Example 25 with Binding

use of groovy.lang.Binding in project groovity by disney.

the class Groovity method load.

/**
 * This method is used to load an instance of a script without executing it, for example in order to use it as a library,
 * or to defer running it until a later time; instances are always Singletons within a binding scope, so repeated
 * calls to load the same script name with the same binding will return the same instance of the script.
 *
 * @param scriptName the path of the script to execute, e.g. /myFolder/myScript
 * @param binding the groovy binding to use as global variable scope
 * @return an instance of a script tied to the provided binding
 * @throws InstantiationException
 * @throws IllegalAccessException
 * @throws ClassNotFoundException
