ParameterValueProvider

Description:
Gets the value of a parameter from any element passed to GetStringValue, GetDoubleValue, GetIntegerValue, or GetElementIdValue.

Remarks:

For any parameter, only one of isStringValueSupported, isDoubleValueSupported, isIntegerValueSupported, isElementIdValueSupported will return true. No attempt to convert between types is made. For example, calling GetStringValue, passing the identifier of a numeric-typed parameter will give an empty string. No exception will be thrown, and ParameterValueProvider will not attempt to convert the numeric value to a string.

If an element doesn't have the requested parameter or the element's parameter doesn't have a valid value, ParameterValueProvider will attempt to get the parameter value from the element's type - see GetTypeId().
