MnaParamTree

Namespace: MNALIB  ·  Library: MNA Library

#include <mna/mna_param_tree.h>

class MNALIB::MnaParamTree

Hierarchical parameter store for the MNA graph.

Each parameter has a path ("nodeId/attrKey") and an optional binding — a formula that recomputes the value whenever a trigger condition is met.

Path-keyed parameter store with formula-driven dynamic bindings.

Public Methods​

MnaParamTree()​

setParam(path, value)​

param(path)​

evaluate(results)​

Evaluate all bindings whose trigger condition is met.

Parameters:

  • results : const QMap< QString, QVariant > & Map of nodeId::portName → data (from execution context).

Returns:

  • QStringList — Paths whose values changed.

evaluateExpression(expr, results)​

Evaluate a single expression in the current context.

Parameters:

  • expr : const QString & Expression string.

  • results : const QMap< QString, QVariant > & Map of nodeId::portName → data (from execution context).

Returns:

  • QVariant — Computed value.
