com.opengamma.engine.function.resolver.DefaultFunctionResolver
Default implementation of the function resolver.
The aim of the resolution is to find functions that are capable of satisfying a requirement. In addition, a priority mechanism is used to return functions in priority order from highest to lowest. Resolution actually occurs in the {@code CompiledFunctionResolver}. This class creates a {@code DefaultCompiledFunctionResolver} instance.
This class is not thread-safe.

  public CompiledFunctionService getFunctionCompilationService() {
    return _functionCompilationService;
  }


  public static FunctionResolver createFunctionResolver(final CompiledFunctionService functionCompilationSerice) {
    return new DefaultFunctionResolver(functionCompilationSerice, new FunctionPriority() {
      @Override
      public int getPriority(final CompiledFunctionDefinition function) {
        if (function instanceof CurrencyConversionFunction || function instanceof CurrencySeriesConversionFunction) {
          return Integer.MIN_VALUE;
        }
