java.lang.Objectorg.mule.impl.model.AbstractComponent
org.mule.impl.model.seda.SedaComponent
A Seda component runs inside a Seda Model and is responsible for managing a Seda Queue and thread pool for a Mule sevice component. In Seda terms this is equivilent to a stage.
Field Summary | |
protected boolean |
componentPerRequest
If this is set to true a new component will be created for every request. |
protected MuleProxy |
componentProxy
Is created only if component pooling is turned off on the SEDAModel. |
protected String |
descriptorQueueName
|
protected boolean |
enablePooling
Whether component objects should be pooled or a single instance should be used. |
static String |
POOLING_PROFILE_PROPERTY
|
protected PoolingProfile |
poolingProfile
The pooling configuration used when initialising the component described by this descriptor. |
protected ObjectPool |
proxyPool
A pool of available Mule proxies. |
static String |
QUEUE_PROFILE_PROPERTY
|
protected QueueProfile |
queueProfile
The queuing profile for events received for this component. |
protected int |
queueTimeout
The time out used for taking from the Seda Queue. |
