Detailed Description

Extend the Parametrizable interface with support for parameter aliases.

Parameter aliases allows several parameter to be constrained together, and for instance, be jointly estimated. The alias relationship is not symmetric:

aliasParameters("a","b");

results in the value of "b" being updated when a is modified, but a will not be updated upon modification of "a". "b" will also be removed of the list of "independent" parameters. Furthermore, a parameter can only be aliased with another one:

aliasParameters("a","b");
aliasParameters("c","b"); //ERROR, throws an exception.

However, several parameters can be aliased to the same one:

aliasParameters("a","b");
aliasParameters("a","c");

In this case, modifying "a" will automatically update the values of "b" and "c", and "b" and "c" are removed from the list of indepedent parameters. Finally, parameters can be chained:

aliasParameters("a","b");
aliasParameters("b","c");

is equivallent to the previous example.

aliasParameters() [1/2]

virtual void bpp::ParameterAliasable::aliasParameters ( const std::string &  p1, const std::string &  p2  )

pure virtual

Set two parameters as 'aliased'.

The values of the two parameters will be synchronized, so that setting the value of one parameter will automatically set the value of the other one accordingly.

Parameters

p1	Original parameter.
p2	Aliased parameter.

Exceptions

ParameterNotFoundException	if p1 or p2 do not correspond to existing parameters.
Exception	when trying to perform non-valid association.

Implemented in bpp::AbstractParameterAliasable.

Referenced by ~ParameterAliasable().

aliasParameters() [2/2]

virtual void bpp::ParameterAliasable::aliasParameters ( std::map< std::string, std::string > &  unparsedParams, bool  verbose  )

pure virtual

alias the parameters following the links described in a map, and update the object accordingly. Cycles in aliasing are detected and forbidden.

Parameters

unparsedParams	the map of the links : <A,B> matches for A->B aliasing.
verbose	verbosity

Implemented in bpp::AbstractParameterAliasable.
