Example 1 with TypeConverter

use of org.sosy_lab.common.configuration.converters.TypeConverter in project java-common-lib by sosy-lab.

the class Configuration method convertDefaultValue.

@Nullable
private <T> Object convertDefaultValue(String optionName, @Nullable T defaultValue, TypeToken<T> type, @Nullable Annotation secondaryOption) throws InvalidConfigurationException {
    @Var TypeToken<?> innerType;
    if (type.isArray()) {

    } else if (COLLECTIONS.containsKey(type.getRawType())) {
        innerType = Classes.getSingleTypeArgument(type);
    } else {
        innerType = type;
    }
    innerType = innerType.wrap();
    checkApplicability(secondaryOption, innerType);
    if (type.equals(innerType)) {
        // If its not a collection, we try to pass the default value to the
        // type converter if there is any.
        // TODO: Also pass default values inside a collection.
        TypeConverter converter = getConverter(type, secondaryOption);
        return converter.convertDefaultValue(optionName, defaultValue, type, secondaryOption);
    }
    return defaultValue;
}

Example 2 with TypeConverter

use of org.sosy_lab.common.configuration.converters.TypeConverter in project java-common-lib by sosy-lab.

the class Configuration method convertSingleValue.

/**
 * This function takes a value (String) and a type and returns an Object of this type with the
 * value as content.
 *
 * <p>The type may not be an array or a collection type, and the value may only be a single value
 * (not multiple values).
 *
 * @param optionName name of option, only for error handling
 * @param valueStr new value of the option
 * @param type type of the object
 * @param secondaryOption the optional second annotation of the option (needs to fit to the type)
