Port annotation

When a function is annotated with Amino::Node, its parameter list will automatically be interpreted by cpp2json as the node's ports.

Input parameters and input/output parameters must come before the output parameters in the parameter list. Input parameters are passed by value or as const references. Output parameters and input/output parameters are passed as non-const references.

With the exception of input/output parameters, parameters declared this way are interpreted as their respective port types by cpp2json and do not require special annotation.

There are three situations when you should annotate a parameter or a port:

• Input/output parameters must be annotated with Amino::InOut. See Annotating input/output parameters for details.
• Output ports that pass along the function's return value should be annotated with the Amino::Node annotation's outName token. See Annotating return values for details.
• Associative input parameters must be annotated with Amino::IsAssociative. See Associative node annotation for details.
