VMGenericsAndAnnotations

final public class VMGenericsAndAnnotations (Code)

Provides the methods to get signatures used to encode Java programming language type information such as generic type and method declarations and parameterized types.

Provides also the methods to get annotations and their elements values.

This class must be implemented according to the common policy for porting interfaces - see the porting interface overview for more detailes.

Method Summary
native public static Annotation[]	getDeclaredAnnotations(long id) This method satisfies the requirements of the specification for the Field.getDeclaredAnnotations Field.getDeclaredAnnotations() , Method.getDeclaredAnnotations Method.getDeclaredAnnotations() , Constructor.getDeclaredAnnotationsConstructor.getDeclaredAnnotations() methods. Parameters: id - an identifier of the caller (Field, or Method,or Constructor type).
native public static Annotation[]	getDeclaredAnnotations(Class clss) This method satisfies the requirements of the specification for the Class.getDeclaredAnnotations Class.getDeclaredAnnotations() .
native public static Object	getDefaultValue(long id) This method satisfies the requirements of the specification for the Method.getDefaultValue Method.getDefaultValue() method.
native public static Annotation[][]	getParameterAnnotations(long id) This method satisfies the requirements of the specification for the Method.getParameterAnnotations Method.getParameterAnnotations() and Constructor.getParameterAnnotations Constructor.getParameterAnnotations() methods. Parameters: id - an identifier of the caller (annotated element of the Method or Constructor type) class.
native public static String	getSignature(long id) This method returns the String representation of a Signature attribute corresponding to Method , Constructor or Field object declaration. Parameters: id - an identifier of a reflection member.
native public static String	getSignature(Class cls) This method returns the String representation of a Signature attribute corresponding to Class object declaration. Parameters: cls - a class to be reflected.

Method Detail

getDeclaredAnnotations
native public static Annotation[] getDeclaredAnnotations(long id)(Code)
	This method satisfies the requirements of the specification for the Field.getDeclaredAnnotations Field.getDeclaredAnnotations() , Method.getDeclaredAnnotations Method.getDeclaredAnnotations() , Constructor.getDeclaredAnnotationsConstructor.getDeclaredAnnotations() methods. Parameters: id - an identifier of the caller (Field, or Method,or Constructor type). all annotations directly present on this element or zero-sized array if there are no annotations. throws: TypeNotPresentException - if enum-valued or nested annotation member (of an annotation) refers to a class that is not accessible. throws: AnnotationFormatError - if reading an annotation from a class file determines that the annotation is malformed.

getDeclaredAnnotations
native public static Annotation[] getDeclaredAnnotations(Class clss)(Code)
	This method satisfies the requirements of the specification for the Class.getDeclaredAnnotations Class.getDeclaredAnnotations() . Parameters: clss - annotated element of the Class type all annotations directly present on this element or zero-sized array if there are no annotations. throws: TypeNotPresentException - if enum-valued or nested annotation member (of an annotation) refers to a class that is not accessible. throws: AnnotationFormatError - if reading an annotation from a class file determines that the annotation is malformed.

getDefaultValue
native public static Object getDefaultValue(long id)(Code)
	This method satisfies the requirements of the specification for the Method.getDefaultValue Method.getDefaultValue() method. But it takes one additional id parameter. Parameters: id - an identifier of the caller (annotated element of the Method type) class. the default value for the annotation member represented by thisMethod instance or null. throws: TypeNotPresentException - if the annotation is of type Class andno definition can be found for the default class value

getParameterAnnotations
native public static Annotation[][] getParameterAnnotations(long id)(Code)
	This method satisfies the requirements of the specification for the Method.getParameterAnnotations Method.getParameterAnnotations() and Constructor.getParameterAnnotations Constructor.getParameterAnnotations() methods. Parameters: id - an identifier of the caller (annotated element of the Method or Constructor type) class. an array of arrays that represent the annotations on the formalparameters, in declaration order, of the method represented by this Method object. Returns an array of length zero if the underlying method has no parameters. If the method has a parameter or more, a nested array of lengthzero is returned for each parameter with no annotations. throws: TypeNotPresentException - if Class-valued member (of an annotation)referring to a class that is not accessible in this VM.

getSignature
native public static String getSignature(long id)(Code)
	This method returns the String representation of a Signature attribute corresponding to Method , Constructor or Field object declaration. Parameters: id - an identifier of a reflection member. the String representation of a Signature attribute or null if a caller's declaration does not use any generics.

getSignature
native public static String getSignature(Class cls)(Code)
	This method returns the String representation of a Signature attribute corresponding to Class object declaration. Parameters: cls - a class to be reflected. the String representation of a Signature attribute or null if a caller's declaration does not use any generics.
