| MedorFactory | | abstract public class MedorFactory extends JormFactory (Code) | | This class does the initialisation of Medor and permits to access to the
query. The optimisation of the query tree is done during the first time that
it is used.

| public TupleCollection | evaluate(Object conn, int methodIndex, ParameterOperand[] parameters)
It evaluate an optimized medor request according to the specified
parameters To evalute the medor request the query evaluator is used. | | public synchronized QueryEvaluator | getOptimizedRequest(MethodCmp2Desc methodDesc)
It retrieves a medor request which is evaluable and optimized. | | public void | init(EntityDesc ed, JContainer c, String mapperName)

| evaluate | | public TupleCollection evaluate(Object conn, int methodIndex, ParameterOperand[] parameters) throws MedorException(Code) | | It evaluate an optimized medor request according to the specified
parameters To evalute the medor request the query evaluator is used.
Parameters:
conn - is the connection handle
Parameters:
methodIndex - is method index which permits to find a medor request.
Parameters:
parameters - is the parameters (key=parameter name / value=parametervalue) TupleCollection is the result of the request |
| getOptimizedRequest | | public synchronized QueryEvaluator getOptimizedRequest(MethodCmp2Desc methodDesc) throws MedorException(Code) | | It retrieves a medor request which is evaluable and optimized. The method
index is translate into a request index, then the found request is
optimized if it is not already.
Parameters:
methodDesc - is the MethodCmp2Desc of the finder or select method. the QueryTree optimized which is associated to the method index |
