com.opengamma.engine.function.MarketDataSourcingFunction

Special case of function implementation that is never executed by the graph executor but is used to source market data. It will not be considered directly during graph construction; the singleton instance is associated with DependencyNode objects to act as a marker on the node.

This should never be present in a function repository as it should never be selected for execution.

  private DependencyNode createNode(final String name, final Set<DependencyNode> inputNodes) {
    final ComputationTarget target = getTarget(name);
    final DependencyNode node = new DependencyNode(target);
    final ValueSpecification output;
    if (inputNodes.isEmpty()) {
      final MarketDataSourcingFunction msdf = MarketDataSourcingFunction.INSTANCE;
      output = new ValueSpecification(name, target.toSpecification(), ValueProperties.with(ValuePropertyNames.FUNCTION, msdf.getUniqueId()).get());
      node.setFunction(new ParameterizedFunction(msdf, msdf.getDefaultParameters()));
    } else {
      final MockFunction mock = new MockFunction(target);
      output = new ValueSpecification(name, target.toSpecification(), ValueProperties.with(ValuePropertyNames.FUNCTION, mock.getUniqueId()).get());
      node.setFunction(mock);
      mock.addResult(new ComputedValue(output, null));
