java - JCR basic concepts -


I am working with Magnolia CMS recently, which is to use JCR.

The problem I have is JCR Data Corruption and I came to know that I had very little knowledge of troubleshooting this situation.

My understanding of JCR is as follows:

  1. JCR is a specification, there are several implementations
  2. JackBabit is a JCR implementation
    3. <

Now my questions are

  1. How can a JCR be stored? Back up and restore?
  2. Is there any special device that can be tried to check and correct the integrity of a given JCR? I'm playing a bit with Tomeiro.
  3. Is there any special source of information / tutorials that I should read to get the full and appropriate understanding of ZCR technology?

Update:

I have some other questions:

  1. If a given JCR implementation stores content on a database , Then I can hope for all the content
  2. Currently we have a JCR repo which is accessed by three different webserver accessed, I understand that JCR speck is in this situation And this is an inconsistency on content due to concurrent writing access. The policy of protection to prevent. Is it true?
  3. To be specific, The problem we had experienced was a reference to a node B with a node, but node B is not being accessed, using a Groove script Later, we managed to remove the node B (which appears in an inconsistent state), however, how can we get all the references to node B (probably not only this node referred to, but node c). What happened because JCR repo was corrupted? , BTW We also tried to use force, see the detection check, autorer and capable competence flags, did not fix this problem.

Thanks

Your understanding is correct JCR: this is a specification Which has been implemented by many projects (including Jacobbitt, Modsap, Alfresco, Exo, etc.). In fact, there are many versions of JCR (1.0, 2.0 and very soon 2.1), and all implementations do not support all JCR versions.

(Full disclosure: I founder and lead of modShap.)

There is no standard and universal way to back up a JCR repository, but many implementations provide self-arrangement For example, if everything is stored in a DBMS, then you can use the DBMS backup and restore the feature. JackBeit has its own, as it does.

What kind of integrity are you investigating, and how do the Tormimo do this? The JCR implementation should not allow any material to be protected, which violates defined constraints (for example, node type definitions with property and hair node definitions), and these limits (for different degrees) how these node definitions Can be changed.

I do not know any great JCR books or online resources, but see more of this.

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
