com.google.template.soy.tofu.restricted.SoyTofuPrintDirective

Interface for a Soy print directive implemented for the Tofu backend (a.k.a. Java Object backend).

Important: This may only be used in implementing print directive plugins.

Consider also implementing {@link com.google.template.soy.shared.restricted.SoyJavaRuntimePrintDirective}. The {@code apply()} method in {@code SoyJavaRuntimePrintDirective} should be exactly the same as the{@code applyForTofu()} method of this interface, but can be used outside of the Tofu backend byoptimization passes. The easiest way to implement both interfaces at once is to subclass {@link SoyAbstractTofuPrintDirective}. @see SoyAbstractTofuPrintDirective @see com.google.template.soy.shared.restricted.SoyJavaRuntimePrintDirective @author Kai Huang


  @Override protected SoyData applyDirective(
      String directiveName, SoyData value, List<SoyData> args, SoyNode node) {


    // Get directive.
    SoyTofuPrintDirective directive = soyTofuDirectivesMap.get(directiveName);
    if (directive == null) {
      throw new RenderException(
          "Failed to find Soy print directive with name '" + directiveName + "'" +
          " (tag " + node.toSourceString() + ")");
    }


    // TODO: Add a pass to check num args at compile time.
    if (! directive.getValidArgsSizes().contains(args.size())) {
      throw new RenderException(
          "Print directive '" + directiveName + "' used with the wrong number of" +
          " arguments (tag " + node.toSourceString() + ").");
    }


    return directive.applyForTofu(value, args);
  }
