protected Date getCurrentDateAfterFactoringInDateResolution()

save

public Category save(Category category)

Description copied from interface: CategoryDao

Persist a Category instance to the datastore

save in interface CategoryDao

Parameters:

category - the Category instance

Returns:

the updated state of the passed in Category after being persisted

readCategoryById

public Category readCategoryById(Long categoryId)

Description copied from interface: CategoryDao

Retrieve a Category instance by its primary key

Specified by:

readCategoryById in interface CategoryDao

readCategoryByName

@Deprecated
public Category readCategoryByName(String categoryName)

Deprecated.

Description copied from interface: CategoryDao

the Category having the specified name

readAllParentCategories

public List<Category> readAllParentCategories()

Specified by:

readAllParentCategories in interface CategoryDao

Returns:

a list of all categories that do not have a defaultParentCategory set

readCategoriesByName

public List<Category> readCategoriesByName(String categoryName)

Description copied from interface: CategoryDao

Retrieve a list of Category instances by name.

Specified by:

readCategoriesByName in interface CategoryDao

the Category instances having the specified name

readCategoriesByName

public List<Category> readCategoriesByName(String categoryName,
                                           int limit,
                                           int offset)

Specified by:

readCategoriesByName in interface CategoryDao

readAllCategories

public List<Category> readAllCategories()

Description copied from interface: CategoryDao

Retrieve all categories in the datastore

Specified by:

readAllCategories in interface CategoryDao

Returns:

a list of all the Category instances in the datastore

readAllCategories

public List<Category> readAllCategories(int limit,
                                        int offset)

Description copied from interface: CategoryDao

Retrieve a subset of all categories

Specified by:

readAllCategories in interface CategoryDao

Parameters:

limit - the maximum number of results, defaults to 20

offset - the starting point in the record set, defaults to 0

Returns:

readAllProducts

public List<Product> readAllProducts()

Description copied from interface: CategoryDao

Retrieve all products in the datastore

Specified by:

readAllProducts in interface CategoryDao

Returns:

a list of all Category instances in the datastore, regardless of their category association

readAllProducts

public List<Product> readAllProducts(int limit,
                                     int offset)

Specified by:

readAllProducts in interface CategoryDao

readAllSubCategories

public List<Category> readAllSubCategories(Category category)

Description copied from interface: CategoryDao

Retrieve a list of all child categories of the passed in Category instance

Specified by:

readAllSubCategories in interface CategoryDao

Parameters:

category - the parent category

Returns:

a list of all child categories

readAllSubCategories

public List<Category> readAllSubCategories(Category category,
                                           int limit,
                                           int offset)

Description copied from interface: CategoryDao

Retrieve a list of all child categories of the passed in Category instance

Specified by:

readAllSubCategories in interface CategoryDao

Parameters:

category - the parent category

limit - the maximum number of results to return

offset - the starting point in the record set

Returns:

a list of all child categories

readActiveSubCategoriesByCategory

public List<Category> readActiveSubCategoriesByCategory(Category category)

Description copied from interface: CategoryDao

Retrieve a list of all active child categories of the passed in Category instance. This method bases its search on a current time value. To make the retrieval of values more efficient, the current time is cached for a configurable amount of time. See CategoryDao.getCurrentDateResolution()

Specified by:

readActiveSubCategoriesByCategory in interface CategoryDao

Parameters:

category - the parent category

Returns:

a list of all active child categories

readActiveSubCategoriesByCategory

public List<Category> readActiveSubCategoriesByCategory(Category category,
                                                        int limit,
                                                        int offset)

Description copied from interface: CategoryDao

Retrieve a list of all active child categories of the passed in Category instance. This method bases its search on a current time value. To make the retrieval of values more efficient, the current time is cached for a configurable amount of time. See CategoryDao.getCurrentDateResolution()

Specified by:

readActiveSubCategoriesByCategory in interface CategoryDao

Parameters:

category - the parent category

limit - the maximum number of results to return

offset - the starting point in the record set

Returns:

a list of all active child categories

getCurrentDateResolution

public Long getCurrentDateResolution()

Description copied from interface: CategoryDao

Returns the number of milliseconds that the current date/time will be cached for queries before refreshing. This aids in query caching, otherwise every query that utilized current date would be different and caching would be ineffective.

Specified by:

getCurrentDateResolution in interface CategoryDao

Returns:

the milliseconds to cache the current date/time

setCurrentDateResolution

public void setCurrentDateResolution(Long currentDateResolution)

Description copied from interface: CategoryDao

Sets the number of milliseconds that the current date/time will be cached for queries before refreshing. This aids in query caching, otherwise every query that utilized current date would be different and caching would be ineffective.

Specified by:

setCurrentDateResolution in interface CategoryDao

Parameters:

currentDateResolution - the milliseconds to cache the current date/time

delete

public void delete(Category category)

Description copied from interface: CategoryDao

Removed the passed in Category instance from the datastore

Specified by:

delete in interface CategoryDao

Parameters:

category - the Category instance to remove

create

public Category create()

Description copied from interface: CategoryDao

Create a new Category instance. The system will use the configuration in /BroadleafCommerce/core/BroadleafCommerceFramework/src/main/resources/bl-framework-applicationContext-entity.xml to determine which polymorphic version of Category to instantiate. To make Broadleaf instantiate your extension of Category by default, include an entity configuration bean in your application context xml similar to:

<bean id="blEntityConfiguration" class="org.broadleafcommerce.common.persistence.EntityConfiguration"> <property name="entityContexts"> <list> <value>classpath:myCompany-applicationContext-entity.xml</value> </list> </property> </bean>

Declare the same key for your desired entity in your entity xml that is used in the Broadleaf entity xml, but change the value to the fully qualified classname of your entity extension.

Specified by:

create in interface CategoryDao

Returns:

a Category instance based on the Broadleaf entity configuration.

findCategoryByURI

public Category findCategoryByURI(String uri)

Specified by:

findCategoryByURI in interface CategoryDao
