Class AbstractMethod

  • All Implemented Interfaces:
    AnnotatedElement
    Direct Known Subclasses:
    Constructor, Method
    public abstract class AbstractMethod
extends AccessibleObject
    This class represents an abstract method. Abstract methods are either methods or constructors.

      • accessFlags

        protected int accessFlags
        Bits encoding access (e.g. public, private) as well as other runtime specific flags

      • artMethod

        protected long artMethod
        The ArtMethod associated with this Method, requried for dispatching due to entrypoints Classloader is held live by the declaring class. Hidden to workaround b/16828157.

      • declaringClass

        protected Class<?> declaringClass
        Method's declaring class

      • declaringClassOfOverriddenMethod

        protected Class<?> declaringClassOfOverriddenMethod
        Overriden method's declaring class (same as declaringClass unless declaringClass is a proxy class)

      • dexMethodIndex

        protected int dexMethodIndex
        The method index of this method within its defining dex file

    • Constructor Detail

      • AbstractMethod

        protected AbstractMethod()

        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:

        Object.hashCode()

      • 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

        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.
