COMPONENT_ID

static final java.lang.String COMPONENT_ID

A component property that contains the generated id for a component configuration. The value of this property must be of type Long.

The value of this property is assigned by Service Component Runtime when a component configuration is created. Service Component Runtime assigns a unique value that is larger than all previously assigned values since Service Component Runtime was started. These values are NOT persistent across restarts of Service Component Runtime.
