How to skip invalid characters in stream in Java/Scala? -

-

उदाहरण के लिए मेरे पास कोड है 

  source.fromFile (नया फ़ाइल (पथ), "UTF-8")। GetLines ()   
 और यह अपवाद फेंकता  
  थ्रेड में अपवाद "मुख्य" java.nio.charset.MalformedInputException: इनपुट लंबाई = 1 java.nio.charset.CoderResult.throwException (CoderResult.java माह 60) पर sun.nio.cs.StreamDecoder.implRead (StreamDecoder.java319)   
 मैं डॉन 'कोई बात नहीं है अगर कुछ लाइनें नहीं पढ़ीं, लेकिन अमान्य वर्णों को कैसे छोड़ें और रीडिंग लाइनों को जारी रखने के लिए?   
 
 
 आप जिस तरह से वर्णसेट डिकोडिंग को कॉल करके अमान्य इनपुट को नियंत्रित कर सकते हैं, उसे प्रभावित कर सकते हैं।  
 <आम तौर पर  आपको कभी भी  वर्णसेटडिकोडर  ऑब्जेक्ट सीधे नहीं दिखाई देगा, क्योंकि यह आपके लिए पर्दे के पीछे बनाया जाएगा इसलिए यदि आपको इसे एक्सेस करने की आवश्यकता है, तो आपको एपीआई का उपयोग करने की आवश्यकता होगी जो आपको सीधे  CharsetDecoder  को निर्दिष्ट करने के बजाय (केवल एन्कोडिंग नाम या  Charset ) की अनुमति देता है। / P> 
 इस तरह के एपीआई का सबसे बुनियादी उदाहरण है:  
  InputStream in = ...; वर्णसेटडिकोडर डिकोडर = स्टैंडर्डचर्सेट्स.यूटीएफ_8.न्यूडीकोडर (); decoder.onMalformedInput (CodingErrorAction.IGNORE); रीडर रीडर = नए इनपुटस्ट्रीम रीडर (इन, डिकोडर);   
 ध्यान दें कि यह कोड जावा 7 वर्ग का उपयोग करता है, पहले के संस्करणों के लिए आप उसे (या इसके उपयोग से) प्रतिस्थापित कर सकते हैं।

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered. Especially when trying to connect like the example for Mono Touch string dbName = path. Cobain (environment.

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
