All Implemented Interfaces:

ConfigurationAware, MustacheListener

public class SimpleStatsCollector
extends AbstractStatsCollector

A simple MustacheListener collecting template rendering statistics. Note that the template is identified with the name/id - so data will not be correct if there's more than one templates with the same name (which is possible if using MustacheEngine.compileMustache(String, String)). This listener is not able to detect rendering errors.

Method Detail

init

public void init()

Description copied from class: AbstractConfigurationAware

Can be overridden so that there's no need to call super.init(Configuration).

Overrides:

init in class AbstractConfigurationAware

Specified by:

renderingStarted in interface MustacheListener

Overrides:

renderingStarted in class AbstractMustacheListener

clearData

public void clearData()
