Method Detail

convertValue

public static <T> T convertValue(Object rawValue,
                                 Class<?> clazz)

Tries to convert the raw value into the provided type.

Type Parameters:

T - type of the result

Parameters:

rawValue - rawValue to convert into the provided type clazz

clazz - clazz specifying the target type

Returns:

the converted value if rawValue is of type clazz

Throws:

IllegalArgumentException - if the rawValue cannot be converted in the specified target type clazz

convertToEnum

public static <E extends Enum<?>> E convertToEnum(Object o,
                                                  Class<E> clazz)

canBePrefixMap

public static boolean canBePrefixMap(ConfigOption<?> configOption)

Maps can be represented in two ways.

With constant key space:

     avro-confluent.properties = schema: 1, other-prop: 2
 

Or with variable key space (i.e. prefix notation):

     avro-confluent.properties.schema = 1
     avro-confluent.properties.other-prop = 2
 

filterPrefixMapKey

public static boolean filterPrefixMapKey(String key,
                                         String candidate)

Filter condition for prefix map keys.

convertToPropertiesPrefixKey

public static Map<String,String> convertToPropertiesPrefixKey(Map<String,String> confData,
                                                              String prefixKey)

convertToPropertiesPrefixKey

public static Map<String,String> convertToPropertiesPrefixKey(Iterable<Map.Entry<String,String>> confData,
                                                              String prefixKey,
                                                              java.util.function.Predicate<String> valuePredicate)
