The Apache PDFBox™ library is an open source Java tool for working with PDF documents. This project ... Extract Text . Extract Unicode text from PDF files. Since the CLR automatically calls a type s class constructor the first time code attempts to access a member of the class, the first time a thread queries Singleton s GetSingleton method, the CLR will automatically call the class constructor, which creates an instance of the object . Furthermore, the CLR already ensures that calls to a class constructor are thread safe . I explained all of this in 8 . The one downside of this approach is that the type constructor is called when any member of a class is first accessed . If the Singleton type defined some other static members, then the Singleton object would be created when any one of them was accessed . Some people work around this problem by defining nested classes . Let me show you a third way of producing a single Singleton object: find and replace text in pdf using java: Add Text to a PDF file - Aspose.

Apache PDFBox is an open source Java PDF library for working with PDF ... Features. PDF to text extraction; Merge PDF Documents; PDF Document Encryption/ ... IsInvariantToDuplicates: This is an optional property. For example, the MAX aggregate is invariant to duplicates, while SUM is not. IsInvariantToNulls: This is another optional property. It specifies whether the aggregate is invariant to NULLs. IsInvariantToOrder: This property is reserved for future use. It is currently ignored by the query processor. Therefore, order is currently not guaranteed. IsNullIfEmpty: This property indicates whether the aggregate will return a NULL if no values have been accumulated. 14. Add the aforementioned properties to your UDA by copying them from Listing 6-8. Your first UDA is now complete! 15. Listing 6-8 also has the code to implement a product UDA (CSProdAgg). Copy the complete code implementing CSProgAgg to your script. Note that this UDA involves handling of big integers only. Because the UDA internally deals only with value types, it can use native serialization. Native serialization requires that the StructLayoutAttribute be specified as StructLayout.LayoutKindSequential if the UDA is defined in a class and not a structure. Otherwise, the UDA implements the same four methods as your previous UDA. There is an additional check in the Accumulate method that prevents out-of-range values. 16. Finally, add the Visual Basic .NET version of both UDAs created so far: replace text in pdf using java PDFBox Example Code: How to Extract Text From PDF file with java

However, the call to Interlocked.CompareExchange ensures that only one of the references is ever published into the s_value field . Any object not rooted by this field will be garbage collected later on . Since, in most applications, it is unlikely that multiple threads will call GetSingleton at the same time, it is unlikely that more than one Singleton object will ever be created . Now it might upset you that multiple Singleton objects could be created, but there are many benefits to this code . First, it is very fast . Second, it never blocks a thread; if a thread pool thread is blocked on a Monitor or any other kernel-mode thread synchronization construct, then the thread pool creates another thread to keep the CPUs saturated with work . So now, another megabyte or more of memory is allocated and initialized and all the DLLs get a thread attach notification . With CompareExchange, this can never happen . Of course, you can use this technique only when the constructor has no side effects . The FCL offers two types that encapsulate the patterns described in this section . The generic System.Lazy class looks like this (some methods are not shown): java pdf to text library How to extract text from a PDF file with Apache PDFBox - Stack ...
