public boolean equals(Object obj)

Compares based on the executable and the index.

public int hashCode()

Returns a hash code based on the executable's hash code and the index.

public boolean isNamePresent()

Returns true if the parameter has a name according to the class file; returns false otherwise. Whether a parameter has a name is determined by the MethodParameters attribute of the method which declares the parameter.

public String toString()

Returns a string describing this parameter. The format is the modifiers for the parameter, if any, in canonical order as recommended by The Java Language Specification, followed by the fully-qualified type of the parameter (excluding the last [] if the parameter is variable arity), followed by "..." if the parameter is variable arity, followed by a space, followed by the name of the parameter.

public Executable getDeclaringExecutable()

Returns the Executable declaring this parameter.

public int getModifiers()

Returns the Java language modifiers for the parameter represented by this object.

public Set<AccessFlag> accessFlags()

Returns an unmodifiable set of the access flags for the parameter represented by this object, possibly empty.

public String getName()

Returns the name of the parameter. If the parameter's name is present, then this method returns the name provided by the class file. Otherwise, this method synthesizes a name of the form argN, where N is the index of the parameter in the descriptor of the method which declares the parameter.

public Type getParameterizedType()

Returns a Type object that identifies the parameterized type for the parameter represented by this Parameter object.

public Class<?> getType()

Returns a Class object that identifies the declared type for the parameter represented by this Parameter object.

public AnnotatedType getAnnotatedType()

Returns an AnnotatedType object that represents the use of a type to specify the type of the formal parameter represented by this Parameter.

public boolean isImplicit()

Returns true if this parameter is implicitly declared in source code; returns false otherwise.

public boolean isSynthetic()

Returns true if this parameter is neither implicitly nor explicitly declared in source code; returns false otherwise.

public boolean isVarArgs()

Returns true if this parameter represents a variable argument list; returns false otherwise.

public <T extends Annotation> T getAnnotation(Class<T> annotationClass)

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.

public <T extends Annotation> T[] getAnnotationsByType(Class<T> annotationClass)

Returns annotations that are associated with this element. If there are no annotations associated with 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.

public Annotation[] getDeclaredAnnotations()

Returns annotations that are directly present on this element. This method ignores inherited annotations. If there are no annotations directly present on 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.

public <T extends Annotation> T getDeclaredAnnotation(Class<T> annotationClass)

Returns this element's annotation for the specified type if such an annotation is directly present, else null. This method ignores inherited annotations. (Returns null if no annotations are directly present on this element.)

Note that any annotation returned by this method is a declaration annotation.

public <T extends Annotation> T[] getDeclaredAnnotationsByType(Class<T> annotationClass)

Returns this element's annotation(s) for the specified type if such annotations are either directly present or indirectly present. This method ignores inherited annotations. If there are no specified annotations directly or indirectly present on this element, the return value is an array of length 0. The difference between this method and AnnotatedElement.getDeclaredAnnotation(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 if one is present. 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.

public Annotation[] getAnnotations()

Returns annotations that are present on this element. If there are no annotations present on 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.
