        public boolean isHa()
        Will the verticle(s) be deployed as HA (highly available) ?
        Returns:
        true if HA, false otherwise

      • setHa

        public DeploymentOptions setHa​(boolean ha)
        Set whether the verticle(s) will be deployed as HA.
        Parameters:
        ha - true if to be deployed as HA, false otherwise

        a reference to this, so the API can be used fluently

      • getInstances

        public int getInstances()
        Get the number of instances that should be deployed.
        Returns:
        the number of instances

      • setInstances

        public DeploymentOptions setInstances​(int instances)
        Set the number of instances that should be deployed.
        Parameters:
        instances - the number of instances
        Returns:
        a reference to this, so the API can be used fluently

      • getWorkerPoolName

        public String getWorkerPoolName()
        Returns:
        the worker pool name

      • setWorkerPoolName

        public DeploymentOptions setWorkerPoolName​(String workerPoolName)
        Set the worker pool name to use for this verticle. When no name is set, the Vert.x worker pool will be used, when a name is set, the verticle will use a named worker pool.
        Parameters:
        workerPoolName - the worker pool name
        Returns:
        a reference to this, so the API can be used fluently

      • getWorkerPoolSize

        public int getWorkerPoolSize()
        Get the maximum number of worker threads to be used by the worker pool when the verticle is deployed with a setWorkerPoolName(java.lang.String).

        Worker threads are used for running blocking code and worker verticles.

        When the verticle does not use a named worker pool, this option has no effect.

        Returns:
        the maximum number of worker threads

      • setWorkerPoolSize

        public DeploymentOptions setWorkerPoolSize​(int workerPoolSize)
        Set the maximum number of worker threads to be used by the Vert.x instance.

        When the verticle does not use a named worker pool, this option has no effect.

        Parameters:
        workerPoolSize - the number of threads
        Returns:
        a reference to this, so the API can be used fluently

      • getMaxWorkerExecuteTime

        public long getMaxWorkerExecuteTime()
        Get the value of max worker execute time, in maxWorkerExecuteTimeUnit.

        Vert.x will automatically log a warning if it detects that worker threads haven't returned within this time.

        This can be used to detect where the user is blocking a worker thread for too long. Although worker threads can be blocked longer than event loop threads, they shouldn't be blocked for long periods of time.

        When the verticle does not use a named worker pool, this option has no effect.

        Returns:
        The value of max worker execute time, the default value of setMaxWorkerExecuteTimeUnit(java.util.concurrent.TimeUnit) maxWorkerExecuteTimeUnit is TimeUnit.NANOSECONDS

      • getMaxWorkerExecuteTimeUnit

        public TimeUnit getMaxWorkerExecuteTimeUnit()
        When the verticle does not use a named worker pool, this option has no effect.
        Returns:
        the time unit of maxWorkerExecuteTime

      • setMaxWorkerExecuteTimeUnit

        public DeploymentOptions setMaxWorkerExecuteTimeUnit​(TimeUnit maxWorkerExecuteTimeUnit)
        Set the time unit of maxWorkerExecuteTime

        When the verticle does not use a named worker pool, this option has no effect.

        Parameters:
        maxWorkerExecuteTimeUnit - the time unit of maxWorkerExecuteTime
        Returns:
        a reference to this, so the API can be used fluently

      • getClassLoader

        public ClassLoader getClassLoader()
        Returns:
        the classloader used for deploying the Verticle

      • setClassLoader

        public DeploymentOptions setClassLoader​(ClassLoader classLoader)
        Set the classloader to use for deploying the Verticle.

        The VerticleFactory will use this classloader for creating the Verticle and the Verticle Context will set this classloader as context classloader for the tasks execution on context.

        By default no classloader is required and the deployment will use the current thread context classloader.

        Parameters:
        classLoader - the loader to use
        Returns:
        a reference to this, so the API can be used fluently

      • toJson

        public JsonObject toJson()
        Convert this to JSON
        Returns:
        the JSON
