Public Methods

Method	Description
__clone ( )
__toString ( ) : string	Return string representation of this parameter.
allowsNull ( ) : boolean	Does this method allow null for a parameter?
canBePassedByValue ( ) : boolean
createFromClassInstanceAndMethod ( object $instance, string $methodName, string $parameterName ) : ReflectionParameter	Create a reflection of a parameter using an instance
createFromClassNameAndMethod ( string $className, string $methodName, string $parameterName ) : ReflectionParameter	Create a reflection of a parameter using a class name
createFromNode ( BetterReflection\Reflector\Reflector $reflector, Param $node, ReflectionFunctionAbstract $function, integer $parameterIndex ) : ReflectionParameter
createFromSpec ( string[] \| string \| Closure $spec, string $parameterName ) : ReflectionParameter	Create the parameter from the given spec. Possible $spec parameters are:
export ( )
getClass ( ) : ReflectionClass \| null	Gets a ReflectionClass for the type hint (returns null if not a class)
getDeclaringClass ( ) : ReflectionClass \| null	Get the class from the method that this parameter belongs to, if it exists.
getDeclaringFunction ( ) : ReflectionFunctionAbstract	Get the function (or method) that declared this parameter.
getDefaultValue ( ) : mixed	Get the default value of the parameter.
getDefaultValueAsString ( ) : string	Get the default value represented as a string.
getDefaultValueConstantName ( ) : string
getDocBlockTypeStrings ( ) : string[]	Get the DocBlock type hints as an array of strings.
getDocBlockTypes ( ) : phpDocumentor\Reflection\Type[]	Get the types defined in the DocBlocks. This returns an array because the parameter may have multiple (compound) types specified (for example when you type hint pipe-separated "string\|null", in which case this would return an array of Type objects, one for string, one for null.
getName ( ) : string	Get the name of the parameter.
getPosition ( ) : integer	Find the position of the parameter, left to right, starting at zero.
getType ( ) : ReflectionType \| null	Get the ReflectionType instance representing the type declaration for this parameter
getTypeHint ( ) : phpDocumentor\Reflection\Type	Get the type hint declared for the parameter. This is the real type hint for the parameter, e.g. method(closure $someFunc) defined by the method itself, and is separate from the DocBlock type hints.
hasType ( ) : boolean	Does this parameter have a type declaration?
isArray ( ) : boolean	Is this parameter an array?
isCallable ( ) : boolean	Is this parameter a callable?
isDefaultValueAvailable ( ) : boolean	Does the parameter have a default, regardless of whether it is optional.
isDefaultValueConstant ( ) : boolean
isOptional ( ) : boolean	Is the parameter optional?
isPassedByReference ( ) : boolean	Is this parameter passed by reference (denoted by &$param).
isVariadic ( ) : boolean	Is this parameter a variadic (denoted by .
removeType ( )	Remove the parameter type declaration completely.
setType ( phpDocumentor\Reflection\Type $newParameterType )	Set the parameter type declaration.

Method Details

__clone() public method

public __clone ( )

__toString() public method

Return string representation of this parameter.

public __toString ( ) : string
return	string

allowsNull() public method

Does this method allow null for a parameter?

public allowsNull ( ) : boolean
return	boolean

canBePassedByValue() public method

public canBePassedByValue ( ) : boolean
return	boolean

createFromClassInstanceAndMethod() public static method

Create a reflection of a parameter using an instance

public static createFromClassInstanceAndMethod ( object $instance, string $methodName, string $parameterName ) : ReflectionParameter
$instance	object
$methodName	string
$parameterName	string
return	ReflectionParameter

createFromClassNameAndMethod() public static method

Create a reflection of a parameter using a class name

public static createFromClassNameAndMethod ( string $className, string $methodName, string $parameterName ) : ReflectionParameter
$className	string
$methodName	string
$parameterName	string
return	ReflectionParameter

createFromNode() public static method

public static createFromNode ( BetterReflection\Reflector\Reflector $reflector, Param $node, ReflectionFunctionAbstract $function, integer $parameterIndex ) : ReflectionParameter
$reflector	BetterReflection\Reflector\Reflector
$node	PhpParser\Node\Param
$function	ReflectionFunctionAbstract
$parameterIndex	integer
return	ReflectionParameter

createFromSpec() public static method

- [$instance, 'method'] - ['Foo', 'bar'] - ['foo'] - [function () }]

public static createFromSpec ( string[] \| string \| Closure $spec, string $parameterName ) : ReflectionParameter
$spec	string[] \| string \| Closure
$parameterName	string
return	ReflectionParameter

export() public static method

public static export ( )

getClass() public method

Gets a ReflectionClass for the type hint (returns null if not a class)

public getClass ( ) : ReflectionClass \| null
return	ReflectionClass \| null

getDeclaringClass() public method

This will return null if the declaring function is not a method.

public getDeclaringClass ( ) : ReflectionClass \| null
return	ReflectionClass \| null

getDeclaringFunction() public method

Get the function (or method) that declared this parameter.

public getDeclaringFunction ( ) : ReflectionFunctionAbstract
return	ReflectionFunctionAbstract

getDefaultValue() public method

Get the default value of the parameter.

public getDefaultValue ( ) : mixed
return	mixed

getDefaultValueAsString() public method

Get the default value represented as a string.

public getDefaultValueAsString ( ) : string
return	string

getDefaultValueConstantName() public method

public getDefaultValueConstantName ( ) : string
return	string

getDocBlockTypeStrings() public method

Get the DocBlock type hints as an array of strings.

public getDocBlockTypeStrings ( ) : string[]
return	string[]

getDocBlockTypes() public method

Get the types defined in the DocBlocks. This returns an array because the parameter may have multiple (compound) types specified (for example when you type hint pipe-separated "string|null", in which case this would return an array of Type objects, one for string, one for null.

getName() public method

Get the name of the parameter.

public getName ( ) : string
return	string

getPosition() public method

Find the position of the parameter, left to right, starting at zero.

public getPosition ( ) : integer
return	integer

getType() public method

(note: this has nothing to do with DocBlocks).

public getType ( ) : ReflectionType \| null
return	ReflectionType \| null

getTypeHint() public method

Get the type hint declared for the parameter. This is the real type hint for the parameter, e.g. method(closure $someFunc) defined by the method itself, and is separate from the DocBlock type hints.

hasType() public method

(note: this has nothing to do with DocBlocks).

public hasType ( ) : boolean
return	boolean

isArray() public method

Is this parameter an array?

public isArray ( ) : boolean
return	boolean

isCallable() public method

Is this parameter a callable?

public isCallable ( ) : boolean
return	boolean

isDefaultValueAvailable() public method

Note this is distinct from "isOptional" because you can have a default value, but the parameter not be optional. In the example, the $foo parameter isOptional() == false, but isDefaultValueAvailable == true

public isDefaultValueAvailable ( ) : boolean
return	boolean

isDefaultValueConstant() public method

public isDefaultValueConstant ( ) : boolean

isOptional() public method

Note this is distinct from "isDefaultValueAvailable" because you can have a default value, but the parameter not be optional. In the example, the $foo parameter isOptional() == false, but isDefaultValueAvailable == true
