Method Detail

addItemDescriptors

protected static void addItemDescriptors(RepositoryItemDescriptor pDescriptor,
                                         java.util.Collection pItemDescriptors)
                                  throws RepositoryException

This method determines if the RepositoryItemDescriptor has any subtypes (if its a RepositoryItemDescriptorContainer) and then adds all subtype item-descriptors and the item-descriptor passed to this method to the collection of item-descriptors passed to this method.

Parameters:

pDescriptor - the item-descriptor that should be checked for subtypes and then added to the itemDescriptors collection

pItemDescriptors - a collection of item-descriptors

Throws:

RepositoryException

getAllSubtypeItemDescriptors

public static java.util.Collection<RepositoryItemDescriptor> getAllSubtypeItemDescriptors(atg.repository.RepositoryItemDescriptorContainer pItemDescriptor)
                                                                                   throws RepositoryException

Returns a collection of item-descriptors that are subtypes of the item-descriptor passed to this method. For example, if there is an address item that has two subtypes; home and business this method will return the home and business item-descriptors.

Additionally, if any of those item-descriptors themselves have subtype descriptors, those will be returned in the Collection as well. For example, if the home address subtype had a subtype, this would appear in the Collection as well.

Parameters:

pItemDescriptor - item-descriptor to discover subtypes for. If there are no subtypes associated with the item-descriptor passed, then null will be returned

Returns:

collection subtype item-descriptors

Throws:

RepositoryException

cloneItem

public static MutableRepositoryItem cloneItem(RepositoryItem pSource,
                                              boolean pDeepCopy,
                                              java.util.Map pPropExceptions,
                                              java.util.Map pExcludedProperties,
                                              MutableRepository pDestRepository,
                                              java.lang.String pId)
                                       throws RepositoryException,
                                              DuplicateIdException

Create a copy of a RepositoryItem in a repository without adding the item. Can specify a default copy mode of deep or shallow as well as a list of property name exceptions to this mode.

Parameters:

pSource - Item to copy.

pDeepCopy - The mode of the copy. If true, default to a deep copy of the item and its properties. Otherwise, default to a shallow copy, only getting references of child RepositoryItems. Note that shallow coping will only work if the source and destination and repositories are the same.

pPropExceptions - Hierarchical map of property name exceptions to the above mode. Keys are property names while values are null or another Map if the property is an item. For example, if you clone a product using pDeepCopy=true, you could add the key "parentCategory" with a null value into pPropExceptions to cause a shallow copy of the product.parentCategory. Alternatively, you could add the key "parentCategory" but set the value to another map of exceptions that included the key/value pair "keywords"/null to do a deep copy of product.parentCategory but a shallow copy of the product.parentCategory.keywords. Optional.

pExcludedProperties - Properties to exclude from clone. Keys are item-type names and the values are collections of property names to exclude. Optional.

pDestRepository - Repository to copy the item to. If source and destination repositories are the same, properties that are items will be cloned to the repository of the source item-property. Optional - If null, copy to source repository.

pId - Id to use in copy of item. Optional - if null, a unique Id will automatically be generated.

Throws:

RepositoryException - Thrown if the item could not be created.

DuplicateIdException - Thrown if the specified Id is already in use.

                                              MutableRepository pDestRepository,
                                              java.lang.String pId)
                                       throws RepositoryException,
                                              DuplicateIdException

Create a copy of a RepositoryItem in a repository without adding the item. Can specify a default copy mode of deep or shallow as well as a list of property name exceptions to this mode.

Parameters:

pSource - Item to copy.

pDeepCopy - The mode of the copy. If true, default to a deep copy of the item and its properties. Otherwise, default to a shallow copy, only getting references of child RepositoryItems. Note that shallow coping will only work if the source and destination and repositories are the same.

pPropExceptions - Hierarchical map of property name exceptions to the above mode. Keys are property names while values are null or another Map if the property is an item. For example, if you clone a product using pDeepCopy=true, you could add the key "parentCategory" with a null value into pPropExceptions to cause a shallow copy of the product.parentCategory. Alternatively, you could add the key "parentCategory" but set the value to another map of exceptions that included the key/value pair "keywords"/null to do a deep copy of product.parentCategory but a shallow copy of the product.parentCategory.keywords. Optional.

pDestRepository - Repository to copy the item to. If source and destination repositories are the same, properties that are items will be cloned to the repository of the source item-property. Optional - If null, copy to source repository.

pId - Id to use in copy of item. Optional - if null, a unique Id will automatically be generated.

Throws:

RepositoryException - Thrown if the item could not be created.

DuplicateIdException - Thrown if the specified Id is already in use.

anyReferencesToItem

public static boolean anyReferencesToItem(RepositoryItem pItem)
                                   throws RepositoryException

Query whether any cross-references to a repository item exist within the repository that contains that item. This method can only detect references through queryable properties.

Calling this method will generate multiple repository queries per call, one for each property descriptor that might refer to pItem. For example, if pItem's type is "contact-info", one query will be performed for each property descriptor whose type is either contact-info or any multi-valued type that might contain a list of items of type contact-info. (The queries will each fetch at most one item from the repository, so the effect on the repository's cache should be minimal.)

Parameters:

pItem - Any repository item.

Returns:

true if any other item in pItem's repository refers to pItem

Throws:

RepositoryException

removeReferencesToItem

                                   throws RepositoryException

Removes any references to a given from others items in its repository. This method can only remove references in queryable properties.

Calling this method will generate multiple repository queries per call, one for each property descriptor that might refer to pItem. For example, if pItem's type is "contact-info", one query will be performed for each property descriptor whose type is either contact-info or any multi-valued type that might contain a list of items of type contact-info.

Parameters:

pItem - Any repository item.

Throws:
