Method Detail

readCategoryById

@Nonnull
Category readCategoryById(@Nonnull
                                  Long categoryId)

Retrieve a Category instance by its primary key

Parameters:

categoryId - the primary key of the Category

Returns:

the Category at the specified primary key

readCategoryByName

@Nonnull
@Deprecated
Category readCategoryByName(@Nonnull
                                               String categoryName)

Deprecated.

Retrieve a Category instance by its name. Broadleaf allows more than one category to have the same name. Calling this method could produce an exception in such situations. Use readCategoriesByName(String) instead.

Parameters:

categoryName - the name of the category

Returns:

the Category having the specified name

readAllParentCategories

List<Category> readAllParentCategories()

Returns:

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

readCategoriesByName

@Nonnull
List<Category> readCategoriesByName(@Nonnull
                                            String categoryName)

Retrieve a list of Category instances by name.

Parameters:

categoryName - the name to search by

Returns:

the Category instances having the specified name

readCategoriesByName

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

readAllCategories

@Nonnull
List<Category> readAllCategories()

Retrieve a subset of all categories

Parameters:

limit - the maximum number of results, defaults to 20

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

Returns:

readAllProducts

delete

void delete(@Nonnull
            Category category)

Removed the passed in Category instance from the datastore

Parameters:

category - the Category instance to remove

create

@Nonnull
Category create()

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.

Returns:

a Category instance based on the Broadleaf entity configuration.

readActiveSubCategoriesByCategory

@Nonnull
List<Category> readActiveSubCategoriesByCategory(Category category)

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 #getCurrentDateResolution()

Parameters:

category - the parent category

Returns:

a list of all active child categories

readActiveSubCategoriesByCategory

@Nonnull
List<Category> readActiveSubCategoriesByCategory(@Nonnull
                                                         Category category,
                                                         @Nonnull
                                                         int limit,

                                                         int offset)

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 #getCurrentDateResolution()

Parameters:

category - the parent category
