restriction

问题 Given the following example: <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:complexType name="Book" abstract="true"> <xs:sequence> <xs:element name="titel" type="xs:string"> </xs:element> <xs:element name="bookCode" type="BookEnum"/> </xs:sequence> </xs:complexType> <xs:complexType name="Lyric"> <xs:complexContent> <xs:extension base="Book"> <xs:sequence> <xs:element name="author" type="xs:string"> </xs:element> </xs:sequence> </xs:extension> </xs:complexContent> </xs:complexType

问题 I'm currently playing a bit with the OWL and especially with restrictions. I'm trying to create a query that does the following: Suppose that I have a class 'Cinema' that has a property 'movies' (that contains objects of type 'Movie'). The class 'Movie' contains a property named 'genre'. Now I want to create a class ActionCinemas that only has movies with the genre 'action'. I'm really not sure how to do this. I was thinking about doing something with intersections or the cardinality but I'm

问题 Python's threading documentation states: All import attempts must be completed before the interpreter starts shutting itself down. This can be most easily achieved by only performing imports from non-daemon threads created through the threading module. Daemon threads and threads created directly with the thread module will require some other form of synchronization to ensure they do not attempt imports after system shutdown has commenced. Failure to abide by this restriction will lead to

问题 I have this error called Inconsistent accessibility: field type 'world' is less accessible than field 'frmSplashScreen' In my code there is a public partial class called frmSplashScreen There is also a public class called world The line that caused the error was: private world currentWorld; The above line is in the class frmSplashScreen What is causing the problem? 回答1: Generally this happens because your field is private . You must change it to public : public world currentWorld; For more on

问题 Browsers have a per-host limit regarding number of parallel XHR (about 6 nowadays). Does this restriction apply to multiplexed HTTP/2 connections? 回答1: Browsers impose a per-domain limit of 6-8 connections when using HTTP/1.1, depending on the browser implementation. This allows at most 6-8 concurrent requests per domain. With HTTP/2, browsers open only 1 connection per domain. However, thanks to the multiplexing feature of the HTTP/2 protocol, the number of concurrent requests per domain is

问题 I have list of category. I need a list of category by excluding 2,3 row. Can we achieve through hibernate by using Criteria and Restriction? 回答1: Your question is somewhat unclear. Assuming "Category" is a root entity and "2,3" are ids (or values of some property of the category") you can exclude them using the following: Criteria criteria = ...; // obtain criteria from somewhere, like session.createCriteria() criteria.add( Restrictions.not( // replace "id" below with property name, depending

问题 I need to write an XSD schema with a restriction on a field, to ensure that the value of the field does not contain the substring FILENAME at any location. For example, all of the following must be invalid: FILENAME ORIGINFILENAME FILENAMETEST 123FILENAME456 None of these values should be valid. In a regular expression language that supports negative lookahead, I could do this by writing /^((?!FILENAME).)*$ but the XSD pattern language does not support negative lookahead. How can I implement

问题 Is it possible to make a restriction in XSD document to other element value. For example, I have country and state elements. And if country is equal USA then I need to restrict state element value for specified enumeration otherwise state can be just a fixed length string. Example of current XSD which is restrict state to enumeration all the time: <xsd:simpleType name="country"> <xsd:restriction base="xsd:string"> <xsd:enumeration value="ABW"/> <xsd:enumeration value="AFG"/> <xsd:enumeration

问题 For example, I have three classes: Flock, Bird, Velocity. I also have two properties: hasMember (the domain is Flock, range is Bird), and hasAttribute (the domain is Bird, and the range is Velocity). Now I want to add a EquivalentClass restriction to Flock class as the definition. Let consider a very simple definition: in a flock, all birds have the same velocity. How to express this in OWL? 回答1: Warning: this answer is in fact incorrect, please look at the comments to see why. To the

问题 If I go to "Settings - Data Usage" and press the "Properties" I can activate "Restrict Background Data", using a Samsung Galaxy S2 (i9105P) with Android 4.1.2. Is there any way I can do this programmatically, both on and off? I only want to activate/deactivate it under certain conditions (determined by my app) so I don't have to manually remember to activate it. PS: I searched the android.developer.com website, but with no success. 回答1: You can run this command in the command line svc data
