Interface IndexerContextFactory<T extends IndexerContext>

All Known Implementing Classes:

DefaultIndexerContextFactory

public interface IndexerContextFactory<T extends IndexerContext>

Implementations of this interface are responsible for creating and destroying instances of IndexerContext.

Code creating/destroying contexts should normally use the following pattern:

 try
 {
        final IndexerContext context = indexerContextFactory.createContext(externalIndexOperation, indexerOperation,
                        facetSearchConfig, indexedType, indexedProperties, pks);

        // call additional setters on the context object

        indexerContextFactory.prepareContext();

        // call the setter for the PKs.

        indexerContextFactory.initializeContext();

        // put your logic here

        indexerContextFactory.destroyContext();
 }
 catch (final IndexerException | ... | RuntimeException e)
 {
        indexerContextFactory.destroyContext(e);
        throw e;
 }
 

Method Summary

Modifier and Type	Method and Description
T	createContext(long indexOperationId, IndexOperation indexOperation, boolean externalIndexOperation, FacetSearchConfig facetSearchConfig, IndexedType indexedType, java.util.Collection<IndexedProperty> indexedProperties) Creates a new indexer context and sets it as the current one.
void	destroyContext() Destroys the current context.
void	destroyContext(java.lang.Exception exception) Destroys the current context because an exception occurred.
T	getContext() Returns the current context.
void	initializeContext() Initializes the current context and executes the before index listeners (see IndexerListener.beforeIndex(IndexerContext)).
void	prepareContext() Prepares the context and executes the after prepare context listeners (see ExtendedIndexerListener.afterPrepareContext(IndexerContext)).

Method Detail

createContext

T createContext(long indexOperationId,
                IndexOperation indexOperation,
                boolean externalIndexOperation,
                FacetSearchConfig facetSearchConfig,
                IndexedType indexedType,
                java.util.Collection<IndexedProperty> indexedProperties)

Creates a new indexer context and sets it as the current one.

Parameters:

indexOperationId - - the index operation id

indexOperation - - the index operation

externalIndexOperation - - indicates if the index operation is external

facetSearchConfig - - the facet search configuration

indexedType - - the indexed type

indexedProperties - - the properties to index

Returns:

the new context

prepareContext

void prepareContext()
             throws IndexerException

Prepares the context and executes the after prepare context listeners (see ExtendedIndexerListener.afterPrepareContext(IndexerContext)).

Throws:

IndexerException - if an error occurs during the listeners execution

initializeContext

void initializeContext()
                throws IndexerException

Initializes the current context and executes the before index listeners (see IndexerListener.beforeIndex(IndexerContext)).

Throws:

IndexerException - if an error occurs during the listeners execution

getContext

T getContext()

Returns the current context.

Returns:

the current context

destroyContext

void destroyContext()
             throws IndexerException

Destroys the current context. Before destroying an active context it executes the after index listeners (see IndexerListener.afterIndex(IndexerContext)).

Throws:

IndexerException - if an error occurs during the listeners execution

destroyContext

void destroyContext(java.lang.Exception exception)

Destroys the current context because an exception occurred. Before destroying an active context it executes the after index error listeners (see IndexerListener.afterIndexError(IndexerContext)).
