converter

问题 I have a <h:selectOneMenu> that has <f:selectItems> with CategoryHistory objects loaded in it. I only show the Date date field as itemLabel . That works but I want to format the date: I created a converter that extends javax.faces.convert.DateTimeConverter and change the fields in the constructor. But my dates only show in default format :( DateAndTimeConverter.java import javax.faces.bean.ManagedBean; import javax.faces.convert.Converter; import javax.faces.convert.DateTimeConverter; import

问题 I need to convert GPS coordinates from WGS84 to decimal using Lua. I am sure it's been done before, so I am looking for a hint to a code snippet. corrected question: Code to convert DMS (Degress Minutes Seconds) to DEG ((decimal) Degrees) in Lua? examples: Vienna: dms: 48°12'30" N 16°22'28" E or Zurich: dms: 47°21'7" N 8°30'37" E The difficulty I find is to get the numbers out of these strings. Especially how to handle the signs for degree (°) minutes (') and seconds ("). So that I would have

问题 I have problems implementing a custom DependencyObject: I need a converter which sets or unsets a enum flag in a bound property. Therefore I created a IValueConverter derieved from FrameworkElement with two DependencyProperties: Flag (the flag which is set/unset by the converter) and Flags (the value/property to modify). The parent UserControl (Name = EnumerationEditor) provides the property to which the converter is bound. A ListBox generates CheckBoxes and the converter instances which are

问题 After read this article i have a question: In the exapmle in this link there is explanation hot to convert 192.168.25.234 into equivalent IPv6 address so in the example this address become C0A8:19EA and it says that this can be written into the following 128-Bit IPv6 link-local address: FE80:0000:0000:0000:0000:0000:C0A8:19EA or FE80::C0A8:19EA So my question is how C0A8:19EA become FE80:0000:0000:0000:0000:0000:C0A8:19EA ? 回答1: The C0, A8, 19 and EA are just 192, 168, 25 and 234 displayed in

问题 I have a simple AttributeConverter implementation in which I try to inject an object which have to provide the conversion logic, but @Inject seem not to work for this case. The converter class looks like this: @Converter(autoApply=false) public class String2ByteArrayConverter implements AttributeConverter<String, byte[]> { @Inject private Crypto crypto; @Override public byte[] convertToDatabaseColumn(String usrReadable) { return crypto.pg_encrypt(usrReadable); } @Override public String

问题 I am a seasoned Python developer and have come to love a lot of its conveniences. I have actually known C# for some time but recently have gotten into some more advanced coding. What I'm wondering is if there's a way to "parse" a byte array in C# into a set of (differently sized) items. Imagine we have this: Python: import struct byteArray = "\xFF\xFF\x00\x00\x00\xFF\x01\x00\x00\x00" numbers = struct.unpack("<LHL",byteArray) print numbers[0] # 65535 print numbers[1] # 255 print numbers[2] # 1

问题 I recently migrated my JSF app(using primefaces) from glassfish 3.1 to tomcat7 server. Previously passing the enum value as string to managed bean methods through actionlistener attribute worked(without the need for a converter to convert string to enum) but now it fails with javax.el.MethodNotFoundException . JSF page: <h:form> <h:outputLabel value="Title"/><br/> <p:inputText value="#{lobController.current.title}"/> <p:commandButton action="#{lobController.create('CAR')}" value="Post"/> </h

问题 I am using aqueduct web api framework to support my flutter app. In my api backend I need to connect local network socket services. My problem is that I can't return the exact string (in tr). S o, How can I convert string to utf8 in Dart? Example: @httpGet Future<Response> getLogin() async { Socket.connect('192.168.1.22’, 1024).then((socket) async { socket.listen((data) { // Expected return is: 1:_:2:_:175997:_:NİYAZİ TOROS print(new String.fromCharCodes(data).trim()); xResult = new String
