Detailed Description

Signature of a Function.

A Signature describes the faudes types of the positional parameters. Tecnically, a Signature is a vector of Parameters. Each Function may execute serveral variants indicated by setting a particular Signature. A list of valid Signatures is maintained in the coresponding FunctionDefinition.

Core members are

mName: string to identify ths signature
mParameters: vector of Paramters.

The Signature is formally derived from Type to inherit the std token io interface. It is not meant to be registered as a faudes type. The token io format is demonstrated by the following example:

<Signature name="Sum of two integers">
<Parameter name="arg1" ftype="Integer"   access="InOut"/>
<Parameter name="arg2" ftype="Integer"   access="In"/>
<Parameter name="res"  ftype="String"    access="Out" creturn="true"/>
</Signature>

Technical note: the variable parameter feature offered by FunctionDefinition is a purely cosmetic hack implemented in FunctionDefinition:MergeDocumentation. It is superseeded by vector parameters and will hence disappear in a future implementation.
