You can easily navigate the a Syntax Tree using LINQ. For example it is easy to get all the ClassDeclarationSyntax nodes (declared classes), that have a name starting with the letter A: var allClassesWithNameStartingWithA = syntaxRoot.DescendantNodes() .OfType<ClassDeclarationSyntax>()...

The CSharpSyntaxWalker class is out of the box implementation of the Visitor pattern, that we can use to traverse our Syntax Tree. Here is a simple example of a Syntax Walker that collects all the struct-s that have a name, starting with the letter A: public class StructCollector : CSharpSyntaxWa...

Prerequisite This guide assumes you have already used BuildTools and have run the Spigot server at least once. It also assumes that you have the Spigot-API jar file which we will use. 1) Start Eclipse; you may change the workspace location if desired. 2) Create a new Project Set the project na...

Inline expansion (also known as inlining) is compiler optimisation that replaces a call to a function with the body of that function. This saves the function call overhead, but at the cost of space, since the function may be duplicated several times. // source: int process(int value) { ret...

Replace operator: The -replace operator replaces a pattern in an input value using a regular expression. This operator uses two arguments (separated by a comma): a regular expression pattern and its replacement value (which is optional and an empty string by default). "The rain in Seattle&quo...

If you package your application in a jar using the maven-jar-plugin or the maven-assembly-plugin, an easy way to get the current pom version is to add an entry in the manifest, which is then available from Java. The secret is to set the addDefaultImplementationEntries flag to true (and the addDefau...

As this documentation explains, Sometimes a resource file will need to contain a value that can only be supplied at build time. To accomplish this in Maven, put a reference to the property that will contain the value into your resource file using the syntax ${<property name>}. The property ...

The other examples may be the best and most stable way to get a version number into an application statically. This answer proposes an alternative showing how to do it dynamically during runtime, using the maven maven-model library. Add the dependency: <dependency> <groupId>org.apac...

Design Patterns provide solutions to the commonly occurring problems in software design. The design patterns were first introduced by GoF(Gang of Four) where they described the common patterns as problems which occur over and over again and solutions to those problems. Design patterns have four ess...

package main import ( "fmt" "time" ) func say(s string) { for i := 0; i < 5; i++ { time.Sleep(100 * time.Millisecond) fmt.Println(s) } } func main() { go say("world") say("hello") } A goroutine ...

To initialize struct, you can do like this : public static void main (string[] args) { Value val = Value (typeof (int)); val.set_int (33); } But Vala brings another way to initialize values : public static void main (string[] args) { Value val = 33; } Your value is initializ...

This exemple shows how you can pass several types in function parameters : static void print_value (Value val) { print ("value-type : %s\n", val.type().name()); print ("value-content : %s\n\n", val.strdup_contents()); } public static void main (string[] args) { ...

it caused by your batch size too small, which lead to a lot of ROS Containers created and reach the limitation(1024 default). you should do defragment using TupleMover task(mergeout) before the error raised. To do troubleshooting: ROS Containers viewed from the projections. select * from STOR...
