Examples of com.opengamma.engine.function.CachingFunctionRepositoryCompiler

com.opengamma.engine.function.CachingFunctionRepositoryCompiler
Implements a {@link FunctionRepositoryCompiler} that caches the results of previous compilations so that a minimal compilation is performed each time.

    final InMemoryFunctionRepository functionRepo = new InMemoryFunctionRepository();
    final FunctionCompilationContext functionCompilationContext = new FunctionCompilationContext();
    functionCompilationContext.setFunctionInitId(123);
    functionCompilationContext.setRawComputationTargetResolver(new DefaultCachingComputationTargetResolver(new DefaultComputationTargetResolver(securitySource, positionSource),
        _cacheManager));
    final CompiledFunctionService cfs = new CompiledFunctionService(functionRepo, new CachingFunctionRepositoryCompiler(), functionCompilationContext);
    cfs.initialize();
    final DefaultFunctionResolver functionResolver = new DefaultFunctionResolver(cfs);
    final ViewCompilationServices vcs = new ViewCompilationServices(new FixedMarketDataAvailabilityProvider(), functionResolver, functionCompilationContext, new PoolExecutor(1, getClass()
        .getSimpleName()),
