Method Detail

values

public static DynamoDbType[] 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 (DynamoDbType c : DynamoDbType.values())
    System.out.println(c);

Returns:

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

valueOf

public static DynamoDbType 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

toByteValue

public byte toByteValue()

Returns the byte value representation of this DynamoDbType. The byte value is used for serialization and deserialization.

• "0" represents STRING.
• "1" represents NUMBER.
• "2" represents BOOLEAN.
• "3" represents NULL.
• "4" represents BINARY.
• "5" represents STRING_SET.
• "6" represents NUMBER_SET.
• "7" represents BINARY_SET.
• "8" represents LIST.
• "9" represents MAP.

fromByteValue

public static DynamoDbType fromByteValue(byte value)

Creates a DynamoDbType from the given byte value. Each DynamoDbType has a byte value representation.
