Class ezcReflectionParameter

The ezcReflectionParameter class retrieves information about a function's or method's parameters and their types.

Extends the ReflectionParameter class to provide type information using PHPDoc annotations.

Methods

export

static mixed export( mixed $function , mixed $parameter , [boolean $return = false] )

Exports a reflection object.

Returns the output if TRUE is specified for $return, printing it otherwise. This is purely a wrapper method, which calls the corresponding method of the parent class.

Parameters:

Name	Type	Description
`$function`	mixed	Function or Method
`$parameter`	mixed	Parameter
`$return`	boolean	Whether to return (TRUE) or print (FALSE) the output

Redefinition of:

Method	Description
`ReflectionParameter::export ( $function, $parameter, [$return = ] )`

__construct

ezcReflectionParameter __construct( string|array $functionOrMethod , $parameterPositionNameOrSource , [string $type = null] , integer|string|ReflectionParameter $parameter )

Constructor

If called with a ReflectionParameter instance as second argument the, first argument should be a string identifying the type of the parameter.

Parameters:

Name	Type	Description
`$functionOrMethod`	string\|array	The function, method or type of the parameter given as function name, array($classname, $method), or array($object, $method)
`$parameter`	integer\|string\|ReflectionParameter	Position (starting at 0), name, or ReflectionParameter instance of the parameter to introspect.
`$type`	string	Type of the parameter given in form of the type name.
`$parameterPositionNameOrSource`

Exceptions:

Type	Description
`ReflectionException`	in case the given method or function does not exist.

Redefinition of:

Method	Description
`ReflectionParameter::constructor __construct ( $function, $parameter )`

allowsNull

boolean allowsNull( )

Returns whether NULL is allowed as this parameters's value

Redefinition of:

Method	Description
`ReflectionParameter::allowsNull ( )`

forwardCallToReflectionSource

mixed forwardCallToReflectionSource( string $method , [mixed[] $arguments = array()] )

Forwards a method invocation to either the reflection source passed to the constructor of this class when creating an instance or to the parent class.

This method is part of the dependency injection mechanism and serves as a helper for implementing wrapper methods without code duplication.

Parameters:

Name	Type	Description
`$method`	string	Name of the method to be invoked
`$arguments`	mixed[]	Arguments to be passed to the method

getClass

ezcReflectionClass|NULL getClass( )

Returns reflection object identified by type hinting or NULL if there is no hint

This method does not rely on type annotations. That gives users the freedom to decide on whether they want to trust the type annotations, i.e., by calling getType(), or only PHP's type hinting, which is the sole data source for this method.

Exceptions:

Type	Description
`ReflectionException`	if a parameter uses 'self' or 'parent' as type hint, but function is not a class member, if a parameter uses 'parent' as type hint, although class does not have a parent, or if the class does not exist

Redefinition of:

Method	Description
`ReflectionParameter::getClass ( )`

getDeclaringClass

ezcReflectionClass getDeclaringClass( )

Returns in which class this parameter is defined (not the type hint of the parameter)

Redefinition of:

Method	Description
`ReflectionParameter::getDeclaringClass ( )`

getDeclaringFunction

ezcReflectionFunction|ezcReflectionMethod getDeclaringFunction( )

Returns the function or method declaring this parameter

Redefinition of:

Method	Description
`ReflectionParameter::getDeclaringFunction ( )`

getDefaultValue

mixed getDefaultValue( )

Returns the default value of this parameter or throws an exception

Redefinition of:

Method	Description
`ReflectionParameter::getDefaultValue ( )`

getName

string getName( )

Returns this parameters's name

Redefinition of:

Method	Description
`ReflectionParameter::getName ( )`

getPosition

integer getPosition( )

Returns whether this parameter is an optional parameter

Redefinition of:

Method	Description
`ReflectionParameter::getPosition ( )`

getType

ezcReflectionType getType( )

Returns the type of this parameter in form of an ezcReflectionType

A valid type hint for the parameter will be preferred over a type annotation.

Exceptions:

Type	Description
`ReflectionException`	if a parameter uses 'self' or 'parent' as type hint, but function is not a class member, if a parameter uses 'parent' as type hint, although class does not have a parent, or if the class does not exist

isArray

boolean isArray( )

Returns whether parameter MUST be an array

Redefinition of:

Method	Description
`ReflectionParameter::isArray ( )`

isDefaultValueAvailable

boolean isDefaultValueAvailable( )

Returns whether the default value of this parameter is available

Redefinition of:

Method	Description
`ReflectionParameter::isDefaultValueAvailable ( )`

isOptional

boolean isOptional( )

Returns whether this parameter is an optional parameter

Redefinition of:

Method	Description
`ReflectionParameter::isOptional ( )`

isPassedByReference

boolean isPassedByReference( )

Returns whether this parameters is passed to by reference

Redefinition of:

Method	Description
`ReflectionParameter::isPassedByReference ( )`

__call

mixed __call( string $method , array $arguments )

Use overloading to call additional methods of the ReflectionParameter instance given to the constructor.

Parameters:

Name	Type	Description
`$method`	string	Method to be called
`$arguments`	array	Arguments that were passed

__toString

string __toString( )

Returns a string representation

Redefinition of:

Method	Description
`ReflectionParameter::__toString ( )`
