option name

Return Value

mixed The value of the option

Exceptions

InvalidOptionsException If an invalid option name is given

addImplicitGroupName(string $group)

Adds the given group if this constraint is in the Default group.

Parameters

string $group

string getDefaultOption()

Returns the name of the default option.

Override this method to define a default option.

Return Value

string

array getRequiredOptions()

Returns the name of the required options.

Override this method if you want to define required options.

Return Value

array

string validatedBy()

The validator must be defined as a service with this name.

Return Value

string

string|array getTargets()

Returns whether the constraint can be put onto classes, properties or both.

This method should return one or more of the constants Constraint::CLASSCONSTRAINT and Constraint::PROPERTYCONSTRAINT.

Return Value

string|array One or more constant values

array __sleep()

Optimizes the serialized value to minimize storage space.

Return Value

array The properties to serialize
