Method Detail

onPreQueryPhase

public void onPreQueryPhase(SearchContext searchContext)

Description copied from interface: SearchOperationListener

Executed before the query phase is executed

Specified by:

onPreQueryPhase in interface SearchOperationListener

Parameters:

searchContext - the current search context

onFailedQueryPhase

public void onFailedQueryPhase(SearchContext searchContext)

Description copied from interface: SearchOperationListener

Executed if a query phased failed.

Specified by:

onFailedQueryPhase in interface SearchOperationListener

Parameters:

searchContext - the current search context

onQueryPhase

public void onQueryPhase(SearchContext searchContext,
                         long tookInNanos)

Description copied from interface: SearchOperationListener

Executed after the query phase successfully finished. Note: this is not invoked if the query phase execution failed.

Specified by:

onQueryPhase in interface SearchOperationListener

Parameters:

searchContext - the current search context

tookInNanos - the number of nanoseconds the query execution took

See Also:

SearchOperationListener.onFailedQueryPhase(SearchContext)

onPreFetchPhase

public void onPreFetchPhase(SearchContext searchContext)

Description copied from interface: SearchOperationListener

Executed before the fetch phase is executed

Specified by:

onPreFetchPhase in interface SearchOperationListener

Parameters:

searchContext - the current search context

onFailedFetchPhase

public void onFailedFetchPhase(SearchContext searchContext)

Description copied from interface: SearchOperationListener

Executed if a fetch phased failed.

Specified by:

onFailedFetchPhase in interface SearchOperationListener

Parameters:

searchContext - the current search context

onFetchPhase

public void onFetchPhase(SearchContext searchContext,
                         long tookInNanos)

Description copied from interface: SearchOperationListener

Executed after the fetch phase successfully finished. Note: this is not invoked if the fetch phase execution failed.

Specified by:

onFetchPhase in interface SearchOperationListener

Parameters:

searchContext - the current search context

tookInNanos - the number of nanoseconds the fetch execution took

See Also:

SearchOperationListener.onFailedFetchPhase(SearchContext)

onNewContext

public void onNewContext(SearchContext context)

Description copied from interface: SearchOperationListener

Executed when a new search context was created

Specified by:

onNewContext in interface SearchOperationListener

Parameters:

context - the created context

onFreeContext

public void onFreeContext(SearchContext context)

Description copied from interface: SearchOperationListener

Executed when a previously created search context is freed. This happens either when the search execution finishes, if the execution failed or if the search context as idle for and needs to be cleaned up.

Specified by:

onFreeContext in interface SearchOperationListener

Parameters:

context - the freed search context

onNewScrollContext

public void onNewScrollContext(SearchContext context)

Description copied from interface: SearchOperationListener

Executed when a new scroll search SearchContext was created

Specified by:

onNewScrollContext in interface SearchOperationListener

Parameters:

context - the created search context

onFreeScrollContext

public void onFreeScrollContext(SearchContext context)

Description copied from interface: SearchOperationListener

Executed when a scroll search SearchContext is freed. This happens either when the scroll search execution finishes, if the execution failed or if the search context as idle for and needs to be cleaned up.

Specified by:

onFreeScrollContext in interface SearchOperationListener

Parameters:

context - the freed search context

validateSearchContext

public void validateSearchContext(SearchContext context,
                                  TransportRequest request)

Description copied from interface: SearchOperationListener

Executed prior to using a SearchContext that has been retrieved from the active contexts. If the context is deemed invalid a runtime exception can be thrown, which will prevent the context from being used.

Specified by:

validateSearchContext in interface SearchOperationListener

Parameters:

context - the context retrieved from the active contexts

request - the request that is going to use the search context
