com.google.template.soy.tofu.restricted.SoyTofuFunction

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

Important: This may only be used in implementing function plugins.

Consider also implementing {@link com.google.template.soy.shared.restricted.SoyJavaRuntimeFunction}. The {@code compute()}method in {@code SoyJavaRuntimeFunction} should be exactly the same as the{@code computeForTofu()} 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 SoyAbstractTofuFunction}. @see SoyAbstractTofuFunction @see com.google.template.soy.shared.restricted.SoyJavaRuntimeFunction @author Kai Huang




  @Override protected SoyData computeFunction(
      String fnName, List<SoyData> args, FunctionNode fnNode) {


    SoyTofuFunction fn = soyTofuFunctionsMap.get(fnName);
    if (fn == null) {
      throw new RenderException(
          "Failed to find Soy function with name '" + fnName + "'" +
          " (function call \"" + fnNode.toSourceString() + "\").");
    }


    // Arity has already been checked by CheckFunctionCallsVisitor.


    try {
      return fn.computeForTofu(args);
    } catch (Exception e) {
      throw new RenderException(
          "Error while computing function \"" + fnNode.toSourceString() + "\": " + e.getMessage());
