public ObjectParamRule(int paramIndex,
    Object param) 
{
        this(paramIndex, null, param);
}

Construct a "call parameter" rule that will save the given Object as the parameter value.

Parameters:

paramIndex - The zero-relative parameter number

param - the parameter to pass along

 public ObjectParamRule(int paramIndex,
    String attributeName,
    Object param) 
{
        this.paramIndex = paramIndex;
        this.attributeName = attributeName;
        this.param = param;
}

Construct a "call parameter" rule that will save the given Object as the parameter value, provided that the specified attribute exists.

Parameters:

paramIndex - The zero-relative parameter number

attributeName - The name of the attribute to match

param - the parameter to pass along

    String name,
