The various classes in Zend_Reflection mimic the API of PHP's Reflection API - with one important difference. PHP's Reflection API does not provide introspection into docblock annotation tags, nor into parameter variable types or return types. Zend_Reflection analyzes method docblock annotations to determine parameter variable types and the return type. Specifically, the @param and @return annotations are used. However, you can also check for any other annotation tags, as well as the standard "short" and "long" descriptions. Each reflection object in Zend_Reflection overrides the getDocblock() method to return an instance of Zend_Reflection_Docblock. This class provides introspection into the docblocks and annotation tags. Zend_Reflection_File is a new reflection class that allows introspection of PHP files. With it, you can retrieve the classes, functions, and global PHP code contained in the file. Finally, the various methods that return other reflection objects allow a second parameter, the name of the reflection class to use for the returned reflection object. Zend_Reflection_Docblock is the heart of Zend_Reflection's value-add over PHP's Reflection API. It provides the following methods: getContents(): docblockの完全な内容を返す getStartLine(): 定義されたファイル内での docblock開始位置を返す getEndLine(): 定義されたファイル内での docblock終了行を返す getShortDescription(): 短い、一行の説明を取得 (たいていはdocblockの最初の行) getLongDescription(): docblockの長い説明を取得 hasTag($name): 与えられた注釈タグが docblockにあるかどうか判断する。 getTag($name): Retrieve the given annotation tag reflection object, or a boolean false if it's not present. getTags($filter): Retrieve all tags, or all tags matching the given $filter string. The tags returned will be an array of Zend_Reflection_Docblock_Tag objects. Zend_Reflection_Docblock_Tag provides reflection for individual annotation tags. Most tags consist of only a name and a description. In the case of some special tags, the class provides a factory method for retrieving an instance of the appropriate class. The following methods are defined for Zend_Reflection_Docblock_Tag: factory($tagDocblockLine): instantiate the appropriate tag reflection class and return it. getName(): 注釈タグの名前を返す getDescription(): 注釈の説明を返す Zend_Reflection_Docblock_Tag_Param is a specialized version of Zend_Reflection_Docblock_Tag. The @param annotation tag description consists of the parameter type, variable name, and variable description. It adds the following methods to Zend_Reflection_Docblock_Tag: getType(): パラメータ変数の型を返す getVariableName(): パラメータ変数の名前を返す Like Zend_Reflection_Docblock_Tag_Param, Zend_Reflection_Docblock_Tag_Return is a specialized version of Zend_Reflection_Docblock_Tag. The @return annotation tag description consists of the return type and variable description. It adds the following method to Zend_Reflection_Docblock_Tag: getType(): 戻す型を返す Zend_Reflection_File provides introspection into PHP files. With it, you can introspect the classes, functions, and bare PHP code defined in a file. It defines the following methods: getFileName(): reflectionを使用したファイルの名前を取得 getStartLine(): ファイルの開始行を返す（常に１） getEndLine() 最終行、ファイル中の行数を取得 getDocComment($reflectionClass = 'Zend_Reflection_Docblock'): retrive the file-level docblock reflection object. getClasses($reflectionClass = 'Zend_Reflection_Class'): retrieve an array of reflection objects, one for each class defined in the file. getFunctions($reflectionClass = 'Zend_Reflection_Function'): retrieve an array of reflection objects, one for each function defined in the file. getClass($name = null, $reflectionClass = 'Zend_Reflection_Class'): retrieve the reflection object for a single class. getContents(): retrieve the full contents of the file. Zend_Reflection_Class extends ReflectionClass, and follows its API. It adds one additional method, getDeclaringFile(), which may be used to retrieve the Zend_Reflection_File reflection object for the defining file. Additionally, the following methods add an additional argument for specifying the reflection class to use when fetching a reflection object: getDeclaringFile($reflectionClass = 'Zend_Reflection_File') getDocblock($reflectionClass = 'Zend_Reflection_Docblock') getInterfaces($reflectionClass = 'Zend_Reflection_Class') getMethod($reflectionClass = 'Zend_Reflection_Method') getMethods($filter = -1, $reflectionClass = 'Zend_Reflection_Method') getParentClass($reflectionClass = 'Zend_Reflection_Class') getProperty($name, $reflectionClass = 'Zend_Reflection_Property') getProperties($filter = -1, $reflectionClass = 'Zend_Reflection_Property') Zend_Reflection_Extension extends ReflectionExtension, and follows its API. It overrides the following methods to add an additional argument for specifying the reflection class to use when fetching a reflection object: getFunctions($reflectionClass = 'Zend_Reflection_Function'): retrieve an array of reflection objects representing the functions defined by the extension. getClasses($reflectionClass = 'Zend_Reflection_Class'): retrieve an array of reflection objects representing the classes defined by the extension. Zend_Reflection_Function adds a method for retrieving the function return type, as well as overrides several methods to allow specifying the reflection class to use for returned reflection objects. getDocblock($reflectionClass = 'Zend_Reflection_Docblock'): retrieve the function docblock reflection object. getParameters($reflectionClass = 'Zend_Reflection_Parameter'): retrieve an array of all function parameter reflection objects. getReturn(): retrieve the return type reflection object. Zend_Reflection_Method mirrors Zend_Reflection_Function, and only overrides one additional method: getParentClass($reflectionClass = 'Zend_Reflection_Class'): retrieve the parent class reflection object. Zend_Reflection_Parameter adds a method for retrieving the parameter type, as well as overrides methods to allow specifying the reflection class to use on returned reflection objects. getDeclaringClass($reflectionClass = 'Zend_Reflection_Class'): get the declaring class of the parameter as a reflection object (if available). getClass($reflectionClass = 'Zend_Reflection_Class'): get the class of the parameter as a reflection object (if available). getDeclaringFunction($reflectionClass = 'Zend_Reflection_Function'): get the function of the parameter as a reflection object (if available). getType(): パラメータの型を取得 Zend_Reflection_Property overrides a single method in order to allow specifying the returned reflection object class: getDeclaringClass($reflectionClass = 'Zend_Reflection_Class'): retrieve the declaring class of the property as a reflection object.
