public class DynamicFilterParameterSpecification
extends java.lang.Object
A specialized ParameterSpecification impl for dealing with a dynamic filter
parameters.
Note: this class is currently not used. The ideal way to deal with dynamic filter
parameters for HQL would be to track them just as we do with other parameters
in the translator. However, the problem with that is that we currently do not
know the filters which actually apply to the query; we know the active/enabled ones,
but not the ones that actually "make it into" the resulting query.
int | bind(PreparedStatement statement, QueryParameters qp, SessionImplementor session, int position) - Bind the appropriate value into the given statement at the specified position.
|
Type | getExpectedType() - Get the type which we are expeting for a bind into this parameter based
on translated contextual information.
|
String | renderDisplayInfo() - Render this parameter into displayable info (for logging, etc).
|
void | setExpectedType(Type expectedType) - Injects the expected type.
