Examples of com.opengamma.core.position.Position

com.opengamma.core.position.Position
A position in a security held in a portfolio.
A position is fundamentally a quantity of a security. For example, a position might be 50 shares of OpenGamma.
It differs from a trade in that it may represent the combined result from a set of trades. The collection of trades is optional and if present may be incomplete.
This interface is read-only. Implementations may be mutable.


  @Override
  public PortfolioNode createPortfolioNode() {
    final SimplePortfolioNode node = new SimplePortfolioNode(getNameGenerator().createName());
    for (int i = 0; i < getSize(); i++) {
      Position position = getPositionGenerator().createPosition();
      // Note: the code below may be useful if the position generater sometimes fails to produce an entry and the portfolio must
      // contain the required amount. It is not useful if the position generator continually fails and you get an infinite loop.
      //while (position == null) {
      //  position = getPositionGenerator().createPosition();
      //}
