## Detailed Description

Combines two sets of NameValuePairs.

CombinedNameValuePairs allows you to provide two sets of of NameValuePairs. If a name is not found in the first set, then the second set is searched for the name and value pair. The second set of NameValuePairs often provides default values.

## Constructor & Destructor Documentation

## ◆ CombinedNameValuePairs()

CombinedNameValuePairs::CombinedNameValuePairs | ( | const NameValuePairs & | pairs1,
|  | const NameValuePairs & | pairs2
| ) |  |
| inline

Construct a CombinedNameValuePairs.

Parameters

  pairs1 | reference to the first set of NameValuePairs
  pairs2 | reference to the second set of NameValuePairs

Definition at line 134 of file algparam.h.

## Member Function Documentation

## ◆ GetVoidValue()

bool CombinedNameValuePairs::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.
