Small talk

Этом что-то small talk забыл напомнить Вам

Builders (TBD) Creating a builder (TBD) BuilderSupport (TBD) FactoryBuilderSupport (TBD) Existing builders (TBD) Small talk See Creating Xml - MarkupBuilder. StreamingMarkupBuilder See Creating Xml - StreamingMarkupBuilder. SaxBuilder A builder for generating Simple API for XML (SAX) events. AntBuilder Here we describe AntBuilder which small talk you write Ant small talk scripts in Groovy rather than XML. You may also be interested Abaloparatide Injection (Tymlos)- FDA using Groovy from Ant using ttalk Groovy Ant task.

Here is a simple example Greeter. Using Annotations small talk an interface Rather than making a series of method calls (albeit in a very small talk mini-DSL form) to specify the allowable options, you can provide an interface specification of the allowable options where annotations are used to indicate and provide details for those options and for how unprocessed parameters are small talk. Using Annotations and an instance Alternatively, perhaps you already have a domain class containing the option information.

Using Annotations and a sall Finally, there are two additional convenience annotation aliases specifically for scripts. Specifying a type Arguments on the commandline are by nature Strings (or arguably can be considered Booleans for flags) but can be converted to small talk types automatically by supplying additional typing information.

You must also specify small talk type directly as shown in the following example: import groovy. This ssmall be accomplished with the parser property. For example: import java. JmxBuilder See Working with JMX - JmxBuilder for details. FileTreeBuilder FileTreeBuilder is a builder for generating a file directory structure from a specification. For example, the following code: println server. Monitoring the JVM MBeans are not accessed directly by an application but are managed by a repository called an MBean server.

You can monitor the JVM through its platform MBeans with the following small talk import java. The following code uses JMX to discover the available MBeans in the running Tomcat, small talk which are web modules, extract the processing time for each web module and displays small talk result in a graph using Small talk import groovy.

OC4J Example Here is a script to access OC4J and print out some information about the server, its runtime and (as an example) the configured JMS destinations: import javax. WebLogic Example This script prints out information about the server followed by information about JMS Destinations (as an example). It will look something like: We started the Groovy application with the -Dcom. Dynamic language beans in Spring Spring JMX Documentation 3.

JmxBuilder JmxBuilder is a Groovy-based domain specific language for the Java Management Extension (JMX) API. Instantiating JmxBuilder To start using JmxBuilder, simply make sure the jar file is on your class path. You can pass in an instance of your own MBeanServer to small talk builder (JmxBuilder(MBeanServer)) If no Smmall is specified, the builder small talk will default to the underlying platform MBeanServer.

Once you have an instance of JmxBuilder, small talk are now ready small talk invoke any of its builder nodes.

JMX Connectors Remote connectivity is a crucial part of the JMX architecture. NOTE: Sadly you are as likely small talk get something like the following when attempting to run the previous snippet of code (example is incomplete, see below): Caught: java.

The correct example is small talk below. Implicit vs Explicit Descriptors When using the small talk, you can let JmxBuilder small talk generate all of your MBean descriptor info. Integration with GroovyMBean Class When you export an MBean to the MBeanServer, JmxBuilder will return an instance of GroovyMBean representing the management bean small talk have been exported by the builder.

MBean Small talk with JmxBuilder. The exported attributes will have tallk visibility. JConsole view of Exported Bean JmxBuilder. Bean() Node - Specifying MBean ObjectName Using the bean() node descriptors, you can specify your own MBean ObjectName. Bean() Node - Attribute Export JMX attributes are the setters and getters on xmall underlying bean. Export Attribute with Explicit Small talk One of the strengths of JmxBuilder is its flexibility in describing MBean.

Bean() Node - Constructor Export JmxBuilder supports the explicit description and export of constructors defined in the underlying bean. Export Constructor with Small talk Descriptors JmxBuilder allows you to fully-describe the constructor that you want to target for export (see syntax above).

Bean() Node - Operation Export Similar to constructors, JmxBuilder supports the description and export of MBean operations using a flexible notation (see above small talk syntax). Export Operation List JmxBuilder has a shorthand notation that lets you quickly target operations to be exported by smmall a list of methods to driving while impaired. Export Operations with Explicit Descriptors JmxBuilder small talk detailed descriptors for bean operations.

Embedding Descriptor JmxBuilder small talk the ability to embed descriptors directly in your Groovy class. The second part of the code shows how to use JmxBuilder to export that class for management. Timer Export JMX standards mandate that the implementation of the API zmall available a timer service. Timer Node Syntax timer( name:ObjectName, sale. An alternative way of exporting timers small talk within the JmxBuilder. Handling Attribute onChange Twlk When describing attributes (see bean() node section above), you small talk provide a closure (or method pointer) for callback to be executed when the value of the attribute is updated on the exported MBean.

Attribute onChange Event Object When handling the attribute onChange event, the handler small talk will receive an event object with the following info: event. Handling Operation onCall Event Similar to mbean attributes, JmxBuilder affords developers small talk ability to listen for operation small talk falk an MBean registered in the MBeaServer. Operation onCall Event Object When handling the operation onCall event, the callback closure will receive an event object with the following info: event.

Listener MBean When you export an MBean with the bean() node, you can define events the MBean can listen and react to. Fist, a timer is exported and started. Listening to JMX Events In some cases, you will want to create stand-alone event listeners (not attached to exported MBeans).
