The Caching Pattern def obj = cache.get("myentry") if(!obj) { obj = ... // do some complex task to obtain obj cache.put("myentry", obj) } return obj However, given that you have the power of closures at your disposal, it makes more sense to take advantage of them to come up with a more elegant solution. Listing 13-23 shows how to implement caching of entire logical blocks using closures. Listing 13-23. Caching the Return Value of Blocks of Code Using Closures 1 import net.sf.ehcache.Ehcache 2 import net.sf.ehcache.Element 3 4 class CacheService { 5 ... 6 def cacheOrReturn(Serializable cacheKey, Closure callable) { 7 def entry = globalCache .get(cacheKey) .getValue() 8 if(!entry) { 9 entry = callable.call() 10 globalCache.put new Element(cacheKey, entry) 11 } 12 return entry 13 } 14 } To understand what the code is doing in Listing 13-23, let s step through it line by line. First, on line 7 an entry is obtained from the globalCache bean, which is an instance of the net.sf.ehcache.Ehcache class: 7 def entry = globalCache .get(cacheKey) .getValue() Notice how you can use Groovy s safe-dereference operator . to make sure that a NullPointerException is never thrown when accessing the value, even if the globalCache property is null! The get method of the globalCache instance returns a net.sf.ehcache. Element instance, which has a getValue() method you can call to obtain the cached value. Next on lines 8 and 9 the code checks that the returned value is null, and if it is, the passed closure is invoked, which returns the result that needs to be cached: 8 9 if(!entry) { def entry = callable.call() c# parse pdf itextsharp: C# Tutorial 51: Reading PDF File Using iTextSharp and show it in ... c# extract text from pdf GitHub - bubibubi/ExtractTablesFromPdf: Extract tables (and ...

In this C# tutorial you will learn to extract text from a PDF file into a new text file by using the PdfReaderContentParser and SimpleTextExtractionStragegy ... Now we need to tell Hibernate how to connect to the database and load the Address.hbm.xml class mapping in the SessionFactory. For this simple example we will do this directly in the Java code. Subsequent examples will use the preferred XML configuration file. Listing 4-4 shows how to create a Hibernate configuration object in code, add a Hibernate mapped class, and retrieve an instance of the SessionFactory from the configuration. When you invoke the addClass method of the Configuration class, passing the class object for the Address class (Address.class), Hibernate will look for a HBM file named Address.hbm.xml in the class path. So the simplest way to ensure that Hibernate will find your mappings is to place them in the same location as the class they map. Once you have a SessionFactory, working with your persistent objects is as simple as obtaining a Session and invoking methods on it. Replace the user name and password with that required for your database. Listing 4-4. Configuring Hibernate in Code Configuration config = new Configuration(). setProperty("hibernate.dialect", "org.hibernate.dialect.MySQLDialect"). setProperty("hibernate.connection.driver_class", "com.mysql.jdbc.Driver"). setProperty("hibernate.connection.url", "jdbc:mysql://localhost/techconf"). setProperty("hibernate.connection.username", "mydbuser"). setProperty("hibernate.connection.password", "mydbpassword"). setProperty("hibernate.show_sql", "true"); config.addClass(Address.class); SessionFactory factory = config.buildSessionFactory(); For example to create an Address object and save it to the database we take the following steps, reflected in Listing 4-5: 1. POJO is created and values are set. 2. SessionFactory is used to create a Session. 3. A Hibernate Transaction bound to the Session is started. 4. The object is saved using the Session persist method. 5. The Transaction is committed. 6. The Session is closed. extract images from pdf c#: Pdf parser Image extraction from pdf - C# Corner c# read pdf text itextsharp Extract and verify text from PDF with C# | Automation Rhapsody
