Method Detail

getKey

public Serializable getKey()

Generate the unique caching key. It includes the class name to ensure uniqueness

Specified by:

getKey in interface org.apache.cocoon.caching.CacheableProcessingComponent

getValidity

public org.apache.excalibur.source.SourceValidity getValidity()

It's not expected that the OpenSearch's configuration to be changed very frecuently, so we assume this component is always valid (the cache should be cleared to update this component)

Specified by:

getValidity in interface org.apache.cocoon.caching.CacheableProcessingComponent
