Method Detail

rebuildIndex

public void rebuildIndex()
                  throws ServiceException,
                         IOException

Description copied from interface: SolrIndexService

Rebuilds the current index.

Specified by:

rebuildIndex in interface SolrIndexService

Throws:

ServiceException

IOException

deleteAllDocuments

protected void deleteAllDocuments()
                           throws ServiceException

Throws:

ServiceException

buildIncrementalIndex

protected void buildIncrementalIndex(int page,
                                     int pageSize)
                              throws ServiceException

Throws:

ServiceException

buildIncrementalIndex

public void buildIncrementalIndex(int page,
                                  int pageSize,
                                  boolean useReindexServer)
                           throws ServiceException

Description copied from interface: SolrIndexService

The internal method for building indexes. This is exposed via this interface in case someone would like to more granularly control the indexing strategy.

Specified by:

buildIncrementalIndex in interface SolrIndexService

useReindexServer - - if set to false will index directly on the primary server

Throws:

ServiceException

SolrIndexService.restoreState(Object[])

readAllActiveProducts

protected List<Product> readAllActiveProducts()

This method to read all active products will be slow if you have a large catalog. In this case, you will want to read the products in a different manner. For example, if you know the fields that will be indexed, you can configure a DAO object to only load those fields. You could also use a JDBC based DAO for even faster access. This default implementation is only suitable for small catalogs.

Returns:

the list of all active products to be used by the index building task

readAllActiveProducts

protected List<Product> readAllActiveProducts(int page,
                                              int pageSize)

This method to read active products utilizes paging to improve performance over readAllActiveProducts(). While not optimal, this will reduce the memory required to load large catalogs. It could still be improved for specific implementations by only loading fields that will be indexed or by accessing the database via direct JDBC (instead of Hibernate).

Returns:

the list of all active products to be used by the index building task

Since:

2.2.0

getAllLocales

public List<Locale> getAllLocales()

Specified by:

getAllLocales in interface SolrIndexService

Returns:

a list of all possible locale prefixes to consider

buildDocument

public org.apache.solr.common.SolrInputDocument buildDocument(Product product,
                                                              List<Field> fields,
                                                              List<Locale> locales)

Description copied from interface: SolrIndexService

Given a product, fields that relate to that product, and a list of locales and pricelists, builds a SolrInputDocument to be added to the Solr index.

Specified by:

buildDocument in interface SolrIndexService

Returns:

the document

attachBasicDocumentFields

protected void attachBasicDocumentFields(Product product,
                                         org.apache.solr.common.SolrInputDocument document)

Adds the ID, category, and explicitCategory fields for the product to the document

Parameters:

product -

document -

getPropertyValues

protected Map<String,Object> getPropertyValues(Product product,
                                               Field field,
                                               FieldType fieldType,
                                               List<Locale> locales)
                                        throws IllegalAccessException,
                                               InvocationTargetException,
                                               NoSuchMethodException

Returns a map of prefix to value for the requested attributes. For example, if the requested field corresponds to a Sku's description and the locales list has the en_US locale and the es_ES locale, the resulting map could be { "en_US" : "A description", "es_ES" : "Una descripcion" }

Parameters:

product -

field -

isPriceField -

prefix -

Returns:

the value of the property

Throws:

IllegalAccessException

InvocationTargetException

NoSuchMethodException

convertToMappedProperty

protected String convertToMappedProperty(String propertyName,
                                         String listPropertyName,
                                         String mapPropertyName)

Converts a propertyName to one that is able to reference inside a map. For example, consider the property in Product that references a List, "productAttributes". Also consider the utility method in Product called "mappedProductAttributes", which returns a map of the ProductAttributes keyed by the name property in the ProductAttribute. Given the parameters "productAttributes.heatRange", "productAttributes", "mappedProductAttributes" (which would represent a property called "productAttributes.heatRange" that references a specific ProductAttribute inside of a product whose "name" property is equal to "heatRange", this method will convert this property to mappedProductAttributes(heatRange).value, which is then usable by the standard beanutils PropertyUtils class to get the value.

Parameters:

propertyName -

listPropertyName -

mapPropertyName -

Returns:

the converted property name
