/**
 * 
 * The interface ServiceBuilderExtension provides an extension point to
 * org.apache.axis2.deployment.Deployer interface. During the deployment, a
 * Deployer invoke all ServiceBuilderExtension instances associated with it and
 * receive a list of org.apache.axis2.description.AxisService generated by one
 * of above ServiceBuilderExtension instances.
 * 
 * 
 * 
 * It is possible to register ServiceBuilderExtension for a
 * org.apache.axis2.deployment.Deployer through the axis2.xml configuration file
 * or one can can set ServiceBuilderExtension programtically.
 * 
 * 
 * 
 * Example
 * 
 * 
 * 
 * 
 * {@code
 *           
 *              
 *              
 *               
 *       }
 *  
 * 
 * 
 * 
 * 
 * 
 * To use ServiceBuilderExtension a custom Deployer must be extended from org.apache.axis2.deployment.AbstractDeployer 
 * class where org.apache.axis2.deployment.AbstractDeployer class register ServiceBuilderExtensions with underline Deployer
 * instance. 
 * 
 * 
 * Within deploy() method it is expected to call org.apache.axis2.deployment.AbstractDeployer#executeServiceBuilderExtensions
 * method to receive  list of AxisService instances generated by ServiceBuilderExtensions.
 * 
 * 
 *  For a given deploymentFile, if a ServiceBuilderExtension could create a AxisService then 
 *  stop execution of other ServiceBuilderExtensions registered and return the AxisService immediately 
 *  to the base Deployer for the further processing.    
 * 
 * 
 * 
 * @since 1.7.0
