Method Details

build

public static Object build(Class<?> clazz,
 Map<String,Object> args,
 List<ParameterProvider> paramProviders)

Build algorithm component given a set of parameters

Parameters:

clazz - Algorithm component class

args - arguments for the constructor

Returns:

instance if class built with the given params

getProvidedValue

public static Object getProvidedValue(Parameter p,
 List<ParameterProvider> paramProviders)

getProvidedValue

public static Object getProvidedValue(Class<?> pType,
 String pName,
 List<ParameterProvider> paramProviders)

findConstructor

public static <T> Constructor<T> findConstructor(Class<T> clazz,
 Map<String,Class<?>> mandatoryParams,
 List<ParameterProvider> optionalParams)

Find a constructor method in the target class that accepts the given combination of parameter (name, type) in any order. Autoboxing and widening are allowed, example from int to double, or int to Integer.

Type Parameters:

T - Constructor for class T

Parameters:

clazz - target class

mandatoryParams - argument map of all parameters that must be used

optionalParams - argument map of all parameters that might be used if necessary

Returns:

Constructor if found one that matches the given parameters, null if no constructor matches

findAutoconfigConstructor

public static <T> Constructor<T> findAutoconfigConstructor(Class<T> clazz)

Analyze an algorithm component class to find which constructor is annotated with @AutoconfigConstructor

Parameters:

clazz - Algorithm component to analyze

Returns:

constructor annotated with @AutoconfigConstructor if present, null otherwise

isAssignable

public static boolean isAssignable(Class<?> origin,
 Class<?> target)

prepareParameterValue

public static Object prepareParameterValue(Object value,
 Class<?> target)

prepareNumericParameterValue

public static Object prepareNumericParameterValue(Number value,
 Class<?> target)

checkLoss

public static void checkLoss(double value,
 double reference)
