Salesforce Schedule Manager

Benefits

1. You don't need to create new schedulable class every time when you want to schedule a new batch.
2. You don't need to duplicate start and stop logic.

Examples

For example we have a batch class

global class BatchExample implements Database.Batchable<SObject> {

    global final String query;
    
    global BatchExample() {
        query = '<YOUR_QUERY_GOES_HERE>';
    }

    global Database.QueryLocator start(Database.BatchableContext BC) {
        return Database.getQueryLocator(query);
    }

    global void execute(Database.BatchableContext BC, List<sObject> scope) {
        <YOUR_LOGIC_GOES_HERE>
    }

    global void finish(Database.BatchableContext BC) {

    }

}

Everything that you need it just implements Executable interface and define logic for execute() method

global class BatchExample implements Database.Batchable<SObject>, Executable {

    global final String query;
    
    global BatchExample() {
        query = '<YOUR_QUERY_GOES_HERE>';
    }

    global Database.QueryLocator start(Database.BatchableContext BC) {
        return Database.getQueryLocator(query);
    }

    global void execute(Database.BatchableContext BC, List<sObject> scope) {
        <YOUR_LOGIC_GOES_HERE>
    }
    
    global void execute() {
         Database.executeBatch(this);
    }
    
    global String getJobName() {
        return <JOB_NAME>;
    }

    global void finish(Database.BatchableContext BC) {

    }

}

To schedule BatchExample class you just need to

   new ScheduleManager(new AccountContactNullValuesBatch()).scheduleDailyAt(12);
