use of com.google.template.soy.data.LoggingAdvisingAppendable.BufferingAppendable in project closure-templates by google.

the class StreamingPrintDirectivesTest method testStreamingDisablesRuntimeTypeChecks.

/**
 * This test demonstrates a change in behavior when streaming print directives are in use, they
 * can elide some runtime type checking. This is because the compiler explicitly puts in {@code
 * checkcast} instructions whenever calling {@link SoyValueProvider#resolve} (see every caller of
 * {@link ExpressionDetacher#resolveSoyValueProvider(Expression)}). However, when we are able to
 * stream a soy value provider we can't insert a {@code checkcast} instruction because we never
 * actually calculate the full value.
 *
 * <p>We could change SoyValueProvider.renderAndResolve to accept a TypePredicate and we could
 * sometimes enforce it, but for the time being this isn't happening.
