()
Returns an array of
Class
objects that represent the formal parameter types, in declaration order, of the executable represented by this object. Returns an array of length 0 if the underlying executable takes no parameters. Note that the constructors of some inner classes may have an
implicitly declaredparameter in addition to explicitly declared ones. Also note that compact constructors of a record class may have
implicitly declaredparameters.
public abstract int getParameterCount()
Returns the number of formal parameters (whether explicitly declared or implicitly declared or neither) for the executable represented by this object.
()
Returns an array of
Type
objects that represent the formal parameter types, in declaration order, of the executable represented by this object. An array of length 0 is returned if the underlying executable takes no parameters. Note that the constructors of some inner classes may have an implicitly declared parameter in addition to explicitly declared ones. Compact constructors of a record class may also have
implicitly declaredparameters, but they are a special case and thus considered as if they had been explicitly declared in the source. Finally note that as a
modeling artifact
, the number of returned parameters can differ depending on whether or not generic information is present. If generic information is present, parameters explicitly present in the source or parameters of compact constructors of a record class will be returned. Note that parameters of compact constructors of a record class are a special case, as they are not explicitly present in the source, and its type will be returned regardless of the parameters being
implicitly declaredor not. If generic information is not present, implicit and synthetic parameters may be returned as well.
If a formal parameter type is a parameterized type, the Type object returned for it must accurately reflect the actual type arguments used in the source code. This assertion also applies to the parameters of compact constructors of a record class, independently of them being implicitly declared or not.
If a formal parameter type is a type variable or a parameterized type, it is created. Otherwise, it is resolved.
Types that represent the formal parameter types of the underlying executable, in declaration order
GenericSignatureFormatError - if the generic method signature does not conform to the format specified in The Java Virtual Machine Specification

MalformedParameterizedTypeException - if any of the underlying executable's parameter types refer to a parameterized type that cannot be instantiated for any reason
Returns an array of
Parameter
objects representing all the parameters to the underlying executable represented by this object. An array of length 0 is returned if the executable has no parameters.
The parameters of the underlying executable do not necessarily have unique names, or names that are legal identifiers in the Java programming language (JLS 3.8).

()
Returns an array of
Type
objects that represent the exceptions declared to be thrown by this executable object. Returns an array of length 0 if the underlying executable declares no exceptions in its
throws
clause.
If an exception type is a type variable or a parameterized type, it is created. Otherwise, it is resolved.

Executable, including any type parameters
public boolean isVarArgs()
Returns true if this executable was declared to take a variable number of arguments; returns false otherwise.
true if this executable was declared to take a variable number of arguments; returns false otherwise
public boolean isSynthetic()
Returns true if this executable is a synthetic construct; returns false otherwise.
isSynthetic in interface Member
()
Returns an array of arrays of
Annotation
s that represent the annotations on the formal parameters, in declaration order, of the
Executable
represented by this object. Synthetic and mandated parameters (see explanation below), such as the outer "this" parameter to an inner class constructor will be represented in the returned array. If the executable has no parameters (meaning no formal, no synthetic, and no mandated parameters), a zero-length array will be returned. If the
Executable
has one or more parameters, a nested array of length zero is returned for each parameter with no annotations. The annotation objects contained in the returned arrays are serializable. The caller of this method is free to modify the returned arrays; it will have no effect on the arrays returned to other callers. A compiler may add extra parameters that are implicitly declared in source ("mandated"), as well as parameters that are neither implicitly nor explicitly declared in source ("synthetic") to the parameter list for a method. See
Parameter
for more information.
Note that any annotations returned by this method are declaration annotations.
Returns this element's annotation for the specified type if such an annotation is
present, else null.
Note that any annotation returned by this method is a declaration annotation.
getAnnotation in interface AnnotatedElement
getAnnotation in class AccessibleObject
T - the type of the annotation to query for and return if present
annotationClass - the Class object corresponding to the annotation type
NullPointerException - if the given annotation class is null
Returns annotations that are
associatedwith this element. If there are no annotations
associatedwith this element, the return value is an array of length 0. The difference between this method and
AnnotatedElement.getAnnotation(Class)
is that this method detects if its argument is a
repeatable annotation type(JLS
9.6), and if so, attempts to find one or more annotations of that type by "looking through" a container annotation. The caller of this method is free to modify the returned array; it will have no effect on the arrays returned to other callers.
Note that any annotations returned by this method are declaration annotations.
getAnnotationsByType in interface AnnotatedElement
getAnnotationsByType in class AccessibleObject
T - the type of the annotation to query for and return if present
annotationClass - the Class object corresponding to the annotation type
NullPointerException - if the given annotation class is null
Returns annotations that are
directly presenton this element. This method ignores inherited annotations. If there are no annotations
directly presenton this element, the return value is an array of length 0. The caller of this method is free to modify the returned array; it will have no effect on the arrays returned to other callers.
Note that any annotations returned by this method are declaration annotations.
getDeclaredAnnotations in interface AnnotatedElement
getDeclaredAnnotations in class AccessibleObject
Returns an AnnotatedType object that represents the use of a type to specify the return type of the method/constructor represented by this Executable. If this Executable object represents a constructor, the AnnotatedType object represents the type of the constructed object. If this Executable object represents a method, the AnnotatedType object represents the use of a type to specify the return type of the method.
Executable
Returns an
AnnotatedType
object that represents the use of a type to specify the receiver type of the method/constructor represented by this
Executable
object. The receiver type of a method/constructor is available only if the method/constructor has a receiver parameter (JLS
8.4.1). If this
Executable
object
represents an instance method or represents a constructor of an inner member class, and the method/constructor
eitherhas no receiver parameter or has a receiver parameter with no annotations on its type, then the return value is an
AnnotatedType
object representing an element with no annotations. If this
Executable
object represents a static method or represents a constructor of a top level, static member, local, or anonymous class, then the return value is null.
Executable or null if this Executable can not have a receiver parameter
Returns an array of
AnnotatedType
objects that represent the use of types to specify formal parameter types of the method/constructor represented by this Executable. The order of the objects in the array corresponds to the order of the formal parameter types in the declaration of the method/constructor. Returns an array of length 0 if the method/constructor declares no parameters. Note that the constructors of some inner classes may have an
implicitly declaredparameter in addition to explicitly declared ones. Also note that compact constructors of a record class may have
implicitly declaredparameters.
Executable
Returns an array of AnnotatedType objects that represent the use of types to specify the declared exceptions of the method/constructor represented by this Executable. The order of the objects in the array corresponds to the order of the exception types in the declaration of the method/constructor. Returns an array of length 0 if the method/constructor declares no exceptions.
