Detailed Description

An object that implements NameValuePairs.

Note

A NameValuePairs object containing an arbitrary number of name value pairs may be constructed by repeatedly using operator() on the object returned by MakeParameters, for example:

    AlgorithmParameters parameters = MakeParameters(name1, value1)(name2, value2)(name3, value3);

Member Function Documentation

GetVoidValue()

bool AlgorithmParameters::GetVoidValue ( const char *  name, const std::type_info &  valueType, void *  pValue  ) const

virtual

Get a named value.

Parameters

name	the name of the object or value to retrieve
valueType	reference to a variable that receives the value
pValue	void pointer to a variable that receives the value

Returns

true if the value was retrieved, false otherwise

GetVoidValue() retrieves the value of name if it exists.

Note

GetVoidValue() is an internal function and should be implemented by derived classes. Users should use one of the other functions instead.
