Examples of org.apache.flume.conf.ComponentConfiguration

org.apache.flume.conf.ComponentConfiguration
Abstract implementation of the Component Configuration Manager. This class does the configuration in the object. The component specific versions, which inherit from this, create the configuration based on the config file. All subclasses of this class store properties of the component. The properties can be stored as properties in this
