Urlvalidator java

If this option is included then fragments are flagged as illegal. Enabling this option will let any scheme pass validation. This was originally based org. The validation is modified by passing in options in the schemes argument. Parameters: schemes - Pass in one or more URL schemes to consider valid.

Passing in a null will default to " http,https,ftp " being used. If a non- null scheme is specified, then all valid schemes must be specified.

Parameters: options - The options should be set using the public constants declared in this class. To set multiple options you simply add them together. This method is public because it is directly used in tests. Parameters: value - The value validation is being performed on. A null value is considered invalid. If schemes[] was initialized to non- nullthen only those schemes are allowed. Note that this is slightly different than for the constructor. Parameters: scheme - The scheme to validate.

An authority is the combination of host name and port. A null authority value is considered invalid. Parameters: authority - an authority value to validate Returns: true if authority host name and port is valid. Parameters: path - a path value to validate. Returns: true if path is valid. If the flag is not a power of 2 ie. Parameters: flag - flag value to check. All rights reserved. Object org. Allows all validly-formatted schemes to pass validation instead of supplying a set of valid schemes.

Constructs a UrlValidator with the given String array of scheme options. Constructs a UrlValidator with the given scheme and validation options see class description. Checks if the field isn't null and if length of the field is greater than zero, not including whitespace. Returns true if the given fragment is null or fragments are allowed.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Example of usage: Construct a UrlValidator with valid schemes of "http", and "https". Allows all validly formatted schemes to pass validation instead of supplying a set of valid schemes. This enables a broad-brush check, for complex local machine name validation requirements you should create your validator with a RegexValidator instead UrlValidator RegexValidator, long. Checks if a field has a valid url address. Note that the method calls isValidAuthority which checks that the domain is valid.

Validate scheme. If schemes[] was initialized to a non null, then only those schemes are allowed. Otherwise the default schemes are "http", "https", "ftp".

Matching is case-blind. Returns true if the authority is properly formatted. An authority is the combination of hostname and port. A null authority value is considered invalid. Note: this implementation validates the domain unless a RegexValidator was provided.

Returns true if the path is valid. A null value is considered invalid. UrlValidator Create a UrlValidator with default properties.Ok, so it is valid Java, but it shouldn't be. The key is that it's not really relying on the return type, but on the erased Generics parameter. This wouldn't work on a non-static method, and is explicitly forbidden on a non-static method.

Attempting to do so in a class would fail due to the extra issues, the first being that a typical class isn't final as the class Class is. It's an inconsistency in an otherwise rather consistent language. TI'll go out on a limb and say that it should be illegal, even if technically allowed. It doesn't really add anything to the readability of the language, and it adds scant little to the ability to solve meaningful problems.

The only meaningful problem it seems to solve is whether you are familiar enough with the language to know when it's core tenets seem to be violated by the language's internal inconsistencies in resolving type erasure, generics, and the resulting method signatures.

That means that both of your "f" methods will have the same signature but different return types. Return type can't be used to differentiate methods, because doing so will fail when you return into a common super-type; like:. Have you tried capturing the returned values into variables? Perhaps the compiler has optimized out things in such a way that it's not stepping on the right error code.

It would be interesting to know what the JLS is saying about it. From what I can tell the. If the return type would be the same, then the descriptors would be the same and the methods would be indistinguishable after the type erasure hence it doesn't work with void either.

While I find this practice a little questionable, I must say I find it kind of cool that you can do this, and think that generics should have been designed to be able to work like this in the first place yes, I know that would create problems with backwards compatibility.

It depends upon how you wish to call these methods. If you wish to call these methods from other Java source codethen it is considered invalid for reasons illustrated in Edwin's answer. This is a limitation of the Java Language. However, not all classes need to be generated from Java source code consider all the languages that use the JVM as their runtime: JRuby, Jython, etc At the bytecode levelthe JVM can disambiguate the two methods because the bytecode instructions specify the return type they are expecting.

For example, here is a class written in Jasmin that can call either of these methods:. It turns out the Sun compiler is generating the bytecode necessary to disambiguate the methods see instructions 12 and 31 in the last method. The Java Language Specification suggests that this may, in fact, be valid Java source code. It is possible that no method is the most specific, because there are two or more methods that are maximally specific.

In this case:. Adam Paynter: Your bolded text does not matter, because it is only a case when two methods are override-equivalent, which Dan showed was not the case. Thus, the determining factor must be if the JLS takes generic types into account when determining most specific method.

Java type inference what's going on when you call static, generic methods like Array. This paper from has a very interesting description of some of the issues and how it might be fixed:. Well, if I understand bullet point three correctly in the first list from section 8. It's the spec that really answers this question, and not the observed behavior of compiler X or IDE X.

All we can say by looking at the tools is how the author of the tool interpreted the spec. Is this valid Java?
