    Sets whether the type of user-supplied bind parameter value and the type of target persistent property they bind to are checked with strong or weak constraint.

    Parameters:

    Returns:
    
    the booelan state. False by default, i.e. the type of a bind parameter value is checked strongly against the target property type.
