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()

Returns the name of the class that validates this constraint.

By default, this is the fully qualified name of the constraint class suffixed with "Validator". You can override this method to change that behaviour.

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

string|null getHtmlPattern()

Converts the htmlPattern to a suitable format for HTML5 pattern.

Example: /^[a-z]+$/ would be converted to [a-z]+ However, if options are specified, it cannot be converted.

Pattern is also ignored if match=false since the pattern should then be reversed before application.

Return Value

string|null
