Direct Known Subclasses:

CustomCatalogTools

public class CatalogTools
extends GenericService
implements MessageTyper

This class represents a series of helper methods and properties that are used in the management of accessing the product catalog.

One can configure this component to define a mapping from a key to a set of alternate catalogs. This is particularly useful for internationalization.
For example: CatalogTools.properties

 $class=atg.commerce.catalog.CatalogTools

 catalog=ProductCatalog

 baseProductItemType=product
 baseCategoryItemType=category
 baseSKUItemType=sku
 baseMediaItemType=media

 productItemTypes=product
 categoryItemTypes=category
 SKUItemTypes=sku

 alternateCatalogs=\
      en_US=/atg/commerce/catalog/ProductCatalog
      fr_FR=/atg/commerce/catalog/FrenchProductCatalog
      ja_JP=/atg/commerce/catalog/JapaneseProductCatalog
      de_DE=/atg/commerce/catalog/GermanProductCatalog

 useDefaultCatalog=true
 

The behavior of the findProduct(), findCategory(), and findSku() methods can be modified with use of the useDefaultCatalog property. If useDefaultCatalog is false and an alternate catalog repository cannot be found that matches the pCatalogKey parameter, then no repository is searched and null will be returned.

Validates if the SKU/Product is marked with fractional quantities allowed.

A product being marked with fractional quantities allowed will override any SKU setting. If a product is marked as a fractional quantities allowed all SKUs associated with this product will become fractional quantities allowed even if the individual SKUs have been marked as non-fractional.

A fractional quantity SKU in a non-fractional product is a fractional quantity. If a SKU has been marked as a fractional quantity allowed this SKU will be treated as a fractional quantity and can ignore the product flag.

Parameters:

pProductId - the product Id. This is mandatory

pSkuId - the sku Id

Returns:

True if fractional quantities are allowed.False if not and If unable to determine false is returned

Throws:

RepositoryException - if there was an error during repository lookup

Returns the unit of measure.

If a SKU is associated with a unit of measure value, the SKU uses its own unit of measure value and configuration otherwise it uses that of the product.

Parameters:

pProductId - the product Id

pSkuId - the sku Id

Returns:

String. The unit of measure to use

Throws:

RepositoryException - if there was an error during repository lookup

Verify that a specified sku ID is an ID of a child sku of the specified product.

Parameters:

pProduct - The product

pSkuId - The sku id to test

Returns:

Return true if the specified SKU ID is represented by one of the product's skus. Return false if the sku is not one of the child skus, or its status cannnot be determined either because we cannot locate the child skus property of the product, or we cannot examine the resulting object type to see if it contains the target sku.

                                  java.lang.Object pSku)

Verify that a specified sku is actually a child sku of the specified product. Many of the parameters passed in to this method are not required by the default implementation, but are provided so that subclasses can implement more complex forms of checking.

Parameters:

pCatalogId - The catalog id of the particular catalog from which a commerce item is being created. May be null if custom catalogs are not in use.

pProductId - The product id of the product being examined. May be null if no product id was supplied in the call to createCommerceItem.

pProduct - The product object corresponding to pProductId, which may be null if pProductId is null.

pSkuId - The sku id of the sku being examined. This value should never be null.

pSku - The sku object corresponding to pSkuId

Returns:

Return true if the specified sku is one of the product's child skus, or of the product is null. Return false if the sku is not one of the child skus, or its status cannnot be determined either because we cannot locate the child skus property of the product, or we cannot examine the resulting object type to see if it contains the target sku.
