AbstractParameterDescriptor

public AbstractParameterDescriptor(int[] sourceLocations,
                                   BindableType<T> expectedType)

Method Detail

getName

public String getName()

Get the Hibernate Type associated with this parameter, if one. May return null.

Returns:

The associated Hibernate Type, may be null.

getExpectedType

public BindableType<T> getExpectedType()

resetExpectedType

allowsMultiValuedBinding

public boolean allowsMultiValuedBinding()

Description copied from interface: QueryParameter

Does this parameter allow multi-valued (collection, array, etc) binding?

This is only valid for HQL/JPQL and (I think) Criteria queries, and is determined based on the context of the parameters declaration.

Specified by:

allowsMultiValuedBinding in interface QueryParameter<T>

Returns:

true indicates that multi-valued binding is allowed for this parameter
