We can define dynamic methods in a class as follows: Suppose we have injected a method name .clone([boolean] clearTime) in Date which clones the date object and returns the cloned one. This method takes an boolean argument argument too. We can do it as follows: (See inline comments for description) [java] //First we...
GDSL Scripts are based on two main concepts: contexts and contributors. Hence we will discuss about these in detail here. In GroovyDSL context is an entity which is supposed to give an answer to the question "Where?" this behavior will be available. Contexts are first-order citizens in GroovyDSL, so they may be stored in local...
hi, Suppose we have used method missing in our code and we want to give syntax-hinting for these methods then we can go as follows: Suppose we have this class which implements method missing: [java] class Pixel { def Top def Left def Color def methodMissing(String name, args) { //...
hi, Very often we use delegates in our closure calls. It would be great if we could get code-hinting in the closure via the delegates. Now let us take a very simple scenario, where we made a method "with" which delegates the delegate objet to closure and runs it. [java] class Delegator { static def...
hi, Sometimes we need to add specific methods in the closures which are passed to methods with a particular name. This can be simply done as follows Suppose we need to add the method named "setHeaders(Map headers)" in all closures passed to method with name "withREST" [java] //Get the context for all closures def...
hi, Sometimes we need to add specific properties in the closures which are passed to methods with a particular name. This can be simply done as follows Suppose we need to add the property named requestMethod of type String in all closures passed to method with name "withREST" [java] //Get the context for all...
hi, If we want to contribute to classes which matches a particular path/name pattern, then we can use PSI Class patterns to do it. the code is as follows: [java] import com.intellij.patterns.PsiJavaPatterns import com.intellij.patterns.PlatformPatterns //get the context of all files, and enable path matching....
Hi, Sometimes we need to contribute dynamically using current target class type. Lets take the example of .get() and .list() methods of Grails domain class. The signature of each method is as follows: public <DomainClassType> get(Long id) , Example: DemoClass.get(1) will return an object of "DemoClass" ...
Hi, I have been using the Grails mail plugin for a while now, this plugin injects a method named "sendMail" to all controllers and services. Our aim will be to provide auto-completes for this method and the closure inside. The GDSL Script is as follows: [java] import com.intellij.patterns.PsiJavaPatterns ...
Hi, Here i will illustrate how you can get the code of a method within GDSL Script: The script is as follows: [java] import com.intellij.patterns.PsiJavaPatterns import com.intellij.patterns.PlatformPatterns def mongoContext = context( ctype:...
Hi, Here is an example which uses a lot of gdsl concepts. This example tries to simulate injecting properties to Domains. The Example is as follows: (The code is self explanatory and can be used as a reference) [java] import com.intellij.patterns.PsiJavaPatterns import com.intellij.patterns.PlatformPatterns ...
Well This is something awesome and can increase the performance of the project when used wisely. using the groovy .memoize() we can ask closures to perform kind of caching. This can boost up the performance of the system. _ Note: This feature is available in groovy 1.8+ Well Let me Explain this Using Examples Now suppose i...
