select
public List<T> select(ObjectContext context)
Deprecated.Description copied from interface:Select
Selects objects using provided context.Essentially the inversion of "ObjectContext.select(Select)".
-
selectOne
public T selectOne(ObjectContext context)
Deprecated.Description copied from interface:Select
Selects a single object using provided context. The query is expected to match zero or one object. It returns null if no objects were matched. If query matched more than one object,CayenneRuntimeException
is thrown.Essentially the inversion of "ObjectContext.selectOne(Select)".
-
selectFirst
public T selectFirst(ObjectContext context)
Deprecated.Description copied from interface:Select
Selects a single object using provided context. The query itself can match any number of objects, but will return only the first one. It returns null if no objects were matched.If it matched more than one object, the first object from the list is returned. This makes 'selectFirst' different from
Select.selectOne(ObjectContext)
, which would throw in this situation. 'selectFirst' is useful e.g. when the query is ordered and we only want to see the first object (e.g. "most recent news article"), etc.Selecting the first object via "Select.selectFirst(ObjectContext)" is more comprehensible than selecting via "ObjectContext.selectFirst(Select)", because implementations of "Select" set fetch size limit to one.
- Specified by:
selectFirst
in interfaceSelect<T>
-
iterate
public void iterate(ObjectContext context, ResultIteratorCallback<T> callback)
Deprecated.Description copied from interface:Select
Creates a ResultIterator based on the provided context and passes it to a callback for processing. The caller does not need to worry about closing the iterator. This method takes care of it.Essentially the inversion of "ObjectContext.iterate(Select, ResultIteratorCallback)".
-
iterator
public ResultIterator<T> iterator(ObjectContext context)
Deprecated.Description copied from interface:Select
Creates a ResultIterator based on the provided context. It is usually backed by an open result set and is useful for processing of large data sets, preserving a constant memory footprint. The caller must wrap iteration in try/finally (or try-with-resources for Java 1.7 and higher) and close the ResultIterator explicitly. Or useSelect.iterate(ObjectContext, ResultIteratorCallback)
as an alternative.Essentially the inversion of "ObjectContext.iterator(Select)".
-
batchIterator
public ResultBatchIterator<T> batchIterator(ObjectContext context, int size)
Deprecated.Description copied from interface:Select
Creates a ResultBatchIterator based on the provided context and batch size. It is usually backed by an open result set and is useful for processing of large data sets, preserving a constant memory footprint. The caller must wrap iteration in try/finally (or try-with-resources for Java 1.7 and higher) and close the ResultBatchIterator explicitly.- Specified by:

pageSize
