Enum EContentTransferEncoding

java.lang.Object

java.lang.Enum<EContentTransferEncoding>

com.helger.mail.cte.EContentTransferEncoding

All Implemented Interfaces:

com.helger.commons.id.IHasID<String>, IContentTransferEncoding, Serializable, Comparable<EContentTransferEncoding>

public enum EContentTransferEncoding
extends Enum<EContentTransferEncoding>
implements IContentTransferEncoding

Predefined Content Transfer Encoding types as per https://www.ietf.org/rfc/rfc2045.txt section 6.1.
Of course additional transfer encodings can be used.

Three transformations are currently defined: identity, the "quoted- printable" encoding, and the "base64" encoding. The domains are "binary", "8bit" and "7bit".

The Content-Transfer-Encoding values "7bit", "8bit", and "binary" all mean that the identity (i.e. NO) encoding transformation has been performed. As such, they serve simply as indicators of the domain of the body data, and provide useful information about the sort of encoding that might be needed for transmission in a given transport system.

Enum Constant Detail

_7BIT

public static final EContentTransferEncoding _7BIT

"7bit data" refers to data that is all represented as relatively short lines with 998 octets or less between CRLF line separation sequences [RFC-821]. No octets with decimal values greater than 127 are allowed and neither are NULs (octets with decimal value 0). CR (decimal value 13) and LF (decimal value 10) octets only occur as part of CRLF line separation sequences.

_8BIT

public static final EContentTransferEncoding _8BIT

"8bit data" refers to data that is all represented as relatively short lines with 998 octets or less between CRLF line separation sequences [RFC-821]), but octets with decimal values greater than 127 may be used. As with "7bit data" CR and LF octets only occur as part of CRLF line separation sequences and no NULs are allowed.

BINARY

public static final EContentTransferEncoding BINARY

"Binary data" refers to data where any sequence of octets whatsoever is allowed.

QUOTED_PRINTABLE

public static final EContentTransferEncoding QUOTED_PRINTABLE

BASE64

public static final EContentTransferEncoding BASE64

Field Detail

AS2_DEFAULT

public static final EContentTransferEncoding AS2_DEFAULT

AS2 default CTE is "binary"

Method Detail

values

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

Returns:

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

valueOf

public static EContentTransferEncoding 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

getID

 @Nonempty
public String getID()
