public
bool
$templated
= false
a value indicating whether [[href]] refers to a URI or URI template.

$title
a label describing the link
$type

Methods
__call()
Calls the named method which is not a class method.
public
__call(string $name, array<string|int, mixed> $params) : mixed
Do not call this method directly as it is a PHP magic method that will be implicitly called when an unknown method is being invoked.
Parameters
- $name : string
-
the method name
- $params : array<string|int, mixed>
-
method parameters
Tags
Return values
mixed —the method return value
__construct()
Constructor.
public
__construct([array<string|int, mixed> $config = [] ]) : mixed
The default implementation does two things:
- Initializes the object with the given configuration
$config
. - Call [[init()]].
If this method is overridden in a child class, it is recommended that
- the last parameter of the constructor is a configuration array, like
$config
here. - call the parent implementation at the end of the constructor.
Parameters
- $config : array<string|int, mixed> = []
-
name-value pairs that will be used to initialize the object properties
__get()
Returns the value of an object property.
public
__get(string $name) : mixed
Do not call this method directly as it is a PHP magic method that
will be implicitly called when executing $value = $object->property;
.
Parameters
- $name : string
-
the property name
Tags
Return values
mixed —the property value
__isset()
Checks if a property is set, i.e. defined and not null.
public
__isset(string $name) : bool
Do not call this method directly as it is a PHP magic method that
will be implicitly called when executing isset($object->property)
.
Note that if the property is not defined, false will be returned.
Parameters
- $name : string
-
the property name or the event name
Tags
Return values
bool —whether the named property is set (not null).
__set()
Sets value of an object property.
public
__set(string $name, mixed $value) : mixed
Do not call this method directly as it is a PHP magic method that
will be implicitly called when executing $object->property = $value;
.
Parameters
- $name : string
-
the property name or the event name
- $value : mixed
-
the property value
Tags
__unset()
Sets an object property to null.
public
__unset(string $name) : mixed
Do not call this method directly as it is a PHP magic method that
will be implicitly called when executing unset($object->property)
.
Note that if the property is not defined, this method will do nothing. If the property is read-only, it will throw an exception.
Parameters
- $name : string
-
the property name
Tags
canGetProperty()
Returns a value indicating whether a property can be read.
public
canGetProperty(string $name[, bool $checkVars = true ]) : bool
A property is readable if:
- the class has a getter method associated with the specified name (in this case, property name is case-insensitive);
- the class has a member variable with the specified name (when
$checkVars
is true);
Parameters
- $name : string
-
the property name
- $checkVars : bool = true
-
whether to treat member variables as properties
Tags
Return values
bool —whether the property can be read
canSetProperty()
Returns a value indicating whether a property can be set.
public
canSetProperty(string $name[, bool $checkVars = true ]) : bool
A property is writable if:
- the class has a setter method associated with the specified name (in this case, property name is case-insensitive);
- the class has a member variable with the specified name (when
$checkVars
is true);
Parameters
- $name : string
-
the property name
- $checkVars : bool = true
-
whether to treat member variables as properties
Tags
Return values
bool —whether the property can be written
className()
Returns the fully qualified name of this class.
public
static className() : string
Tags
Return values
string —the fully qualified name of this class.
hasMethod()
Returns a value indicating whether a method is defined.
public
hasMethod(string $name) : bool
The default implementation is a call to php function method_exists()
.
You may override this method when you implemented the php magic method __call()
.
Parameters
- $name : string
-
the method name
Return values
bool —whether the method is defined
hasProperty()
Returns a value indicating whether a property is defined.
public
hasProperty(string $name[, bool $checkVars = true ]) : bool
A property is defined if:
- the class has a getter or setter method associated with the specified name (in this case, property name is case-insensitive);
- the class has a member variable with the specified name (when
$checkVars
is true);
Parameters
- $name : string
-
the property name
- $checkVars : bool = true
-
whether to treat member variables as properties
Tags
Return values
bool —whether the property is defined
init()
Initializes the object.
public
init() : mixed
This method is invoked at the end of the constructor after the object is initialized with the given configuration.
serialize()
Serializes a list of links into proper array format.
public
static serialize(array<string|int, mixed> $links) : array<string|int, mixed>
Parameters
- $links : array<string|int, mixed>
-
the links to be serialized
Return values
array<string|int, mixed> —the proper array representation of the links.
