                                 AccessDeniedException

Returns a list of all resources in the collection

Returns:

A list of resources

Throws:

ResourceException -

AccessDeniedException - If the resource is locked, readonly or authorization failed

getChildren

public IResourceList getChildren(boolean visible,
                                 boolean collections,
                                 boolean links)
                          throws ResourceException,
                                 AccessDeniedException

Returns a filtered list of the resources in this collection.

Parameters:

visible - true: only visible resource (system property "hidden" is false), false: only hidden resources

collections - true: only collections, false: only resources which are not collections

links - true: only links, false: only non-link resources

Returns:

A list of resources

Throws:

ResourceException -

AccessDeniedException - If the resource is locked, readonly or authorization failed

getChildrenCount

public int getChildrenCount(boolean visible,
                            boolean collections,
                            boolean links)
                     throws ResourceException,
                            AccessDeniedException

Returns the number of children in the collection

Parameters:

visible - true: only visible resource (system property "hidden" is false), false: only hidden resources

collections - true: only collections, false: only resources which are not collections

links - true: only links, false: only non-link resources

Returns:

getChildren

public IResourceList getChildren(Selector childrenSelector,
                                 Collator sortBy,
                                 IPropertyNameList propertyPrefill)
                          throws ResourceException,
                                 AccessDeniedException

Returns the children of this collection. The list of children can be filtered and sorted by properties. A child resource is not included in the result if the user in the context does not have read permission for the properties (this is true if at least one parameter is used (not null) which will cause properties to be fetched: Collator, Selector or propertyPrefill).

Parameters:

childrenSelector - Specifies the filter expression

sortBy - Specifies the ordering of the returned list. Children which are collections are grouped together and are placed BEFORE the non-collections.

propertyPrefill - Specifies the names of properties which should be fetched for the children of the collection in addition to those needed for filtering and sorting. This "prefetching" can improve performance of subsequent getProperty() calls on the child resources.

Throws:

ResourceException -

AccessDeniedException - If the resource is locked, readonly or authorization failed

getChildren

public IResourceList getChildren(Selector childrenSelector,
                                 Collator sortBy,
                                 IPropertyNameList propertyPrefill,

                          throws ResourceException,
                                 AccessDeniedException

Returns the children of this collection. The list of children can be filtered by properties and permissions and sorted by properties. A child resource is not included in the result if the user in the context does not have read permission for the properties (this is true if at least one parameter is used (not null) which will cause properties to be fetched: Collator, Selector or propertyPrefill).

Parameters:

childrenSelector - Specifies the filter expression

sortBy - Specifies the ordering of the returned list. Children which are collections are grouped together and are placed BEFORE the non-collections.

propertyPrefill - Specifies the names of properties which should be fetched for the children of the collection in addition to those needed for filtering and sorting. This "prefetching" can improve performance of subsequent getProperty() calls on the child resources.

permissionNames - An array of permission names (permission name constants are defined in IPermission). Resources for which the user in the context does not have one of the secified permissions are removed from the result list.

Throws:

ResourceException -

AccessDeniedException - If the resource is locked, readonly or authorization failed
