org.trimou.engine.listener

Class EnhancedStatsCollector

java.lang.Object

org.trimou.engine.config.AbstractConfigurationAware

org.trimou.engine.listener.AbstractMustacheListener

org.trimou.engine.listener.AbstractStatsCollector

org.trimou.engine.listener.EnhancedStatsCollector

All Implemented Interfaces:

ConfigurationAware, MustacheListener

public class EnhancedStatsCollector
extends AbstractStatsCollector

Unlike SimpleStatsCollector this listener is able to detect rendering errors. Also Identified.getGeneratedId() is used to map statistics to a template. On the other hand it's more resource-intensive.

Method Detail

renderingStarted

public void renderingStarted(MustacheRenderingEvent event)

Description copied from interface: MustacheListener

Rendering of a Mustache is about to start. Always use ReleaseCallbackContainer.registerReleaseCallback(ReleaseCallback) to release all the necessary resources.

Specified by:

renderingStarted in interface MustacheListener

Overrides:

renderingStarted in class AbstractMustacheListener

renderingFinished

public void renderingFinished(MustacheRenderingEvent event)

Description copied from interface: MustacheListener

Rendering of a Mustache is about to finish. Always use ReleaseCallbackContainer.registerReleaseCallback(ReleaseCallback) to release all the necessary resources.

Specified by:

renderingFinished in interface MustacheListener

Overrides:

renderingFinished in class AbstractMustacheListener

init

protected 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

getStats

public AbstractStatsCollector.Stats getStats(Mustache mustache)

Parameters:

mustache -

Returns:

the statistics for the given template

getStats

public Set<AbstractStatsCollector.Stats> getStats()

Returns:

the statistics

getRawData

public Collection<EnhancedStatsCollector.ExecutionData> getRawData(Mustache mustache)

Parameters:

mustache -

Returns:

the raw data for the given template

clearData

public void clearData()

Drop all the collected data.
