Constructor Detail

FileEventActivitySource

public FileEventActivitySource(org.apache.commons.configuration2.Configuration conf,
                               EventManager eventManager,
                               Registry registry)
                        throws ConfigurationException

Default constructor for a plugin of an EventManager called by a service registry.

Parameters:

conf - The configuration as provided from the registry.

eventManager - The event manager this event source is a plugin of.

registry - The registry of this plugin.

Throws:

ConfigurationException - If the configuration is not valid for a PollingFileSource, a ConfigurationException will be thrown.

Method Detail

setConfiguration

public void setConfiguration(org.apache.commons.configuration2.Configuration conf,
                             boolean completed)
                      throws ConfigurationException

Sets the internal fields according to the values of the designated configuration. Note that this method is called from the constructor and therefore this object may not be fully initialised! Sets the configuration by retrieving the session context from it and setting the fields according to the session context. This incorporates overwriting the existing configuration with the values from the activity configuration.
Afterwards parameter references in the attribute values will be replaced with the data context.

Overrides:

setConfiguration in class FileEventSource

Parameters:

conf - The configuration from which to get the configuration values.

completed - Whether the configuration is complete after this setting and therefore the values should be verified.

Throws:

ConfigurationException - If there are problems with the configuration, for instance the configuration does not provide required values, a ConfigurationException may be thrown.
