List of allocateIds() Examples

Examples of allocateIds()

com.google.appengine.api.datastore.DatastoreService.allocateIds()
IDs are allocated within a namespace defined by a parent key and a kind. This method allocates a contiguous range of unique IDs of size {@code num}within the namespace defined by a null parent key (root entities) and the given kind. IDs allocated in this manner may be provided manually to newly created entities. They will not be used by the datastore's automatic ID allocator for root entities of the same kind. @param kind The kind for which the root entity IDs should be allocated. @param num The number of IDs to allocate. @return A {@code KeyRange} of size {@code num}. @throws IllegalArgumentException If {@code num} is less than 1 or if{@code num} is greater than 1 billion. @throws DatastoreFailureException If a datastore error occurs.
