ReflectionParameter 类

(PHP 5, PHP 7)

简介

ReflectionParameter 取回了函数或方法参数的相关信息。

要自行检查函数的参数，首先创建一个 ReflectionFunction 或 ReflectionMethod 的实例，然后使用它们的 ReflectionFunctionAbstract::getParameters() 方法来获取参数的数组。

ReflectionParameter implements Reflector {

/* 属性 */

public $name ;

/* 方法 */

public bool allowsNull ( void )

public bool canBePassedByValue ( void )

final private void __clone ( void )

public __construct ( string $function , string $parameter )

public static string export ( string $function , string $parameter [, bool $return ] )

public ReflectionClass getClass ( void )

public ReflectionClass getDeclaringClass ( void )

public ReflectionFunctionAbstract getDeclaringFunction ( void )

public mixed getDefaultValue ( void )

public string getDefaultValueConstantName ( void )

public string getName ( void )

public int getPosition ( void )

public ReflectionType getType ( void )

public bool hasType ( void )

public bool isArray ( void )

public bool isCallable ( void )

public bool isDefaultValueAvailable ( void )

public bool isDefaultValueConstant ( void )

public bool isOptional ( void )

public bool isPassedByReference ( void )

public bool isVariadic ( void )

public string __toString ( void )

}

ReflectionParameter::allowsNull — Checks if null is allowed
ReflectionParameter::canBePassedByValue — Returns whether this parameter can be passed by value
ReflectionParameter::__clone — Clone
ReflectionParameter::__construct — Construct
ReflectionParameter::export — Exports
ReflectionParameter::getClass — Get the type hinted class
ReflectionParameter::getDeclaringClass — Gets declaring class
ReflectionParameter::getDeclaringFunction — Gets declaring function
ReflectionParameter::getDefaultValue — Gets default parameter value
ReflectionParameter::getDefaultValueConstantName — Returns the default value's constant name if default value is constant or null
ReflectionParameter::getName — Gets parameter name
ReflectionParameter::getPosition — Gets parameter position
ReflectionParameter::getType — Gets a parameter's type
ReflectionParameter::hasType — Checks if parameter has a type
ReflectionParameter::isArray — Checks if parameter expects an array
ReflectionParameter::isCallable — Returns whether parameter MUST be callable
ReflectionParameter::isDefaultValueAvailable — Checks if a default value is available
ReflectionParameter::isDefaultValueConstant — Returns whether the default value of this parameter is constant
ReflectionParameter::isOptional — Checks if optional
