      • getAnnotationEntries

        public AnnotationEntry[] getAnnotationEntries()
        Gets annotations on the field or method.
        Returns:
        Annotations on the field or method.
        Since:
        6.0

        Parameters:
        tag - the attribute tag.
        Returns:
        Attribute for given tag, null if not found. Refer to Const.ATTR_UNKNOWN constants named ATTR_* for possible values.
        Since:
        6.10.0

      • getAttributes

        public final Attribute[] getAttributes()
        Gets the collection of object attributes.

      • getConstantPool

        public final ConstantPool getConstantPool()
        Gets the constant pool used by this object.

      • getGenericSignature

        public final java.lang.String getGenericSignature()
        Hunts for a signature attribute on the member and returns its contents. So where the 'regular' signature may be (Ljava/util/Vector;)V the signature attribute may in fact say 'Ljava/lang/Vector<Ljava/lang/String>;' Coded for performance - searches for the attribute only when requested - only searches for it once.
        Returns:
        the generic signature.
        Since:
        6.0

      • getSignature

        public final java.lang.String getSignature()
        Gets the string representation of object's type signature.
        Returns:
