Groovy Script Library - Problem creating class from working script

Hi,

The code for your class had some bugs in it.

Below is a simple implementation of a class that achieves what you want...

package groovyScripts.play;  // Change this to your package name.

class DOB {

    //Define our range.
    def start = Date.parse('yyyy-MM-dd', '2015-01-01')
    def end = Date.parse('yyyy-MM-dd', '2017-12-31')
    def random = new Random();

    def DOB() {
        // Constructor for the object.
        // nothing to do here, but constructors are useful for one-time set up tasks.

    }


    Date randomDate() {
        // This is the method we will call to get a random date.
        Range<Date> range = (this.start..this.end);
	def res = range.from + random.nextInt(range.to - range.from + 1)

        return res;
    }

}

Then, in your groovy script, you can create the object and call the mehtod...

def dobObject = new groovyScripts.play.DOB();  // remember to update the package

log.info(dobObject.randomDate());

Here's a more refined example of the class, which uses the constructor to set-up the object..

package groovyScripts.play;

class DOB {

    //Define our properties.
    def start = null;
    def end = null;
    def random = null;
    Range<Date> range = null;

    def DOB() {
        // Constructor for the object.
        // Let's set up what we can up front.
        this.start = Date.parse('yyyy-MM-dd', '2015-01-01')
        this.end = Date.parse('yyyy-MM-dd', '2017-12-31')
        this.random = new Random();       
        this.range = (this.start..this.end);
    }


    Date randomDate() {

	    def res = this.range.from + this.random.nextInt(this.range.to - this.range.from + 1)

        return res;
    }

}

You can even 'overload' the constructor so that you can pass in the range, should you want to override the defaults....

Here's the updated class...

package groovyScripts.play;

class DOB {

    //Define our range.
    def start = null;
    def end = null;
    def random = null;
    Range<Date> range = null;

    def DOB() {
        // Constructor for the object.
        // Let's set up what we can up front.
        this.start = Date.parse('yyyy-MM-dd', '2015-01-01')
        this.end = Date.parse('yyyy-MM-dd', '2017-12-31')
        this.random = new Random();       
        this.range = (this.start..this.end);
    }

    def DOB(start, end) {
        // Overloaded Constructor for the object.
        // Let's set up the object with passed in values.
        this.start = Date.parse('yyyy-MM-dd', start);
        this.end = Date.parse('yyyy-MM-dd', end);
        this.random = new Random();       
        this.range = (this.start..this.end);
    }

    Date randomDate() {

	    def res = this.range.from + this.random.nextInt(this.range.to - this.range.from + 1)

        return res;
    }

}

Usage example....

// Use the defaults in the class....
def dobObject = new groovyScripts.play.DOB();
log.info(dobObject.randomDate());

// Let's override the defaults....
def dobObject2 = new groovyScripts.az.play.DOB('1990-01-01',  '1990-12-31');
log.info(dobObject2.randomDate());
