Enum Constant Detail

INDEXED_RECORDS

public static final CommonConnectorFeature INDEXED_RECORDS

Indicates that the connector handles indexed records (i.e. records whose field identifiers are zero-based indices).

MAPPED_RECORDS

public static final CommonConnectorFeature MAPPED_RECORDS

Indicates that the connector handles mapped records (i.e. records whose field identifiers are strings).

DATA_SIZE_SAMPLING

public static final CommonConnectorFeature DATA_SIZE_SAMPLING

Indicates that the connector supports data sampling for performance optimization purposes. Data size sampling is typically done when using the connector for reading, in which case a sample of the data is read before the actual read operation begins. If the data source cannot be read more than once, then data size sampling should be disallowed. This is notably the case when reading live data streams such as standard input.

Method Detail

values

public static CommonConnectorFeature[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (CommonConnectorFeature c : CommonConnectorFeature.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static CommonConnectorFeature valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
