## Member Function Documentation

void log4cpp::PropertyConfiguratorImpl::doConfigure | ( | const std::string & | initFileName | ) | throw (ConfigureFailure)`[virtual]`

void log4cpp::PropertyConfiguratorImpl::doConfigure | ( | std::istream & | in | ) | throw (ConfigureFailure)`[virtual]`

void log4cpp::PropertyConfiguratorImpl::configureCategory | ( | const std::string & | categoryname | ) | throw (ConfigureFailure)`[protected]`

configure the given category.

This includes setting its Priority and adding any Appenders.

Todo:
  setting other properties like 'additivity'.

Parameters:

  | categoryname | Name of the category to configure. The name 'rootCategory' refers to the root Category. throw ConfigureFailure

void log4cpp::PropertyConfiguratorImpl::getCategories | ( | std::vector< std::string > & | categories | ) | const`[protected]`

Get the categories contained within the map of properties.

This simply extracts the categories from the map.

Parameters:

  | categories | Reference to a list which is to receive the list of categories.

void log4cpp::PropertyConfiguratorImpl::instantiateAllAppenders | ( |  | ) | throw (ConfigureFailure)`[protected]`

Appender * log4cpp::PropertyConfiguratorImpl::instantiateAppender | ( | const std::string & | name | ) | `[protected]`

Intantiate and configure the appender referred to by the given name.

This method searches the map to find all configuration parameters for the appender, and adds the appender to the given category. This isn't very general in the sense that it will need to be modified for each type of appender and layout. A more general solution would be to define an "options" interface for each appender and layout, so that we can simply call this method with a list of options instead of needing to know what is or is not available. This would also require some generic way of instantiating an object for which we have no knowledge. An "AppenderFactory" could be used which maps the given type to an actual object class registered with the factory (?? is this possible?).

Parameters:

  | name | String containing the name of the type of appender to be instantiated.

void log4cpp::PropertyConfiguratorImpl::setLayout | ( | Appender * | appender,
|  | const std::string & | name |
| ) |  |  | `[protected]`

Method for instantiating and configuring the layouts associated with each appender.

Parameters:

  | appender | Appender to which we are setting this layout.
  | name | Name in the properties of this appender.
