Inheritance diagram for NameValuePairs:
To obtain an object that implements NameValuePairs for the purpose of parameter passing, use the MakeParameters() function.
To get a value from NameValuePairs, you need to know the name and the type of the value. Call GetValueNames() on a NameValuePairs object to obtain a list of value names that it supports. Then look at the Name namespace documentation to see what the type of each value is, or alternatively, call GetIntValue() with the value name, and if the type is not int, a ValueTypeMismatch exception will be thrown and you can get the actual type from the exception object.

bool NameValuePairs::GetIntValue | ( | const char * | name, | |

) | const [inline] |
get a named value with type int
used to ensure we don't accidentally try to get an unsigned int or some other type when we mean int (which is the most common case)
