Method Detail

closeIterator

protected void closeIterator(Iterator iter)

Close the given iterator.

Overrides:

closeIterator in class ExtentImpl

Following copied from class: com.solarmetric.kodo.runtime.ExtentImpl

Parameters:

iter - the Iterator to close. This can be an instance of the implementation-dependent Iterator, or it may be a MultiIterator.

getIterator

protected Iterator getIterator(Class candidateClass)

Description copied from class: ExtentImpl

Return an iterator over the extent for the specified candidate class. The candidate class is guaranteed to always be a concrete top-level class.

Overrides:

getIterator in class ExtentImpl

Following copied from class: com.solarmetric.kodo.runtime.ExtentImpl

Parameters:

candidateClass - the class against which the Iterator needs to be obtained. It is important that this parameter be used as opposed to the ExtentImpl.getCandidateClass() method, since the parameter is always guaranteed to be a concrete class, whereas ExtentImpl.getCandidateClass() may return an interface.

getResultList

public ResultList getResultList(Class candidateClass)

Return a ResultList that can be used to access all the data in this extent. This should not cache data; a new ResultList will be requested each time getIterator(java.lang.Class) is invoked. This simply delegates the method to the class' ClassMapping.

Parameters:

candidateClass - the concrete class against which the query will be issued. Note that this is not necessarily the same as the Extent's ExtentImpl.getCandidateClass() method, which might return an interface.
