Method Detail

getAnnotation

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

Description copied from interface: AnnotatedElement

Returns, for this element, the annotation with the specified type, or null if no annotation with the specified type is present (including inherited annotations).

Specified by:

getAnnotation in interface AnnotatedElement

Overrides:

getAnnotation in class AccessibleObject

Parameters:

annotationClass - the type of the annotation to search for

Returns:

the annotation with the specified type or null

getAccessFlags

public final int getAccessFlags()

getDexMethodIndex

public final int getDexMethodIndex()

Returns the index of this method's ID in its dex file.

getName

public abstract String getName()

Returns the name of the method or constructor represented by this instance.

Returns:

the name of this method

equals

public boolean equals(Object other)

Returns true if other has the same declaring class, name, parameters and return type as this method.

Overrides:

equals in class Object

Parameters:

other - the object to compare this instance with.

Returns:

true if the specified object is equal to this Object; false otherwise.

See Also:

Object.hashCode()

getDeclaredAnnotations

public Annotation[] getDeclaredAnnotations()

Description copied from interface: AnnotatedElement

Returns, for this element, all annotations that are explicitly declared (not inherited). If there are no declared annotations present, this method returns a zero length array.

Specified by:

getDeclaredAnnotations in interface AnnotatedElement

Overrides:

getDeclaredAnnotations in class AccessibleObject

Returns:

an array of annotations declared for this element

isAnnotationPresent

public boolean isAnnotationPresent(Class<? extends Annotation> annotationType)

Description copied from interface: AnnotatedElement

Indicates whether or not this element has an annotation with the specified annotation type (including inherited annotations).

Specified by:

isAnnotationPresent in interface AnnotatedElement

Overrides:

isAnnotationPresent in class AccessibleObject

Parameters:

annotationType - the type of the annotation to search for

Returns:

true if the annotation exists, false otherwise

getAnnotations

public Annotation[] getAnnotations()

Description copied from interface: AnnotatedElement

Returns, for this element, an array containing all annotations (including inherited annotations). If there are no annotations present, this method returns a zero length array.

Specified by:

getAnnotations in interface AnnotatedElement

Overrides:

getAnnotations in class AccessibleObject

Returns:

an array of all annotations for this element

getParameterAnnotations

public abstract Annotation[][] getParameterAnnotations()

Returns an array of arrays that represent the annotations of the formal parameters of this method. If there are no parameters on this method, then an empty array is returned. If there are no annotations set, then and array of empty arrays is returned.

Returns:

an array of arrays of Annotation instances

equalMethodParameters

protected boolean equalMethodParameters(Class<?>[] params)

compareParameters

protected int compareParameters(Class<?>[] params)
