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.
